Beliaev damping in Bose gas
Jan Dereziński, Ben Li, Marcin Napiórkowski
According to the Bogoliubov theory the low energy behaviour of the Bose gas at zero temperature can be described by non-interacting bosonic quasiparticles called phonons. In this w…
Exact values of quantum violations in low-dimensional Bell correlation inequalities
Ben Li
The famous Clauser-Horne-Shimony-Holt (CHSH) inequality certifies a quantum violation, by a factor , of correlations predicted by the classical view of the world in the s…
Exotic Multi-fold Vortex Lattices of Spin-Orbit Coupled Bose-Einstein Condensates in Optical Lattices
Ben Li, Shu Chen
We investigate the ground state of two-dimensional Bose-Einstein condensates with Rashba spin-orbit coupling in square optical lattices and demonstrate the existence of rich phases…
Bound on Bell Inequalities by Fraction of Determinism and Reverse Triangle Inequality
P. Joshi, K. Horodecki, M. Horodecki +5
It is an established fact that entanglement is a resource. Sharing an entangled state leads to non-local correlations and to violations of Bell inequalities. Such non-local correla…
The creation of two-dimensional composite solitons in spin-orbit-coupled self-attractive Bose-Einstein condensates in free space
Hidetsugu Sakaguchi, Ben Li, Boris A. Malomed
It is commonly known that two-dimensional mean-field models of optical and matter waves with the cubic self-attraction cannot produce stable solitons in free space because of the o…
Vortex lattice solutions to the Gross-Pitaevskii equation with spin-orbit coupling in optical lattices
Hidetsugu Sakaguchi, Ben Li
Effective spin-orbit coupling can be created in cold atom systems using atom-light interaction. We study the BECs in an optical lattice using the Gross-Pitaevskii equation with spi…
