Boltzmann counting in Hilbert space
Raúl O. Vallejos, Isadora Veeren, Frederico Brito +1
We introduce a geometric entropy for quantum preparations, defined as the logarithm of the Hilbert-space volume of pure states compatible with a given set of constraints. This cons…
Energy additivity as a requirement for universal quantum thermodynamical frameworks
Luis Rodrigo Neves, Frederico Brito
The quest to develop a general framework for thermodynamics, suitable for the regime of strong coupling and correlations between subsystems of an autonomous quantum "universe," has…
Experimental Investigation of Geometric Quantum Speed Limits in an Open Quantum System
Diego Paiva Pires, Eduardo R. deAzevedo, Diogo O. Soares-Pinto +2
We studied geometric quantum speed limits (QSL) of a qubit subject to decoherence in an ensemble of chloroform molecules in a Nuclear Magnetic Resonance experiment. The QSL is a fu…
A Schmidt decomposition approach to quantum thermodynamics
André Malavazi, Frederico Brito
The development of a self-consistent thermodynamic theory of quantum systems is of fundamental importance for modern physics. Still, despite its essential role in quantum science a…
A constraint on local definitions of quantum internal energy
Luis Rodrigo Torres Neves, Frederico Brito
Recent advances in quantum thermodynamics have been focusing on ever more elementary systems of interest, approaching the limit of a single qubit, with correlations, strong couplin…
Emergence of energy-avoiding and energy-seeking behaviours in nonequilibrium dissipative quantum systems
Thiago Werlang, Maurício Matos, Frederico Brito +1
A longstanding challenge in nonequilibrium thermodynamics is to predict the emergence of self-organized behaviours and functionalities typical of living matter. Despite the progres…
