Pechukas-Yukawa formalism for Landau-Zener transitions in the presence of external noise
Mumnuna A. Qureshi, Johnny Zhong, Peter Mason +2
Quantum systems are prone to decoherence due to both intrinsic interactions as well as random fluctuations from the environment. Using the Pechukas-Yukawa formalism, we investigate…
Time-dependent Real-space Renormalization-Group Approach: application to an adiabatic random quantum Ising model
Peter Mason, Alexandre Zagoskin, Joseph Betouras
We develop a time-dependent real-space renormalization-group approach which can be applied to Hamiltonians with time-dependent random terms. To illustrate the renormalization-group…
Pechukas-Yukawa approach to the evolution of the quantum state of a parametrically perturbed system
Mumnuna A Qureshi, Johnny Zhong, Zihad Qureshi +3
We consider the evolution of a quantum state of a Hamiltonian which is parametrically perturbed via a term proportional to the adiabatic parameter λ(t). Starting with the Pechukas-…
Beyond Thomas--Fermi analysis of the density profiles of a miscible two-component Bose--Einstein condensate
J. Polo, P. Mason, S. Sridhar +3
We investigate a harmonically trapped two-component Bose--Einstein condensate within the miscible regime, close to its boundaries, for different ratios of effective intra- and inte…
Number-conserving approaches to -component Bose-Einstein condensates
Peter Mason, Simon Gardiner
We develop the number-conserving approach that has previously been used in a single component Bose-Einstein condensed dilute atomic gas, to describe consistent coupled condensate a…
Phase diagrams and Thomas-Fermi estimates for spin-orbit coupled Bose-Einstein Condensates under rotation
Amandine Aftalion, Peter Mason
We provide complete phase diagrams describing the ground state of a trapped spinor BEC under the combined effects of rotation and a Rashba spin-orbit coupling. The interplay betwee…
