On the zero-field orbital magnetic susceptibility of Bloch electrons in graphene-like solids: Some rigorous results
Diamagnetism zero-field susceptibility two-dimensional electrons gas graphene semiconductors
2012/4/17
Starting with a nearest-neighbors tight-binding model, we rigorously investigate the bulk zero-field orbital susceptibility of a non-interacting Bloch electrons gas in graphene-like solids at fixed te...

Observables axially symmetric space-times General Relativity and Quantum Cosmology
2011/10/10
Abstract: The periastron shift and the Lense-Thirring effect of bound orbital motion in a general axially symmetric space-time given by Pleba\'nski and Demia\'nski are analyzed. We also define a measu...

By considering the dynamical cluster approximation combined with the continuous time quantum
Monte Carlo algorithm, we analyze the behavior of a degenerate two-orbital anisotropic Hubbard
model at h...
Symmetry breaking orbital anisotropy on detwinned Ba(Fe1-xCox)2As2 above the spin density wave transition
Symmetry breaking orbital anisotropy detwinned Ba
2010/11/17
Nematicity, defined as broken rotational symmetry, has recently been observed in the competing phases in proximity to the superconducting phase in the high TC cuprates (1-2). Similarly, the new iron-b...
Rapidly fluctuating orbital occupancy above the orbital ordering transition in spin-gap compounds
Rapidly fluctuating orbital orbital ordering spin-gap compounds
2010/11/19
Several spin systems with low dimensionality develop a spin-dimer phase within a molecular orbital below TS, competing with long-range antiferromagnetic order. Very often, preferential orbital occupan...
Decoherence of orbital angular momentum entanglement in a turbulent atmosphere
Infinitesimal propagation equation entangle photons
2010/10/26
The evolution of an entangled photon state propagating through a turbulent atmosphere is formulated in terms of a set of coupled first order differential equations, by using an infinitesimal propagati...

Quantum Multiplexing Orbital Angular Momentum of light
2010/4/12
The orbital angular momentum, OAM, of photons offers a suitable support to carry the quantum data of multiple users. We present two novel optical setups that send the information of n quantum communic...
Collapses and revivals of stored orbital angular momentum of light in a cold atomic ensemble
Collapses orbital angular momentum light atomic ensemble
2010/4/8
We report on the storage of orbital angular momentum of light in a cold ensemble of cesium atoms. We employ Bragg diffraction to retrieve the stored optical information impressed into the atomic coher...

The Hubbard model for electrons with orbital degeneracy is shown to have an underlying SU_d(4) symmetry of spin-orbital double. A hidden charge SU_c(4) symmetry is exposed and an extended Lieb-Mattis ...
Orbital Period Modulation in Chromospherically Active Close Binaries
Orbital Period Modulation Chromospherically Active Close Binaries
2010/4/16
The orbital period changes in some chromospherically active close binaries have been interpreted as a consequence of magnetic activity. At least in two active close binaries a possible relationship be...
