Variational ground-state quantum adiabatic theorem
Bojan Žunkovič, Pietro Torta, Giovanni Pecci +2
We present a variational quantum adiabatic theorem, which states that, under certain assumptions, the adiabatic dynamics projected onto a variational manifold follow the instantane…
Nonequilibrium Quantum Phase Transitions in the XY model: comparison of unitary time evolution and reduced density matrix approaches
Shigeru Ajisaka, Felipe Barra, Bojan Žunkovič
We study nonequilibrium quantum phase transitions in XY spin 1/2 chain using the algebra. We show that the well-known quantum phase transition at magnetic field persi…
Quantum group approach to steady states of boundary-driven open quantum systems
Enej Ilievski, Bojan Žunkovič
We present a systematic approach for constructing steady state density operators of Markovian dissipative evolution for open quantum chain models with integrable bulk interaction a…
Transport properties of a boundary-driven one-dimensional gas of spinless fermions
Marko Znidaric, Bojan Zunkovic, Tomaz Prosen
We analytically study a system of spinless fermions driven at the boundary with an oscillating chemical potential. Various transport regimes can be observed: at zero driving freque…
Exact solution of Markovian master equations for quadratic fermi systems: thermal baths, open XY spin chains, and non-equilibrium phase transition
Tomaz Prosen, Bojan Zunkovic
We generalize the method of third quantization to a unified exact treatment of Redfield and Lindblad master equations for open quadratic systems of n fermions in terms of diagonali…
