Persistent current on a disordered mesoscopic ring with an embedded quantum dot
E. H. Martins Ferreira, M. C. Nemes, H. A. Weidenmueller
We calculate the ensemble averaged persistent current on disordered mesoscopic rings with an embedded quantum dot. We model the quantum dot as a single resonance and use Random Mat…
Dispersion and uncertainty in multislit matter wave diffraction
G. Glionna, A. H. Blin, B. Hiller +3
We show that single and multislit experiments involving matter waves may be constructed to assess correlations between the position and momentum of a single free particle. These co…
Arbitrary parameters in implicit regularization and democracy within perturbative description of 2-dimensional gravitational anomalies
Leonardo A. M. Souza, Marcos Sampaio, M. C. Nemes
We show that the Implicit Regularization Technique is useful to display quantum symmetry breaking in a complete regularization independent fashion. Arbitrary parameters are express…
Implicit Regularization and Renormalization of QCD
M. D. Sampaio, A. P. B. Scarpelli, J. E. Ottoni +1
We apply the Implicit Regularization Technique (IR) in a non-abelian gauge theory. We show that IR preserves gauge symmetry as encoded in relations between the renormalizations con…
Quantum Entanglement and fixed point Hopf bifurcation
M. C. Nemes, K. Furuya, G. Q. Pellegrino +3
We present the qualitative differences in the phase transitions of the mono-mode Dicke model in its integrable and chaotic versions. We show that a first order phase transition occ…
Decoherence and localization in the double well model
Gabriela Barreto Lemos, M. F. Santos, J. G. Peixoto de Faria +2
We use a spin-1/2 model to analyze tunnelling in a double well system coupled to an external reservoir. We consider different noise sources such as fluctuations on the height and c…
