Research project:

The fields of quantum science and technology have experienced remarkable recent progress, largely fueled by the development of quantum platforms that offer high-fidelity control over individual quantum degrees of freedom. Laser-cooled neutral atoms, in particular, have become a successful and versatile platform for applications like quantum simulation, quantum metrology, and digital quantum computing. Prime examples of this advancement include quantum-gas microscopes utilizing atoms in optical lattices, and Rydberg atomic arrays based on optical-tweezer traps.

Our experimental project aims to construct a novel ultracold-atom experiment designed to exploit the high programmability of individual optical tweezers for preparing low-entropy quantum many-body systems. This new experimental apparatus, to be built in the Physics Faculty of the Universitat de Barcelona (UB), will combine the best features of optical tweezers and optical lattices to create a versatile machine for quantum simulation and quantum optics studies. Specifically, we will follow a bottom-up approach: atoms will first be trapped, detected, and cooled close to their motional ground state before being precisely combined into interacting many-atom systems.

A primary goal for this new machine will be to delve into the study of interacting many-body quantum walks. This research direction could be used to efficiently sample certain quantum states, a problem with high computational complexity currently discussed in the context of probing quantum advantage. In a different direction, our system might provide an alternative route towards the preparation of ground states in systems of ultracold atoms, over conventional evaporative cooling techniques. Finally, our platform will also offer a way of probing cooperative light-matter phenomena in well-defined atomic ensembles.

Tasks to be performed by the PhD student:

The successful candidate will play a key role in the design, construction and demonstration of a novel quantum platform based on laser-cooled atoms. As a whole, this PhD project will take place at the intersection of atomic physics, quantum science and hands-on experimental engineering. Many fundamental techniques of cold-atom physics techniques will be mastered during the project, such as magneto-optical trapping, Raman sideband cooling and single-atom trapping and detection. On the technical side, the project will involve tasks requiring ultra-high vacuum systems, the assembly of photonic laser systems as well as the use of control electronics.

The PhD student will work in a small team of experimentalists, with a total of 3-4 members, led by Dr. Antonio Rubio-Abadal. To fulfill the goals of the project, the team will also stay in close contact with theory collaborators within the department (ManboQu), as well with the other quantum labs at UB (QComms). Additionally, the team will also benefit from working within the vibrant network of quantum research in the area of Barcelona.

The Institute of Cosmos Sciences of the University of Barcelona (ICCUB) invites applications for a 3-year Postdoctoral position in Beyond the standard models of cosmology and particle physics, as part of its current call for two postdoctoral positions and one ICCUB Postdoctoral Fellowship, offered under the framework of its Unit of Excellence Maria de Maeztu. 

These positions are part of a dynamic and interdisciplinary research environment at one of Europe’s leading centers in cosmology, astrophysics, and particle physics. The Institute of Cosmos Sciences (ICCUB) at the University of Barcelona, established in 2006, focuses on cosmology, astrophysics, particle physics, quantum physics, and nuclear physics. With over 70 scientists, 20 engineers, and 90 postdoctoral researchers and PhD students (35% international), ICCUB collaborates internationally on projects like Gaia, LHCb, Virgo, MAGIC, CTA, and DESI. It also has an Advanced Technology Unit supporting experimental research requiring cutting-edge technology. 

Description of the postdoctoral position:

Efforts to understand the ultimate laws of nature and the structure and composition of the Universe have so far been carried out almost independently within the fields of particle physics, astrophysics, and cosmology. This siloing is now hampering progress, as the disciplines that study the very large and the very small have become inextricably intertwined. Each has converged to its own extremely successful Standard Model (SM): the SM of particle physics (PP) and the standard cosmological model or Lambda Cold Dark Matter (LCDM) model, with many aspects in common. Yet both models show signs of being incomplete, pointing to the need for new physics with profound implications for our understanding of matter, forces, and the Universe's components themselves.

Finding out what that new physics may or may not be can only be achieved with a coordinated approach from theoretical modelling to data analysis, and a holistic context covering expertise in all the disciplines involved.  The successful candidate should have demonstrated expertise and interest  in one or more of these aspects:  

- Precision measurements in Experimental Particle Physics  

- Robust analysis and interpretation of  cosmological data especially galaxy surveys

- Neutrino properties at the intersection of particle physics and cosmology 

- Dark matter distribution, clustering and detection from cosmic scales down to Earth. 

The successful candidate is expected to work across different research groups at the ICCUB:

• Cosmology and Large Scale Structure
• Particle Physics Phenomenology
• Galaxy Structure and Evolution
• Experimental High Energy Physics

Requirements:

Applicants must hold a PhD in Physics, Astrophysics, or a closely related field by the start date of the contract, approximately in October 2026. We are looking for motivated researchers with a strong track record and a collaborative spirit.

