Ergodicity breaking and deviation from Eigenstate Thermalisation in relativistic QFT
Miha Srdinšek, Tomaž Prosen, Spyros Sotiriadis
The validity of the ergodic hypothesis in quantum systems can be rephrased in the form of the eigenstate thermalisation hypothesis (ETH), a set of statistical properties for the ma…
Rényi entropy of quantum anharmonic chain at non-zero temperature
Miha Srdinšek, Michele Casula, Rodolphe Vuilleumier
The interplay of quantum and classical fluctuations in the vicinity of a quantum critical point (QCP) gives rise to various regimes or phases with distinct quantum character. In th…
Quantum Rényi entropy by optimal thermodynamic integration paths
Miha Srdinšek, Michele Casula, Rodolphe Vuilleumier
Despite being a well-established operational approach to quantify entanglement, Rényi entropy calculations have been plagued by their computational complexity. We introduce here a…
Adiabatic motion and statistical mechanics via mass zero constrained dynamics
Sara Bonella, Alessandro Coretti, Rodolphe Vuilleumier +1
In recent work [Coretti et al., The Journal of Chemical Physics, 2018, 149, 191102], a new algorithm to solve numerically the dynamics of the shell model for polarization was prese…
Solvation free-energy pressure corrections in the Three Dimensional Reference Interaction Site Model
Volodymyr Sergiievskyi, Guillaume Jeanmairet, Maximilien Levesque +1
Solvation free energies are efficiently predicted by molecular density functionnal theory (MDFT) if one corrects the overpressure introduced by the usual homogeneous reference flui…
