Exact Work Characteristic Functions for Time-Dependent Bosonic Quadratic Hamiltonians
F. Nicacio, R. N. P. Maia
We derive an exact analytical expression for the characteristic function of work in closed many-body bosonic systems governed by general time-dependent quadratic Hamiltonians. This…
Thermal equilibrium in Gaussian dynamical semigroups
Fabricio Toscano, Fernando Nicacio
We characterize all Gaussian dynamical semigroups in continuous variables quantum systems of n-bosonic modes which have a thermal Gibbs state as a stationary solution. This is perf…
Gauge Quantum Thermodynamics of Time-local non-Markovian Evolutions
Fernando Nicacio, Raphael N. P. Maia
Dealing with a generic time-local non-Markovian master equation, we define current and power to be process-dependent as in classical thermodynamics. Each process is characterized b…
Williamson theorem in classical, quantum, and statistical physics
F. Nicacio
In this work we present (and encourage the use of) the Williamson theorem and its consequences in several contexts in physics. We demonstrate this theorem using only basic concepts…
Weyl-Wigner Representation of Canonical Equilibrium States
F. Nicacio
The Weyl-Wigner representations for canonical thermal equilibrium quantum states are obtained for the whole class of quadratic Hamiltonians through a Wick rotation of the Weyl-Wign…
Mean Value of the Quantum Potential and Uncertainty Relations
F. Nicacio, F. T. Falciano
In this work we determine a lower bound to the mean value of the quantum potential for an arbitrary state. Furthermore, we derive a generalized uncertainty relation that is stronge…
