Long timescale dynamics spin textures Rb spinor Bose gas
2011/8/17
Abstract: We investigate the long-term dynamics of spin textures prepared by cooling unmagnetized spinor gases of F=1 $^{87}$Rb to quantum degeneracy, observing domain coarsening and a strong dependen...
A New Proposal for the Picture Changing Operators in the Minimal Pure Spinor Formalism
New Proposal the Minimal Pure Spinor Formalism High Energy Physics - Theory
2011/7/27
Abstract: Using a new proposal for the "picture lowering" operators, we compute the tree level scattering amplitude in the minimal pure spinor formalism by performing the integration over the pure spi...

Fuzzy Geometry the Spinor Bundle Holographic Space-time Matrix Theory
2011/7/27
Abstract: We present a new framework for defining fuzzy approximations to geometry in terms of a cutoff on the spectrum of the Dirac operator, and a generalization of it that we call the Dirac-Flux op...

2010/12/23
The tree-level amplitude of six massless open strings is computed using the pure spinor formalism. The OPE poles among integrated and unintegrated vertices can be efficiently organized according to th...

Spatial spinor Bose-Einstein condensates
2010/11/24
We investigate the St¨uckelberg oscillations of a spin-1 Bose-Einstein condensate subject to a
spatially inhomogeneous transverse magnetic field and a periodic longitudinal field. We show that the ti...

Quantum rotor theory of spinor condensates tight traps
2010/11/23
In this work, we theoretically construct exact mappings of many-particle bosonic systems onto
quantum rotor models. In particular, we analyze the rotor representation of spinor Bose-Einstein condensa...
Spontaneously axisymmetry breaking phase in a binary mixture of spinor Bose-Einstein condensates
Spontaneously axisymmetry spinor Bose-Einstein condensates
2010/11/17
We study the ground state phases for a mixture of two atomic spin-1 Bose-Einstein condensates
(BECs) in the presence of a weak magnetic (B-) field. The ground state is found to contain a
broken-axis...

Phase space spinor amplitudes spin 1/2 systems
2010/11/5
The concept of phase space amplitudes for systems with continuous degrees of freedom is generalized to finite-dimensional spin systems. Complex amplitudes are obtained on both a sphere and a finite la...

2010/11/5
We propose a scheme for the realization of a quantum walker and a quantum simulator for the Dirac equation with ultracold spinor atoms in driven optical lattices. A precise control of the dynamics of ...

2010/4/13
We report on the spin textures produced by cooling unmagnetized $^{87}$Rb F=1 spinor gases into the regime of quantum degeneracy. At low temperatures, magnetized textures form that break translational...