Employment Terms:

• Duration: up to 3 years
• Start Date: Preferably by Fall 2026 (flexibility possible for parental or special circumstances)
• Salary: 
  • Maria de Maeztu Postdoctoral Positions: Approx. 36.360€/year (gross), including full social security and public healthcare coverage for the researcher, spouse or registered partner and children
  • ICCUB Postdoctoral Fellowship: Approx. 42.900€/year (gross), including full social security and public healthcare coverage for the researcher, spouse or registered partner and children
• Research Support:

The Hubble constant, H₀, that measures the current expansion rate of the Universe is one of the key parameters of the cosmological model. It can be measured from the Cosmic Microwave Background or directly in the local Universe. While the two measurements should give the same value, as they measure the same universe, they do not agree in practice. This can be a sign that the cosmological model does not describe well-enough our universe, or that the measurements of H₀ somehow suffer from systematics. One fully independent way of measuring H₀ locally is to use the so-called time delays in strongly lensed quasars, in combination with detailed models of the potential well for the galaxy(ies) responsible for the lensing effect. The PhD is fully devoted to the measurement of H₀ with strong lenses and will involve lens modeling, dynamical modeling of lenses as well as processing of HST and JWST observations of such objects. This work, and therefore the student, is/will be part of the TDCOSMO collaboration.

The student will join the new research group of Prof. Frédéric Courbin, at ICCUB but will of course benefit from and contribute to the other groups in observational cosmology at ICCUB.

Description of the group:

F. Courbin works in close collaboration with the ICCUB Physical Cosmology group (Profs. Verde, Jimenez, Gil-Marin), studying connections between theory and observations in large sky surveys. F. Courbin is more oriented towards observations and modeling but also has a strong signal processing component in his research, as a full member of the ESA Euclid mission and as one of the leads of strong lensing in Euclid. He also collaborate with the cosmostat group in CEA-Saclay.

The Stellar Physics group at the ICCUB welcomes expressions of interest from outstanding postdoctoral researchers to jointly apply for the 2025 Marie Skłodowska-Curie Postdoctoral Fellowship (MSCA-PF-2025) through the European Commission. The group offers expert mentoring and comprehensive guidance throughout the application process to help candidates develop competitive proposals.

The research developed at the Stellar Physics group covers different stages of star formation, stellar evolution all the way from dust to life, and the study of stellar environments and their planetary systems. We aim to develop a multi-scale, multi-disciplinary approach to answer these three main questions:

1 - How do stars form?

2 - How do stars evolve in isolation; in multiple systems and as a population?

3 - How does atmospheric activity (e.g., stellar winds, flares, coronal mass ejections), including the Sun, impact their environment and how does this affect the habitability of exoplanets?

To this end, the research activity of our group focuses on the following topics:

1. Star formation with a multiwavelength approach, covering from radio to high energy spectral range.
2. Evolution of stellar binary stars with time-domain astrophysical datasets (transients, variable and eclipsing systems, etc.), spectroscopic characterization, and stellar evolution models.
3. Analysis and modeling of solar particle events as well as the development of solar particle radiation interplanetary environment prediction models.
4. Understanding the impact of stellar activity (flares) over planetary atmospheres and habitability.
5. Stellar astrophysical parameter estimation and stellar characterization from astrometry, photometry, and spectroscopy.
6. Understanding different stellar populations within the Milky Way with large astrophysical datasets (Gaia, future GaiaNIR,  the spectroscopic WEAVE survey…).
7. New instrumentation for astrophysics for Montsec Observatory.

The members of the group have leading and collaboration roles in major collaborations in the field of stellar physics, such as Gaia Data Analysis and Processing Consortium, Euclid, BlackGEM time-domain survey, Transient and Variable Science collaboration within the Vera Rubin Observatory (LSST), SKA and “The VLA Orion A Large Survey” collaboration, Solar Orbiter and PLATO missions, and the UV-optical CubeSat mission PhotSat, entirely led by the Institute of Space Sciences of Catalonia (IEEC). In addition, the group has ongoing collaborations with European and international research institutions (Caltech, Radboud University, KU Leuven, Universidad Nacional de Mexico, among others), which can enhance the internationalization of our member’s research.

The group can offer support for computing time in the Institute of Cosmos Sciences cluster. The fellow will have the opportunity to develop a career development plan and be part of a mentorship program.

REQUIREMENTS:

We are excited to support candidates with expertise related to the main research areas carried in our group, both from observational and theoretical perspectives. In particular, we are interested in exploring projects that can exploit the synergies between the major research lines in stellar physics, and also with other research groups at the ICCUB, such as the high energies group, the gravitational waves group, the galaxy structure and evolution, and the technological unit.
