Quench-induced Floquet topological p-wave superfluids.
Ultracold atomic gases in two dimensions tuned close to a p-wave Feshbach resonance were expected to exhibit topological superfluidity, but these were found to be experimentally unstable. We show that one can induce a topological Floquet superfluid if weakly interacting atoms are brought suddenly close ("quenched") to such a resonance, in the time before the instability kicks in. The resulting ...
متن کاملQuench and Quench Correction
The TopCount Microplate Scintillation and Luminescence Counter is capable of analyzing radiolabeled microplate samples in a wide variety of formats using liquid and solid scintillation counting techniques. Quench is a common interference in scintillation counting which reduces the sample’s apparent activity. In most applications, the level of quench is constant; hence, it need not be considered...
متن کاملNon-Gaussian normal diffusion induced by delocalization.
Non-Gaussian normal diffusion, i.e., the probability density function (PDF) is non-Gaussian but the mean squared displacement (MSD) depends on time linearly, has been observed in particle motions. Here we show by numerical simulations that this phenomenon may manifest itself in energy diffusion along a lattice at a nonzero, finite temperature. The studied model is a one-dimensional disordered l...
متن کاملBallistic quench-induced correlation waves in ultracold gases
We investigate the wave-packet dynamics of a pair of particles that undergoes a rapid change of scattering length. The short-range interactions are modeled in the zero-range limit, where the quench is accomplished by switching the boundary condition of the wave function at vanishing particle separation. This generates a correlation wave that propagates rapidly to nonzero particle separations. W...
متن کاملQuench-induced breathing mode of one-dimensional Bose gases.
We measure the position- and momentum-space breathing dynamics of trapped one-dimensional Bose gases at finite temperature. The profile in real space reveals sinusoidal width oscillations whose frequency varies continuously through the quasicondensate to ideal Bose gas crossover. A comparison with theoretical models taking temperature into account is provided. In momentum space, we report the f...
