Generalized Purity and Quantum Phase Transition for Bose-Einstein condensates in a Symmetric Double Well
Thiago F. Viscondi, K. Furuya, M. C. de Oliveira
The generalized purity is employed for investigating the process of coherence loss and delocalization of the Q-function in the Bloch sphere of a two-mode Bose-Einstein condensate i…
Entanglement and the Mott insulator - superfluid phase transition in bosonic atom chains
R. J. Costa Farias, M. C. de Oliveira
We analyze the developing of bipartite and multipartite entanglement through the Mott-Insulator - Superfluid quantum phase transition. Starting from a Mott insulator state, where a…
Test of Chemical freeze-out at RHIC
Jun Takahashi
We present the results of a systematic test applying statistical thermal model fits in a consistent way for different particle ratios, and different system sizes using the various…
Sub-terahertz, microwaves and high energy emissions during the December 6, 2006 flare, at 18:40 UT
Pierre Kaufmann, Gerard Trottet, C. Guillermo Gimenez de Castro +4
The presence of a solar burst spectral component with flux density increasing with frequency in the sub-terahertz range, spectrally separated from the well-known microwave spectral…
Inner and outer edge states in graphene rings: A numerical investigation
D. A. Bahamon, A. L. C. Pereira, P. A. Schulz
We numerically investigate quantum rings in graphene and find that their electronic properties may be strongly influenced by the geometry, the edge symmetries and the structure of…
Sharp error terms for return time statistics under mixing conditions
Miguel Abadi, Nicolas Vergne
We describe the statistics of repetition times of a string of symbols in a stochastic process. Denote by T(A) the time elapsed until the process spells the finite string A and by S…
Rapid pulsations in sub-THz solar bursts
Pierre Kaufmann, C. Guillermo Gimenez de Castro, Emilia Correia +3
A new solar burst emission spectral component has been found showing sub-THz fluxes increasing with frequency, spectrally separated from the well known microwave component. Rapid p…
Observation of Two-source Interference in the Photoproduction Reaction
B. I. Abelev
In ultra-peripheral relativistic heavy-ion collisions, a photon from the electromagnetic field of one nucleus can fluctuate to a quark-antiquark pair and scatter from the other nuc…
Graphene in the Quantum Hall Regime: Effects of Vacancies, Sublattice Polarization and Disorder
Ana L. C. Pereira, Peter A. Schulz
We investigate the effects of vacancies, disorder and sublattice polarization on the electronic properties of a monolayer graphene in the quantum Hall regime. Energy spectra as a f…
Stability of Orbits around a Spinning Body in a Pseudo-Newtonian Hill Problem
A. F. Steklain, P. S. Letelier
A pseudo-Newtonian Hill problem based on a potential proposed by Artemova et al. [Astroph. J. 461 (1996) 565] is presented. This potential reproduces some of the general relativist…
Direct determination of the crystal field parameters of Dy, Er and Yb impurities in the skutterudite compound CeFeP by Electron Spin Resonance
D. J. Garcia, F. A. Garcia, J. G. S. Duque +5
Despite extensive research on the skutterudites for the last decade, their electric crystalline field ground state is still a matter of controversy. We show that Electron Spin Reso…
Energy-resolved spatial inhomogeneity of disordered Mott systems
E. C. Andrade, E. Miranda, V. Dobrosavljevic
We investigate the effects of weak to moderate disorder on the T=0 Mott metal-insulator transition in two dimensions. Our model calculations demonstrate that the electronic states…
Possible scenario for MaVaN's as the only neutrino flavor conversion mechanism in the Sun
Pedro Cunha de Holanda
Mass Varying neutrino mechanisms were proposed to link the neutrino mass scale with dark energy, addressing the coincidence problem. In some scenarios this mass can present a depen…
Robust Network Coding in the Presence of Untrusted Nodes
Da Wang, Danilo Silva, Frank R. Kschischang
While network coding can be an efficient means of information dissemination in networks, it is highly susceptible to "pollution attacks," as the injection of even a single erroneou…
Non-Gaussian two-mode squeezing and continuous variable entanglement of linearly and circularly polarized light beams interacting with cold atoms
R. J. Missori, M. C. de Oliveira, K. Furuya
We investigate how entangled coherent states and superpositions of low intensity coherent states of non-Gaussian nature can be generated via non-resonant interaction between either…
Coherent state approach to the cross collisional effects in the population dynamics of a two-mode Bose-Einstein condensate
Thiago F. Viscondi, K. Furuya, M. C. de Oliveira
We reanalyze the non-linear population dynamics of a Bose-Einstein Condensate (BEC) in a double well trap considering a semiclassical approach based on a time dependent variational…
Probing New Limits for the Violation of the Equivalence Principle in the solar-reactor neutrino sector as a next to leading order effect
G. A. Valdiviesso, M. M. Guzzo, P. C. Holanda
New limits for the Violation of Equivalence Principle (VEP) are obtained considering the mass-flavor mixing hypothesis. This analysis includes observations of solar and reactor neu…
Survival of branching random walks in random environment
Nina Gantert, Sebastian Müller, Serguei Popov +1
We study survival of nearest-neighbour branching random walks in random environment (BRWRE) on . A priori there are three different regimes of survival: global surviva…
Energy and system size dependence of ϕmeson production in Cu+Cu and Au+Au collisions
STAR Collaboration
We study the beam-energy and system-size dependence of ϕmeson production (using the hadronic decay mode ϕ-- K+K-) by comparing the new results from Cu+Cu collisions and previously…
Vanishing viscosity limit for an expanding domain in space
