Quantum Cherenkov transition of finite momentum Bose polarons
Kushal Seetharam, Yulia Shchadilova, Fabian Grusdt +2
We investigate the behavior of a finite-momentum impurity immersed in a weakly interacting three-dimensional Bose-Einstein condensate (BEC) of ultra-cold atoms, giving a detailed a…
Dynamical quantum Cherenkov transition of fast impurities in quantum liquids
Kushal Seetharam, Yulia Shchadilova, Fabian Grusdt +2
The challenge of understanding the dynamics of a mobile impurity in an interacting quantum many-body medium comes from the necessity of including entanglement between the impurity…
Spectrum, Landau-Zener theory and driven-dissipative dynamics of a staircase of photons
J. Marino, Y. E. Shchadilova, M. Schleier-Smith +1
We study the production of photons in a model of three bosonic atomic modes non-linearly coupled to a cavity mode. In absence of external driving and dissipation, the energy levels…
Fermionic formalism for driven-dissipative multi-level systems
Yulia Shchadilova, Mor M. Roses, Emanuele G. Dalla Torre +2
We present a fermionic description of non-equilibrium multi-level systems. Our approach uses the Keldysh path integral formalism and allows us to take into account periodic drives,…
Strong coupling Bose polarons out of equilibrium: Dynamical RG approach
Fabian Grusdt, Kushal Seetharam, Yulia Shchadilova +1
When a mobile impurity interacts with a surrounding bath of bosons, it forms a polaron. Numerous methods have been developed to calculate how the energy and the effective mass of t…
Intertwined and vestigial order with ultracold atoms in multiple cavity modes
Sarang Gopalakrishnan, Yulia E. Shchadilova, Eugene Demler
Atoms in transversely pumped optical cavities "self-organize" by forming a density wave and emitting superradiantly into the cavity mode(s). For a single-mode cavity, the propertie…
