A Langevin canonical approach to the dynamics of chiral two level systems. Thermal averages and heat capacity
H. C. Peñate-Rodríguez, A. Dorta-Urra, P. Bargueño +2
A Langevin canonical framework for a chiral two--level system coupled to a bath of harmonic oscillators is developed within a coupling scheme different to the well known spin-boson…
A Langevin canonical approach to the dynamics of two level systems. I. Populations and coherences
H. C. Peñate-Rodriguez, A. Dorta-Urra, P. Bargueno +2
A canonical framework for chiral two--level systems coupled to a bath of harmonic oscillators is developed to extract, from a stochastic dynamics, the thermodynamic equilibrium val…
Quantum Zeno and anti-Zeno effects in surface diffusion of interacting adsorbates
H. C. Pennate-Rodriguez, R. Martinez-Casado, G. Rojas-Lorenzo +2
Surface diffusion of interacting adsorbates is here analyzed within the context of two fundamental phenomena of quantum dynamics, namely the quantum Zeno effect and the anti-Zeno e…
Linear response theory of activated surface diffusion with interacting adsorbates
R. Martinez-Casado, A. S. Sanz, J. L. Vega +2
Activated surface diffusion with interacting adsorbates is analyzed within the Linear Response Theory framework. The so-called interacting single adsorbate model is justified by me…
Two-bath model for activated surface diffusion of interacting adsorbates
R. Martinez-Casado, A. S. Sanz, G. Rojas-Lorenzo +1
The diffusion and low vibrational motions of adsorbates on surfaces can be well described by a purely stochastic model, the so-called interacting single adsorbate model, for low-mo…
Basis of a non Riemannian Geometry within the Equilibrium Thermodynamics
L. Velazquez, F. Guzman
Microcanonical description is characterized by the presence of an internal symmetry closely related with the dynamical origin of this ensemble: the reparametrization invariance. Su…
