Title: Dynamical critical phenomena in driven-dissipative systems
Abstract:
We explore the nature of the Bose condensation transition in driven open quantum systems,
such as exciton-polariton condensates. Using a functional renormalization group approach
formulated in the Keldysh framework, we characterize the dynamical critical behavior that
governs decoherence and an effective thermalization of the low frequency dynamics.
We identify a critical exponent special to the driven system, showing that it defines a new
dynamical universality class. Hence critical points in driven systems lie beyond the standard
dynamical classification of equilibrium phase transitions. We show how the new critical
exponent can be probed in experiments with driven cold atomic systems and exciton-polariton
condensates.

>> One, two, three, many: Exploring quantum systems one atom at a time
>>
>> Experiments with ultracold gases have been extremely successful in studying
>> many body systems, such as Bose Einstein condensates or fermionic
>> superfluids. These are deep in the regime of statistical physics, where
>> adding or removing an individual particle does not matter.
>> For a few-body system this can be dramatically different. This is apparent
>> for example in nuclear physics, where adding a single neutron to a magic
>> nucleus dramatically changes its properties. In our work we
>> deterministically prepare generic model systems containing up to ten
>> ultracold fermionic atoms with tunable short range interaction.
>> In our bottom-up approach, we have started the exploration of such few-body
>> systems with a two-particle system that can be described with an analytic
>> theory. Adding more particles one by one we enter a regime in which an exact
>> theoretical description of the system is exceedingly difficult, until the
>> particle number becomes large enough such that many-body theories provide an
>> adequate approximation.

>> best, Matthias.
