Yashar Akrami (2018-2021)
PhD : Oskar Klein Center (Stockholm) ; Postdocs : Leiden University, Heidelberg University, University of Oslo.
Yashar is a theoretical physicist specialised in cosmology and particle physics, with a broad range of interests. He has also a strong interest in cosmological data analysis and his focus is on the interplay between cosmological observations and fundamental physics.
Yashar is interested in questions related to the physics of the early universe and cosmic initial conditions, late-time cosmic acceleration and dark energy, theories of gravity on the largest scales, signatures of new physics beyond standard models of cosmology and particle physics, and implications of high energy theories (quantum gravity, string theory, supergravity) for cosmology.
On the observational side, he is interested in the cosmic microwave background, large-scale structure of the universe, and statistical inference and high-performance computing techniques in cosmology and particle physics. He is an active member of the Planck Collaboration, Euclid Consortium, and the Square Kilometre Array (SKA).

Badih Assaf (2014-2018) / Currently Assistant Professor, University of Notre Dame (Indiana, US)
BS : American University of Beirut ; Graduate student at Northeastern University in Heiman group and visiting scientist at MIT with the Moodera group
Badih’s research interests are primarily focused on studying and understanding the electronic properties of 2D materials and topological insulators. The most common 2D material is graphene which is essentially a single atomic sheet of carbon. Topological insulators, on the other hand, are 3D materials that are semiconducting in the bulk but highly conducting on the surface. Such materials are extremely attractive as potential silicon alternatives in data processing devices as well as for applications in memory devices and optoelectronics.
His PhD involved quantum coherent transport in topological insulator thin films grown by molecular beam epitaxy, along with studying the properties of novel spin-gapless Heusler alloys.
As a JRC, he worked on probing the fundamental electronic properties of 2D materials as well as different topological material systems (Bi2Se3, Bi2Te3…) using gigahertz transport probes and terahertz spectroscopy.

BA & MMath : Mathematical Tripos at the University of Cambridge, Gonville and Caius College ; PhD : DAMTP, Prof. P. Shellard, University of Cambridge ; Postdoc : InDark fellow at INFN (Padua, Italy)
As a theoretical physicist he studies the effects of topological defects on the Cosmic Microwave Background and the inflationary bispectrum of the large-scale structure of the Universe. He also focused on the analytical modelling of the matter bispectrum of large-scale structure and on obtaining forecasts for primordial non-Gaussianity.
At ENS, he developed analytical and numerical techniques to model the galaxy bispectrum in order to place stringent constraints on cosmological parameters. These involve both work to model the matter bispectrum towards the nonlinear regime, as well as accurate large-scale studies for the galaxy bispectrum. Part of the work is being pursued in the framework of the Euclid Consortium. He also studies models of dark energy and modified gravity, and in particular he focuses on employing three-point correlation functions to constrain parameters of these models.

First working on bosonic quantum gases, in artificial gauge fields and driven optical lattices, his research includes the field of strongly interacting, ultracold Fermi gases focused on Fermi Liquid behavior, hydrodynamics, phonon decay and short-range correlations.
As a JRC at LKB, Julian conceived, planned and supervised pioneering experiments on individually resolved ultracold atomic Fermi gases in the 1D regime and 1D-3D crossover. His studies covered a broad variety of topics ranging from thermodynamics to out-of-equilibrium phenomena and transport with strong interactions.
