Quantum statistical mechanics in infinitely extended systems ( algebraic approach)
Shuichi Tasaki, Shigeru Ajisaka, Felipe Barra
The derivation of macroscopic irreversible dynamics of nonequilibrium systems from microscopic equations was recently revisited from the point of view of infinitely extended quantu…
Shear Modulus of an Elastic Solid under External Pressure as a function of Temperature: The case of Helium
Felipe Barra, Fernando Lund, Nicolás Mujica +1
The energy of a dislocation loop in a continuum elastic solid under pressure is considered within the framework of classical mechanics. For a circular loop, this is a function with…
Number of propagating modes of a diffusive periodic waveguide in the semiclassical limit
Felipe Barra, Agnes Maurel, Vincent Pagneux +1
We study the number of propagating Bloch modes N_B of an infinite periodic billiard chain. The asymptotic semiclassical behavior of this quantity depends on the phase-space dynamic…
Diffusive transport of waves in a periodic waveguide
Felipe Barra, Vincent Pagneux, Jaime Zuñiga
We study the propagation of waves in quasi-one-dimensional finite periodic systems whose classical (ray) dynamics is diffusive. By considering a random matrix model for a chain of…
