Transient state work fluctuation theorem for a classical harmonic oscillator linearly coupled to a harmonic bath

Variational treatment of a harmonic oscillator coupled to a dissipative heat bath

Work fluctuation theorems for harmonic oscillators.

The work fluctuations of an oscillator in contact with a thermostat and driven out of equilibrium by an external force are studied experimentally and theoretically within the context of fluctuation theorems. The oscillator dynamics is modeled by a second order Langevin equation. Both the transient and stationary state fluctuation theorems hold and the finite time corrections are very different ...

Vibrational spectroscopy and relaxation of an anharmonic oscillator coupled to harmonic bath.

The vibrational spectroscopy and relaxation of an anharmonic oscillator coupled to a harmonic bath are examined to assess the applicability of the time correlation function (TCF), the response function, and the semiclassical frequency modulation (SFM) model to the calculation of infrared (IR) spectra. These three approaches are often used in connection with the molecular dynamics simulations bu...

Calorimetric measurement of work for a driven harmonic oscillator.

A calorimetric measurement has recently been proposed as a promising technique to measure thermodynamic quantities in a dissipative superconducting qubit. These measurements rely on the fact that the system is projected into energy eigenstates whenever energy is exchanged with the environment. This requirement imposes a restriction on the class of systems that can be measured in this way. Here ...

Decoherence and relaxation of a qubit coupled to a Ohmic bath directly and via a intermediate harmonic oscillator

Solid state qubits are considered to be promising candidates for realizing building blocks of quantum information processors. Many researches on the decoherence, relaxation and manipulation of qubits not only theoretically but also experimentally have been performed. Most of these researches are based on a spin boson (SB) model which is supposed being constructed with a spin (qubit or two-level...
