Asymmetric environment induces protein-like relaxation in spin chain
Daniel Valente, Thiago Werlang
Proteins are aminoacid chains that diffusively fold or unfold depending on the thermal and chemical environmental conditions. While sophisticated models account for detailed aspect…
Casimir effect and Stefan-Boltzmann law in Yang-Mills theory at finite temperature
A. F. Santos, Faqir C. Khanna
A non-Abelian gauge theory describes the strong interactions among particles with the commutator of generators are non-zero. An gauge theory describes the interactions that…
Non-abelian gauge symmetry for fields in phase space: a realization of the Seiberg-Witten non-abelian gauge theory
J. S. Cruz-Filho, R. G. G. Amorim, F. C. Khanna +3
The Seiberg-Witten formalism has been realized as an electrodynamics in phase space (associated to the Dirac equation written in phase space) and this fact is explored here with no…
Multipartite States under Elementary Local Operations
F. E. S. Steinhoff
Multipartite pure states are equivalent under Stochastic Local Operations and Classical Communication (SLOCC) whenever they can be mapped into one another by Invertible Local Opera…
On Gravitational Casimir Effect and Stefan-Boltzmann Law at Finite Temperature
S. C. Ulhoa, A. F. Santos, T. F. Furtado +1
Gravitons are described by the propagator in Teleparallel gravity in nearly flat space-time. Finite temperature is introduced by using Thermo Field Dynamics formalism. The Gravitat…
Instability of Reissner-Nordström-AdS black hole under perturbations of a scalar field coupled to Einstein tensor
E. Abdalla, B. Cuadros-Melgar, R. D. B. Fontana +3
We study the instability of a Reissner-Nordström-AdS (RNAdS) black hole under perturbations of a massive scalar field coupled to Einstein tensor. Calculating the potential of the s…
Ricci dark energy in bumblebee gravity model
W. D. R. Jesus, A. F. Santos
The Ricci dark energy is a model inspired by the holographic dark energy models with the dark energy density being proportional to Ricci scalar curvature. Here this model is studie…
Mach-Zehnder interferometer with quantum beamsplitters
Nelson Almeida, Thiago Werlang, Daniel Valente
A one-dimensional waveguide enables a single two-level emitter to route the propagation of a single photon, as to provide a quantum mirror or a quantum beamsplitter. Here we presen…
On Lorentz violation in scattering at finite temperature
P. R. A. Souza, A. F. Santos, S. C. Ulhoa +1
Small violation of Lorentz and CPT symmetries may emerge in models unifying gravity with other forces of nature. An extension of the standard model with all possible terms that vio…
Lorentz violation and Gravitoelectromagnetism: Casimir effect and Stefan-Boltzmann law at Finite temperature
A. F. Santos, Faqir C. Khanna
The standard model and general relativity are local Lorentz invariants. However it is possible that at Planck scale there may be a breakdown of Lorentz symmetry. Models with Lorent…
