Crossover polarons in a strongly interacting Fermi superfluid
Hui Hu, Jia Wang, Jing Zhou +1
We investigate the zero-temperature quasiparticle properties of a mobile impurity immersed in a strongly interacting Fermi superfluid at the crossover from a Bose-Einstein condensa…
Exponential Fermi Acceleration in a Switching Billiard
Davit Karagulyan, Jing Zhou
In this paper we show an infinite measure set of exponentially escaping orbits for a resonant Fermi accelerator, which is realised as a square billiard with a periodically oscillat…
Spectral asymptotics and Lamé spectrum for coupled particles in periodic potentials
Ki Yeun Kim, Mark Levi, Jing Zhou
We make two observations on the motion of coupled particles in a periodic potential. Coupled pendula, or the space-discretized sine-Gordon equation is an example of this problem. L…
A Piecewise Smooth Fermi-Ulam Pingpong with Potential
Jing Zhou
In this paper we study a Fermi-Ulam model where a pingpong bounces elastically against a periodically oscillating platform in a gravity field. We assume that the platform motion $f…
A Rectangular Billiard with Moving Slits
Jing Zhou
We describe an exponential Fermi accelerator in a two-dimensional billiard with a moving slit. We have found a mechanism of trapping regions which provides the exponential accelera…
Dynamical instability towards finite-momentum pairing in quenched BCS superconducting phases
Beibing Huang, Xiaosen Yang, Ning Xu +2
In this work we numerically investigate the fate of the Bardeen-Cooper-Schrieffer (BCS) pairing in the presence of quenched phase under Peierls substitution using time-dependent re…
