Noncanonical statistics of a spin-boson model: Theory and exact Monte Carlo simulations
Non Canonical statistics a spin-boson model Theory exact Monte Carlo simulations
2014/9/24
Equilibrium canonical distribution in statistical mechanics assumes weak system-bath coupling (SBC). In real physical situations this assumption can be invalid, and equilibrium quantum statistics of t...

Width of Phonon Sidebands Brownian Oscillator Model
2014/9/24
The line width dependence of zero-phonon lines and phonon sidebands on temperature, bath dissipation, and electron-phonon coupling is studied for an underdamped Brownian oscillator model with an Ohmic...
East Model: Basis Set Expansion, Mode Coupling, and Irreducible Memory Kernels
East Model Basis Set Expansion Mode Coupling Irreducible Memory Kernels
2014/9/24
A matrix formalism defined in the complete dynamic phase space is developed to analyze spin relaxation in the East model and the dynamic slow-down of dissipative systems in general. The truncated basi...
