Minimal Fokker-Planck theory for the thermalization of mesoscopic subsystems
Igor Tikhonenkov, Amichay Vardi, James R. Anglin +1
We explore a minimal paradigm for thermalization, consisting of two weakly-coupled, low dimensional, non-integrable subsystems. As demonstrated for Bose-Hubbard trimers, chaotic er…
Robust sub-shot-noise measurement via Rabi-Josephson oscillations in bimodal Bose-Einstein condensates
I. Tikhonenkov, M. G. Moore, A. Vardi
Mach-Zehnder atom interferometry requires hold-time phase-squeezing to attain readout accuracy below the standard quantum limit. This increases its sensitivity to phase-diffusion,…
Optimal Gaussian squeezed states for atom-interferometry in the presence of phase diffusion
Igor Tikhonenkov, Michael G. Moore, Amichay Vardi
We optimize the signal-to-noise ratio of a Mach-Zehnder atom interferometer with Gaussian squeezed input states, in the presence interactions. For weak interactions, our results co…
Rapid phase-diffusion between atomic and molecular Bose-Einstein condensates
I. Tikhonenkov, A. Vardi
We study the collisional loss of atom-molecule coherence after coherently dissociating a small fraction of a molecular Bose-Einstein condensate into atoms. The obtained -atoms s…
Vortex solitons in dipolar Bose-Einstein Condensates
I. Tikhonenkov, B. A. Malomed, A. Vardi
We predict solitary vortices in quasi-planar condensates of dipolar atoms, polarized parallel to the confinement direction, with the effective sign of the dipole-dipole interaction…
Confinement controlled dissociation of a molecular Bose-Einstein condensate
I. Tikhonenkov, A. Vardi
We study the collective two-channel dissociation dynamics of a molecular Bose-Einstein condensate into bosonic fragments under tight harmonic confinement. Bose-stimulated dissociat…
