Semiclassical Description of Relativistic Spin without use of Grassmann variables and the Dirac equation
Relativistic Spin Grassmann variables Dirac equation
2011/9/29
Abstract: We propose the relativistic particle model without Grassmann variables which, being canonically quantized, leads to the Dirac equation. Both $\Gamma$\,-matrices and the relativistic spin-ten...
A No-Go Theorem for the Consistent Quantization of the Massive Gravitino on Robertson-Walker Spacetimes and Arbitrary Spin 3/2 Fields on General Curved Spacetimes
No-Go Theorem the Consistent Quantization the Massive Gravitino Robertson-Walker Spacetimes General Curved Spacetimes
2011/7/29
Abstract: We first introduce a set of conditions which assure that a free spin $\frac32$ field with $m\ge 0$ can be consistently ('unitarily') quantized on all curved spacetimes, i.e. also on spacetim...
Elliptic gamma-function and multi-spin solutions of the Yang-Baxter equation
Elliptic gamma-function multi-spin solutions the Yang-Baxter equation
2011/7/27
Abstract: We present a generalization of the master solution to the quantum Yang-Baxter equation (obtained recently in arXiv:1006.0651) to the case of multi-component continuous spin variables taking ...
Orientation-to-alignment conversion and spin squeezing
Orientation-to-alignment conversion spin squeezing
2011/9/2
The relationship between orientation-to-alignment conversion (a form of atomic polarization evolution induced by an electric eld) and the phenomenon of spin squeezing is demonstrated. A \stretched" s...

Extended supersymmetry massless conformal higher spin theory Mathematical Physics
2011/7/28
Abstract: We propose superfield equations in tensorial N-extended superspaces to describe the N=2,4,8 supersymmetric generalizations of free conformal higher spin theories. These can be obtained by qu...

Spin Networks Braided Ribbon Networks General Relativity and Quantum Cosmology
2011/7/26
Abstract: We connect Braided Ribbon Networks to the states of loop quantum gravity. Using this connection we present the reduced link as an invariant which captures information from the embedding of t...

Magnetocardiography with a modular spin-exchange relaxation free atomic magnetometer array
Instrumentation and measurement, Atomic and molecular physics, Medical physics, Biological physics
2011/9/6
We present a portable four-channel atomic magnetometer array operating in the spin exchange relaxation-free regime. The magnetometer array has several design
features intended to maximize its suitabi...
Integrable relativistic systems given by Hamiltonians with momentum-spin-orbit coupling
Integrable relativistic systems Hamiltonians momentum-spin-orbit coupling
2011/7/26
Abstract: In the paper we investigate the evolution of the relativistic particle (massive and massless) with spin defined by Hamiltonian containing the terms with momentum-spin-orbit coupling. We inte...
Canonical Formulation of Spin in General Relativity
Dissertation canonical formalism spin post-Newtonian approximation binary stars
2011/7/28
Abstract: The present thesis aims at an extension of the canonical formalism of Arnowitt, Deser, and Misner from self-gravitating point-masses to objects with spin. This would allow interesting applic...
Abstract: Gibbs' measures in the Sherrington-Kirkpatrick type models satisfy two asymptotic stability properties, the Aizenman-Contucci stochastic stability and the Ghirlanda-Guerra identities, which ...
Spin Hall effect of light in metallic reflection

2011/8/31
We report the first measurement of the Spin Hall Effect of Light (SHEL) on an air-metal interface. The SHEL is a polarization-dependent out-of-plane shift on the reflected beam. For the case of metall...

2011/8/31
We investigate theoretically the long-range electrostatic interactions between a ground-state homonuclear alkali-metal dimer and an excited alkali-metal atom taking into account its fine-structure. Th...
Ultracold spin-polarized mixtures of 2Sigma molecules with S-state atoms: Collisional stability and implications for sympathetic cooling
S-state atoms physics and chemistry molecular
2011/8/31
The prospects of sympathetic cooling of polar molecules with magnetically co-trapped alkalimetal atoms are generally considered poor due to strongly anisotropic atom-molecule interactions leading to l...
Role of Azimuthal Energy Flows in the Geometric Spin Hall Effect of Light
Light beam Circular polarization Oblique incidence Lateral shift Transverse energy flow Angular momentum
2011/8/29
In an oblique section of a paraxial beam with angular momentum, the beam center of gravity (CG) is shifted with respect to its position in the normal cross section. We relate this shift with the inter...
