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…

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…

Phase Space Structure of Generalized Gaussian Cat States
Fernando Nicacio, Raphael N. P. Maia, Fabricio Toscano +1
We analyze generalized Gaussian cat states obtained by superposing arbitrary Gaussian states, e.g., a coherent state and a squeezed state. The Wigner functions of such states exhib…
