A precise formulation of the third law of thermodynamics
Walter F. Wreszinski, Elcio Abdalla
The third law of thermodynamics is formulated precisely: all points of the state space of zero temperature are physically adiabatically inaccessible from the state space of a…
An analytical relation between entropy production and quantum Lyapunov exponents for Gaussian bipartite systems
K. M. Fonseca Romero, J. E. Parreira, L. A. M. Souza +2
We study and compare the information loss of a large class of Gaussian bipartite systems. It includes the usual Caldeira-Leggett type model as well as Anosov models (parametric osc…
Quantum NOT Operation and Integrability in Two-Level Systems
Renato M. Angelo, Walter F. Wreszinski
We demonstrate the surprising integrability of the classical Hamiltonian associated to a spin 1/2 system under periodic external fields. The one-qubit rotations generated by the dy…
Onsager's Inequality, the Landau-Feynman Ansatz and Superfluidity
W. F. Wreszinski, M. A. da Silva
We revisit an inequality due to Onsager, which states that the (quantum) liquid structure factor has an upper bound of the form (const.) x |k|, for not too large modulus of the wav…
