Measurement of the Dynamical Structure Factor of a 1D Interacting Fermi Gas
T. L. Yang, P. Grišins, Y. T. Chang +4
We present measurements of the dynamical structure factor of an interacting one-dimensional (1D) Fermi gas for small excitation energies. We use the two lowest hyperfine l…
Theoretical study of stimulated and spontaneous Hawking effects from an acoustic black hole in a hydrodynamically flowing fluid of light
Pjotrs Grisins, Hai Son Nguyen, Jacqueline Bloch +2
We propose an experiment to detect and characterize the analog Hawking radiation in an analog model of gravity consisting of a flowing exciton-polariton condensate. Under a suitabl…
Highly nonlocal optical nonlinearities in atoms trapped near a waveguide
Ephraim Shahmoon, Pjotrs Grisins, Hans Peter Stimming +2
Nonlinear optical phenomena are typically local. Here we predict the possibility of highly nonlocal optical nonlinearities for light propagating in atomic media trapped near a nano…
Metropolis-Hastings thermal state sampling for numerical simulations of Bose-Einstein condensates
Pjotrs Grišins, Igor E Mazets
We demonstrate the application of the Metropolis-Hastings algorithm to sampling of classical thermal states of one-dimensional Bose-Einstein quasicondensates in the classical field…
Coherence and Josephson oscillations between two tunnel-coupled one-dimensional atomic quasicondensates at finite temperature
Pjotrs Grisins, Igor E. Mazets
We revisit the theory of tunnel-coupled atomic quasicondensates in double-well elongated traps at finite temperatures. Using the functional-integral approach, we calculate the rela…
Thermalization in a one-dimensional integrable system
Pjotrs Grisins, Igor E. Mazets
We present numerical results demonstrating the possibility of thermalization of single-particle observables in a one-dimensional integrable system (a quasicondensate of ultra-cold,…
