Modulation instability in the nonlinear Schrödinger equation with a synthetic magnetic field: gauge matters
Karlo Lelas, Ozana Čelan, David Prelogović +2
We theoretically investigate the phenomenon of modulation instability for systems obeying nonlinear Schrödinger equation, which are under the influence of an external homogeneous s…
Laser assisted tunneling in a Tonks-Girardeau gas
K. Lelas, N. Drpić, T. Dubček +3
We investigate the applicability of laser assisted tunneling in a strongly interacting one-dimensional Bose gas (the Tonks-Girardeau gas) in optical lattices. We find that the stro…
The pinning quantum phase transition in a Tonks Girardeau gas: diagnostics by ground state fidelity and the Loschmidt echo
K. Lelas, T. Ševa, H. Buljan +1
We study the pinning quantum phase transition in a Tonks-Girardeau gas, both in equilibrium and out-of-equilibrium, using the ground state fidelity and the Loschmidt echo as diagno…
Loschmidt echo in one-dimensional interacting Bose gases
K. Lelas, T. Ševa, H. Buljan
We explore Loschmidt echo in two regimes of one-dimensional (1D) interacting Bose gases: the strongly interacting Tonks-Girardeau (TG) regime, and the weakly-interacting mean-field…
Ground state properties of a one-dimensional strongly-interacting Bose-Fermi mixture in a double-well potential
K. Lelas, D. Jukić, H. Buljan
We calculate the reduced single-particle density matrix (RSPDM), momentum distributions, natural orbitals and their occupancies, for a strongly interacting one-dimensional Bose-Fer…
