Dynamics of Loschmidt echoes and fidelity decay

- T. Gorin, T. Prosen, T. Seligman, M. Znidaric
- Physics
- 7 July 2006

Fidelity serves as a benchmark for the reliability in quantum information processes, and has recently attracted much interest as a measure of the susceptibility of dynamics to perturbations. A rich… Expand

Many-body localization in the Heisenberg XXZ magnet in a random field

- M. Znidaric, T. Prosen, P. Prelovšek
- Physics
- 18 June 2007

We numerically investigate Heisenberg XXZ spin-1/2 chain in a spatially random static magnetic field. We find that tDMRG simulations of time evolution can be performed efficiently, namely the… Expand

Stability of quantum motion and correlation decay

- T. Prosen, M. Znidaric
- Physics
- 6 November 2001

We derive a simple and general relation between the fidelity of quantum motion, characterizing the stability of quantum dynamics with respect to arbitrary static perturbation of the unitary evolution… Expand

Is the efficiency of classical simulations of quantum dynamics related to integrability?

- T. Prosen, M. Znidaric
- Physics, MedicinePhysical review. E, Statistical, nonlinear, and…
- 7 August 2006

Efficiency of time evolution of quantum observables, and thermal states of quenched Hamiltonians, is studied using time-dependent density-matrix renormalization group method in a family of generic… Expand

Exact solution for a diffusive nonequilibrium steady state of an open quantum chain

- M. Znidaric
- Physics, Mathematics
- 7 May 2010

We calculate a nonequilibrium steady state of a quantum XX chain in the presence of dephasing and driving due to baths at chain ends. The obtained state is exact in the limit of weak driving while… Expand

Charge and spin transport in strongly correlated one-dimensional quantum systems driven far from equilibrium

- G. Benenti, G. Casati, T. Prosen, D. Rossini, M. Znidaric
- Physics
- 14 January 2009

We study the charge conductivity in one-dimensional prototype models of interacting particles, such as the Hubbard and the $t\text{\ensuremath{-}}V$ spinless fermion models, when coupled to some… Expand

Finite-temperature transport in one-dimensional quantum lattice models

- B. Bertini, F. Heidrich-Meisner, C. Karrasch, T. Prosen, R. Steinigeweg, M. Znidaric
- Physics
- 6 March 2020

The last decade has witnessed an impressive progress in the theoretical understanding of transport properties of clean, one-dimensional quantum lattice systems. Many physically relevant models in one… Expand

Subsystem dynamics under random Hamiltonian evolution

- Vinayak, M. Znidaric
- Physics, Mathematics
- 29 July 2011

We study time evolution of a subsystem's density matrix under unitary evolution, generated by a sufficiently complex, say quantum chaotic, Hamiltonian, modeled by a random matrix. We exactly… Expand
