Quantum fluctuation theorems and generalized measurements during the force protocol
Gentaro Watanabe, B. Prasanna Venkatesh, Peter Talkner +2
Generalized measurements of an observable performed on a quantum system during a force protocol are investigated and conditions that guarantee the validity of the Jarzynski equalit…
Comment on "Tsallis power laws and finite baths with negative heat capacity" [Phys. Rev. E 88, 042126 (2013)]
Michele Campisi
In [Phys. Rev. E 88, 042126 (2013)] it is stated that Tsallis distributions do not emerge from thermalization with a "bath" of finite, energy-independent, heat capacity. We report…
Employing Circuit QED to Measure Nonequilibrium Work Fluctuations
Michele Campisi, Ralf Blattmann, Sigmund Kohler +2
We study an interferometric method for the measurement of the statistics of work performed on a driven quantum system, which has been put forward recently [Dorner et al., Phys. Rev…
Quantum Fluctuation Relations for Ensembles of Wave Functions
Michele Campisi
New quantum fluctuation relations are presented. In contrast with the the standard approach, where the initial state of the driven system is described by the (micro)canonical densi…
Thermostated Hamiltonian dynamics with log-oscillators
Michele Campisi, Peter Hanggi
With this work we present two new methods for the generation of thermostated, manifestly Hamiltonian dynamics and provide corresponding illustrations. The basis for this new class…
Quantum Hertz entropy increase in a quenched spin chain
Darshan G. Joshi, Michele Campisi
The classical Hertz entropy is the logarithm of the volume of phase space bounded by the constant energy surface; its quantum counterpart, the quantum Hertz entropy, is $\hat S = k…
