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…
General spin and pseudospin symmetries of the Dirac equation
P. Alberto, M. Malheiro, T. Frederico +1
In the 70's Smith and Tassie, and Bell and Ruegg independently found SU(2) symmetries of the Dirac equation with scalar and vector potentials. These symmetries, known as pseudospin…
Nuclear symmetry energy in a modified quark meson coupling model
R. N. Mishra, H. S. Sahoo, P. K. Panda +2
We study nuclear symmetry energy and the thermodynamic instabilities of asymmetric nuclear matter in a self-consistent manner by using a modified quark-meson coupling model where t…
Core momentum distribution in two-neutron halo nuclei
Lucas A. Souza, Filipe F Bellotti, Marcelo T. Yamashita +2
The core momentum distribution of a weakly-bound neutron-neutron-core exotic nucleus is computed within a renormalized zero-range three-body model, with interactions in the s-wave…
Pion in the Medium with a Light-Front Model
J. P. B. C. de Melo, Kazuo Tsushima, Tobias Frederico
The pion properties in symmetric nuclear matter are investigated with the Quark-Meson Coupling (QMC) Model plus the light-front constituent quark model~(LFCQM). The LFCQM has been…
