Axiomatic construction of quantum Langevin equations
Rúbia Araújo, Sascha Wald, Malte Henkel
A phenomenological construction of quantum Langevin equations, based on the physical criteria of (i) the canonical equal-time commutators, (ii) the Kubo formula, (iii) the virial t…
Dynamical chaotic phases and constrained quantum dynamics
André M. Timpanaro, Sascha Wald, Fernando Semião +1
In classical mechanics, external constraints on the dynamical variables can be easily implemented within the Lagrangian formulation. Conversely, the extension of this idea to the q…
Dynamical off-equilibrium scaling across magnetic first-order phase transitions
Stefano Scopa, Sascha Wald
We investigate the off-equilibrium dynamics of a classical spin system with symmetry in spatial dimensions and in the limit . The system is set up in…
Energy barriers between metastable states in first order quantum phase transitions
Sascha Wald, Andre Timpanaro, Cecilia Cormick +1
A system of neutral atoms trapped in an optical lattice and dispersively coupled to the field of an optical cavity can realize a variation of the Bose-Hubbard model with infinite-r…
