Quantum Dynamics in Noisy Backgrounds: from sampling to dissipation and fluctuations
O. Oliveira, W. de Paula, T. Frederico +1
We investigate the dynamics of a quantum system coupled linearly to Gaussian white noise using functional methods. By performing the integration over the noisy field in the evoluti…
Two Dimensional Honeycomb Materials: random fields, dissipation and fluctuations
T. Frederico, O. Oliveira, W. de Paula +2
In this paper, we propose a method to describe the many-body problem of electrons in honeycomb materials via the introduction of random fields which are coupled to the electrons an…
Quantum Field Theory Approach to the Optical Conductivity of Strained and Deformed Graphene
W. de Paula, a. Chaves, O. Oliveira +1
The computation of the optical conductivity of strained and deformed graphene is discussed within the framework of quantum field theory in curved spaces. The analytical solutions o…
Cosmological and Particle Physics Constraints on a New Non-Abelian SU(3) Gauge Model for Ordinary/Dark Matter Interaction
O. Oliveira, C. A. Bertulani, M. S. Hussein +2
We propose a mirror model for ordinary and dark matter that assumes a new SU(3) gauge group of transformations, as a natural extension of the Standard Model (SM). A close study of…
