Landau-Zener Tunneling of Solitons
Vazha Loladze, Ramaz Khomeriki
A simple mechanical analog describing Landau-Zener tunneling effect is proposed using two weakly coupled chains of nonlinear oscillators with gradually decreasing (first chain) and…
Driven Macroscopic Quantum Tunneling of Ultracold Atoms in Engineered Optical Lattices
Ramaz Khomeriki, Stefano Ruffo, Sandro Wimberger
Coherent macroscopic tunneling of a Bose-Einstein condensate between two parts of an optical lattice separated by an energy barrier is theoretically investigated. We show that by a…
Ratchet-Like Solitonic Transport in Quantum Hall Bilayers
Ramaz Khomeriki, Lasha Tkeshelashvili, Tinatin Buishvili +1
The pseudo-spin model for double layer quantum Hall system with total landau level filling factor is discussed. Unlike the "traditional" one where interlayer voltage enters a…
