Energy fluctuations in a randomly driven granular fluid
M. I. Garcia de Soria, P. Maynar, E. Trizac
We study the behavior of the energy fluctuations in the stationary state of a uniformly heated granular gas. The equation for the one-time two-particle correlation function is deri…
Scaling and aging in the homogeneous cooling state of a granular fluid of hard particles
J. J. Brey, A. Prados, M. I. Garcia de Soria +1
The presence of the aging phenomenon in the homogeneous cooling state (HCS) of a granular fluid composed of inelastic hard spheres or disks is investigated. As a consequence of the…
Microcanonical quantum fluctuation theorems
Peter Talkner, Peter Hanggi, Manuel Morillo
Previously derived expressions for the characteristic function of work performed on a quantum system by a classical external force are generalized to arbitrary initial states of th…
Thermal equilibrium and statistical thermometers in special relativity
David Cubero, Jesús Casado-Pascual, Jörn Dunkel +2
There is an intense debate in the recent literature about the correct generalization of Maxwell's velocity distribution in special relativity. The most frequently discussed candida…
Transport Coefficients for the Hard Sphere Granular Fluid
Aparna Baskaran, James W. Dufty, J. Javier Brey
In the preceding paper, linear response methods have been applied to obtain formally exact expressions for the parameters of Navier-Stokes order hydrodynamics. The analysis there i…
Continuous unitary transformations in two-level boson systems
S. Dusuel, J. Vidal, J. M. Arias +2
Two-level boson systems displaying a quantum phase transition from a spherical (symmetric) to a deformed (broken) phase are studied. A formalism to diagonalize Hamiltonians with $O…
