Tunable-Size Unruh-DeWitt Detector in a Multimode Cavity
Simon Brunner, Farokh Mivehvar, Helmut Ritsch +1
Quantum simulators based on Bose-Einstein condensates (BECs) provide a powerful platform to study relativistic quantum-field phenomena in the lab and in particular emulate relativi…
Driven-Dissipative Landau Polaritons: Two Highly Nonlinearly-Coupled Quantum Harmonic Oscillators
Farokh Mivehvar
Landau levels (LLs) are the massively-degenerate discrete energy spectrum of a charged particle in a transverse magnetic field and lie at the heart of many intriguing phenomena suc…
Rotational Superradiance in a Time-Reversal Symmetry-Broken Quantum Gas inside an Optical Cavity
Natalia Masalaeva, Farokh Mivehvar
Appearance of quantized vortices in a superfluid and a Bose-Einstein condensate (BEC) stems from their nontrivial response to broken time-reversal symmetry (TRS). Here we show that…
Nonequilibrium Nonlinear Effects and Dynamical Boson Condensation in a Driven-Dissipative Wannier-Stark Lattice
Arkadiusz Kosior, Karol Gietka, Farokh Mivehvar +1
Driven-dissipative light-matter systems can exhibit collective nonequilibrium phenomena due to loss and gain processes on the one hand and effective photon-photon interactions on t…
