Postdoc opening at IPhT, CEA-Saclay: Driven Dissipative Quantum Systems

Applications are invited to fill a postdoctoral position in the condensed matter/statistical physics group at the Institute for Theoretical Physics (IPhT) of CEA Saclay. The focus will be on driven and dissipative quantum many body systems, broadly intended, including models of light-matter systems out of equilibrium (cavity/circuit QED arrays,..), dissipative quantum spin chains, as well as mesoscopic quantum circuits coupled to electromagnetic resonators.

 The theoretical activity will be carried out at IPhT in collaboration with Marco Schiro’ and Gregoire Misguich, and it will benefit from interactions with other groups in the Paris-Saclay campus actively working on related topics both on the theory and the experimental side. Candidates with research experience in either non-equilibrium many body physics, condensed matter theory, quantum information and quantum optics are especially encouraged to apply. Depending on the project and candidate’s expertise and preferences the work might range from mainly analytical to largely numerical.
Applications including (a) a letter of motivation (b) a description of research interests (c) a CV with list of publications/preprints and (d) three letters of recommendation should be uploaded online, no later than November 30 2016, through AcademicJobsOnline.

Title:Breakdown of Thermalization in Disordered Quantum Systems: Many Body Localization and its Consequences
Internship location: IPhT, CEA-Saclay
Funding: CEA

Abstract

The question of whether isolated interacting quantum many body systems can “thermalize”, namely approach thermal equilibrium under their own unitary dynamics, is a venerable one in quantum statistical mechanics. Recent theoretical and experimental investigations triggered a new wave of interest onto this fundamental problem suggesting that quenched random disorder can provide a generic and robust mechanism for thermalization-breakdown, via the phenomenon of Many Body Anderson Localization (MBL). While some intriguing properties of this non-ergodic phase of quantum matter have been explored, specifically concerning entanglement growth, broken symmetry phases or persistent memory of initial conditions, many questions remain wide open.

The goal of this internship is to investigate specifically the dynamical consequences of MBL, by studying models of disordered quantum systems out of equilibrium. Different theoretical tools will be used, depending on the strength and expertise of the candidate, ranging from numerical methods (exact diagonalization and its variants) to analytical approaches on simplified models.

Internship proposal

Title:Quantum Phase Transitions in Open Dissipative Light-Matter Systems
Internship location: IPhT, CEA-Saclay
Funding: CEA

Recent years have seen an enormous increase in the level of control over light-matter interactions at the genuine quantum level with both atomic and solid-state systems. These major experimental achievements have brought forth a novel class of systems where light and matter play equally important roles in emergent quantum many body phenomena. A crucial feature of this kind of systems is their intrinsic non equilibrium nature: indeed unavoidable photon losses, together with the possibility of feeding in additional photons through continuous external driving, make them open quantum many body systems. Under the influence of driving and dissipation they can display interesting steady states undergoing quantum phase transitions with new universal properties.

The goal of this internship project is to study the effect of photon dissipation on a prototype example of light-matter phase transition, the Dicke super-radiance. To this extent we will compute several observables and characterize the phase diagram as a function of light-matter coupling and dissipation. The stage will be theoretical, at the rich interface between non equilibrium statistical physics, quantum condensed matter and quantum optics, and will make use of analytical techniques (large spin approach, Keldysh Field Theory) and/or simple numerical calculations.

Postdoc opening at IPhT, CEA-Saclay (CLOSED)

Applications are invited to fill a postdoctoral position in condensed matter theory and quantum statistical physics at the Institute for Theoretical Physics (IPhT) of CEA Saclay.

The position is funded by the LABEX PALM through the project DynIntDisQuant, whose aim is to explore dynamical phenomena in interacting and disordered quantum systems far from thermal equilibrium.

Candidates with research experience in either non equilibrium quantum physics or disordered systems are especially encouraged to apply. Depending on the project and candidate’s expertise and preferences, the work might range from largely analytical to purely numerical.

The fellowship is for 2 years, with a flexible starting date in 2016, and includes competitive salary and benefits. The IPhT is located on the Saclay Plateau, about 40 minutes southwest of central Paris along the RER B train line, with dedicated commuter buses to and from various locations in Paris. Interactions with other researchers working on related topics both at the IPhT and in the Paris Area will be encouraged.

Applications including (a) a letter of motivation (b) a description of research interests (c) a CV with list of publications/preprints and (d) three letters of recommendation should be sent to Marco Schiro’ by email at the address marco.schiro@cea.fr or uploaded online through AcademicJobsOnline.

Review of applications will begin on December 15th 2015 and will continue until the position is filled. For further information and inquiries please contact: marco.schiro@cea.fr
