Generalized Higgs mechanism in long-range-interacting quantum systems
Physical Review Research, 2023 The physics of long-range-interacting quantum systems is currently living through a renaissance driven by the fast progress in quantum simulators. In these systems many paradigms of statistical physics do not apply and also the universal long-wavelength ...

Bogoliubov-de Gennes study of trapped spin-imbalanced unitary Fermi gases
, 2011 It is quite common that several different phases exist simultaneously in a system of trapped quantum gases of ultra-cold atoms. One such example is the strongly-interacting Fermi gas with two imbalanced spin species, which has received a great amount of ...

From a continuous to a discrete time crystal in a dissipative atom-cavity system
New Journal of Physics, 2020 We propose the dynamical stabilization of a nonequilibrium order in a driven dissipative system comprised an atomic Bose–Einstein condensate inside a high finesse optical cavity, pumped with an optical standing wave operating in the regime of anomalous ...

Two-dimensional quantum droplets in dipolar Bose gases
New Journal of Physics, 2019 We calculate analytically the quantum and thermal fluctuations corrections of a dilute quasi-two-dimensional Bose-condensed dipolar gas. We show that these fluctuations may change their character from repulsion to attraction in the density-temperature ...

Number fluctuations in cold quantum gases
, 2007 In ultracold gases many experiments use atom imaging as a basic observable. The resulting image is averaged over a number of realizations and mostly only this average is used. Only recently the noise has been measured to extract physical information.

Fragility of the fractional quantum spin Hall effect in quantum gases
New Journal of Physics, 2014 We consider the effect of contact interaction in a prototypical quantum spin Hall system of pseudo-spin-1/2 particles. A strong effective magnetic field with opposite directions for the two spin states restricts two-dimensional particle motion to the ...

Frictionless quantum quenches in ultracold gases: a quantum dynamical microscope
, 2011 In this article, a method is proposed to spatially scale up a trapped ultracold gas while conserving the quantum correlations of the initial many-body state.

Creating and probing the Sachdev-Ye-Kitaev model with ultracold gases: Towards experimental studies of quantum gravity [PDF]
, 2016 We suggest that the holographic principle, combined with recent technological advances in atomic, molecular, and optical physics, can lead to experimental studies of quantum gravity.

New Journal of Physics, 2015 We derive a systematic high-frequency expansion for the effective Hamiltonian and the micromotion operator of periodically driven quantum systems. Our approach is based on the block diagonalization of the quasienergy operator in the extended Floquet ...
