Range of applicability of the Hu-Paz-Zhang master equation
G. Homa, A. Csordás, M. A. Csirik +1
We investigate a case of the Hu-Paz-Zhang master equation of the Caldeira-Leggett model without Lindblad form obtained in the weak-coupling limit up to the second-order perturbatio…
Short time behavior of continuous time quantum walks on graphs
Balázs Endre Szigeti, Gábor Homa, Zoltán Zimborás +1
Dynamical evolution of systems with sparse Hamiltonians can always be recognized as continuous time quantum walks (CTQWs) on graphs. In this paper, we analyze the short time asympt…
Positivity violations of the density operator in the Caldeira-Leggett master equation
G. Homa, J. Z. Bernád, L. Lisztes
The Caldeira-Leggett master equation as an example of Markovian master equation without Lindblad form is investigated for mathematical consistency. We explore situations both analy…
Notes on oldest jump unravelling of spatial decoherence master equation
Gábor Homa, Lajos Diósi
Solution of free particle quantum master equation with spatial decoherence can be unravelled into stochastic quantum trajectories in many ways. The first example, published in 1985…
