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…
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-…
BBGKY chain and kinetic equations for the level dynamics in an externally perturbed quantum system
Mumnuna A. Qureshi, Johnny Zhong, Joseph J. Betouras +1
Theoretical description and simulation of large quantum coherent systems out of equilibrium remains a daunting task. Here we are developing a new approach to it based on the Pechuk…
