Many-body effects on second-order phase transitions in spinor Bose-Einstein condensates and breathing dynamics
K. M. Mittal, S. I. Mistakidis, P. G. Kevrekidis +1
We unravel the correlation effects of the second-order quantum phase transitions emerging on the ground state of a harmonically trapped spin-1 Bose gas, upon varying the involved Z…

Semiclassical evaluation of expectation values
Kush Mohan Mittal, Olivier Giraud, Denis Ullmo
Semiclassical Mechanics allows for a description of quantum systems which preserves their phase information, while using only the system's classical dynamics as an input. Over the…

Quantum resonances of kicked rotor in the position representation
Kush Mohan Mittal, M. S. Santhanam
The study of quantum resonances in the chaotic atom-optics kicked rotor system is of interest from two different perspectives. In quantum chaos, it marks out the regime of resonant…
