Transport in a disordered tight-binding chain with dephasing
Marko Znidaric, Martin Horvat
We study transport properties of a disordered tight-binding model (XX spin chain) in the presence of dephasing. Focusing on diffusive behavior in the thermodynamic limit at high en…
Optimal number of pigments in photosynthetic complexes
Simon Jesenko, Marko Znidaric
We study excitation energy transfer in a simple model of photosynthetic complex. The model, described by Lindblad equation, consists of pigments interacting via dipole-dipole inter…
Diffusive high-temperature transport in the one-dimensional Hubbard model
Tomaz Prosen, Marko Znidaric
We consider charge and spin transport in the one-dimensional Hubbard model at infinite temperature, half-filling and zero magnetization. Implementing matrix-product-operator simula…
Entanglement in stationary nonequilibrium states at high energies
Marko Znidaric
In recent years it has been found that quantum systems can posses entanglement in equilibrium thermal states provided temperature is low enough. In the present work we explore a po…
