Sponsored by ”la Caixa” Foundation, it is aimed at supporting the best scientific talent and fostering innovative and high-quality research in Spain and Portugal by recruiting outstanding international students and offering them an attractive and competitive environment for conducting research of excellence.
The Institute of Cosmos Sciences of the University of Barcelona is a research centre accredited with the Spanish Seal of Excellence María de Maeztu in 2020, the perfect place to carry out your PhD project through an INPhINIT Incoming fellowship.
Research Project:
We are currently entering the so-called second quantum revolution, where the high control of nature at the smallest scales is allowing us to build a fantastic set of new technology based on quantum mechanics. Among the many open fronts, a fascinating one is the possibility of producing human taylor made new materials with exoctic quantum properties, e.g. new superfluids.
There is important experimental progress in the field of ultradilute quantum gases in the last few years, in particular, in the realization of ultradilute quantum liquids and dipolar gases. Ultracold atomic systems are a perfect testbed for quantum theories for three main reasons:
(i) They are extremely pure and defect free
(ii) They are highly controllable in terms of the interactions between atoms
(iii) The trapping potentials can be custom made, i.e. lattices, 1D systems, etc.
Recently, quantum ultradilute liquids have been experimentally created in the experimental group of Prof. Tarruell at ICFO (Spain) [1], featuring densities that are eight orders of magnitude more dilute as compared to the usual ones. Such many-body systems are self-bound, akin to liquid drops or nuclei. It is of great interest to study their properties and to predict the possible existence of such ultradilute liquids in other systems, i.e. in lattice-trapped atoms [2,3]. In another important recent experiment in the group of Prof. Lev (Stanford), a topological pumping mechanism has been experimentally produced in dysprosium gases trapped in 1D systems [4]. Interestingly, in this case, the atoms feature long-range dipolar interactions, opening the possibility of building quantum simulators of materials featuring exotic quantum phases.

Job position description
The research project aims at providing an accurate ab initio description by means of state-of-the-art Montecarlo and Tensor networks tools, combined with analytical tools and exact diagonalization calculations. The ICCUB group has ample experience in using tensor networks, exact diagonalization and analytical tools. The project will be cosupervised by Prof. Astrakharchik, a long-term collaborator of the group, currently on a one-year stay in the group, who is a world expert in Monte Carlo methods applied to many-body quantum systems. The research group is currently composed of five senior members, three visiting professors, one postdoc, and two PhD students.
The main objectives of this work are:
● Theoretically study the physical properties of state-of-the-art exotic quantum fluids produced in ultracold atomic laboratories worldwide.
● Learn and apply the Tensor networks and Montecarlo techniques to study many-body quantum systems, in particular exotic quantum liquids and low-dimensional quantum many-body systems.
The fellow will join the Quantum Technologies area of the ICCUB and will participate actively in our Quantum Technologies meetings and seminars. The student will join our network of international collaborators.
During the PhD period, the student will participate in Schools and Workshops to strengthen his/her background, and will be encouraged to present the results of the research at international conferences. The fellow is expected to learn: i) Performing theoretical and computational high-quality research; ii) Participating in the preparation of manuscripts for publication and presentations at scientific conferences.

Working at the Institute of Cosmos Sciences
The Institute of Cosmos Sciences is a research institute of the University of Barcelona. It is an interdisciplinary centre dedicated to fundamental research in the fields of cosmology, astrophysics, and particle physics. In addition, the institute has a strong technology program through its participation in international collaborations in observational astronomy and experimental particle physics.
Moreover, the ICCUB participates in many key international scientific consortia and projects, such as the Large Hadron Collider, the Gaia astrometric space mission, the MAGIC / CTA high-energy astrophysics telescopes, and the Virgo gravitational wave detector, among others. Additional information about the Institute and the University of Barcelona can be found here.
You will be encouraged to contribute and interact with other researchers in the vibrant and international research environment as well as to participate in our outreach initiatives, more information at serviAstro and serviParticules.
As part of the University of Barcelona, the ICCUB is a recipient of the European Commission’s HR Excellence in Research (HRS4R) Award, which recognises, among other achievements, respect for equal opportunities and the capacity to attract talent in a positive working environment that promotes the pursuit of successful research careers. The ICCUB respects the principles of open, transparent, merit-based selection. We strongly encourage women and underrepresented minorities in physical sciences to apply. For additional information please see the Diversity, equity and inclusion Commission.
The ICCUB is located in Barcelona, considered the 8th World's Best Cities 2021: one with near-perfect weather year-round, miles and miles of beaches, iconic parks, striking architecture and colourful neighbourhoods that march to their own beat—artistic, sophisticated, bohemian.

Requirements
In order to be accepted, candidates must meet the following eligibility requirements:
- Experience: At the call deadline, applicants must be in the first four years (full-time equivalent research experience) of their research careers and not yet have been awarded a doctoral degree or be in a position to apply for one.
- Studies pursued: Applicants must hold a higher education degree that makes them eligible to enroll in a doctoral programme before starting at their host institutions.
The host university will verify, upon starting the admission process to the doctoral programme, that the studies taken up by the selected candidates make them eligible to enroll in an official doctoral programme in accordance with the regulations in force in Spain or Portugal. Should they be found not eligible after verification, the fellowship will be withdrawn.
Under no circumstances may candidates have previously enrolled in the same doctoral studies for which they are applying for the fellowship.
