Unitary equilibration after a quantum quench of a thermal state
N. Tobias Jacobson, Lorenzo Campos Venuti, Paolo Zanardi
In this work we investigate the equilibration dynamics after a sudden Hamiltonian quench of a quantum spin system initially prepared in a thermal state. To characterize the equilib…

Excitation transfer through open quantum networks: a few basic mechanisms
Lorenzo Campos Venuti, Paolo Zanardi
A variety of open quantum networks are currently under intense examination to model energy transport in photosynthetic systems. Here we study the coherent transfer of a quantum exc…

Optimal quasi-free approximation:reconstructing the spectrum from ground state energies
Lorenzo Campos Venuti
The sequence of ground state energy density at finite size, e_{L}, provides much more information than usually believed. Having at disposal e_{L} for short lattice sizes, we show h…
