Joint fluctuation theorems for sequential heat exchange
Jader P. Santos, André M. Timpanaro, Gabriel T. Landi
We study the statistics of heat exchange of a quantum system that collides sequentially with an arbitrary number of ancillas. This can describe, for instance, an accelerated partic…
Landauer's principle at zero temperature
Andre M. Timpanaro, Jader P. Santos, Gabriel T. Landi
Landauer's bound relates changes in the entropy of a system with the inevitable dissipation of heat to the environment. The bound, however, becomes trivial in the limit of zero tem…
Thermodynamic uncertainty relations from exchange fluctuation theorems
André M. Timpanaro, Giacomo Guarnieri, John Goold +1
Thermodynamic uncertainty relations (TURs) place strict bounds on the fluctuations of thermodynamic quantities in terms of the associated entropy production. In this work we identi…
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…
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…
