Phase shift in an atom interferometer induced by the additional laser lines of a Raman laser generated by modulation
atom interferometer additional laser lines of a Raman laser modulation Atomic Physics
2012/5/28
The use of Raman laser generated by modulation for light-pulse atom interferometer allows to have a laser system more compact and robust. However, the additional laser frequencies generated can pertur...
Structural phase transitions in multipole traps
Structural phase transitions multipole traps
2012/2/28
A small number of laser-cooled ions trapped in a linear radiofrequency multipole trap forms a hollow tube structure. We have studied, by means of molecular dynamics simulations, the structural transit...
Locking Local Oscillator Phase to the Atomic Phase via Weak Measurement
Locking Local Oscillator Atomic Phase Weak Measurement
2011/8/11
Abstract: We propose a new method to reduce the frequency noise of a Local Oscillator (LO) to the level of white phase noise by maintaining (not destroying by projective measurement) the coherence of ...

Carrier-envelope phase sensitive two-level systems
2011/9/2
We theoretically study the carrier-envelope phase dependent inversion generated in a two-level system by excitation with a few-cycle pulse. Based on the invariance of the inversion under time reversal...
Phase diagram of Rydberg atoms with repulsive van der Waals interaction
Phase diagram of Rydberg atoms
2011/9/14
We report a quantum Monte Carlo calculation of the phase diagram of bosons interacting with a repulsive inverse sixth power pair potential, a model for assemblies of Rydberg atoms in the local van der...
Stationary point approach to the phase transition of the classical XY chain with power law interactions
Stationary point power law interactions
2010/11/25
The stationary points of the Hamiltonian H of the classical XY chain with power law pair
interactions (i. e., decaying like r− with the distance) are analyzed. For a class of “spinwave-type”st...
Possible realization of the Exciton Bose Liquid phase in a hard-core boson model with ring-only exchange interactions
Possible realization ring-only exchange interactions
2010/11/17
We investigate a hard-core boson model with ring-only exchanges on a square lattice, where a K1
term acts on 1×1 plaquettes and a K2 term acts on 1×2 and 2×1 plaquettes, with a goal of realizing a no...
First Order Phase Transition of a Long Polymer Chain
First Order Phase Transition Long Polymer Chain
2010/11/17
We consider a model consisting of a self-avoiding polygon occupying a variable density of the sites of a square lattice. A fixed energy is associated with each 90◦-bend of the polygon. We use a ...
Phase transition to Bose-Einstein condensation for a Bosonic gas confined in a combined trap
Phase transition Bose-Einstein condensation Bosonic gas confined
2010/11/17
We present a study of phase transition to macroscopic superfluidity for an ultracold bosonic gas confined in a combined trap formed by a one-dimensional optical lattice and a harmonic potential, focu...
The dressed atom as binary phase modulator: towards attojoule/edge optical phase-shift keying
The dressed atom binary phase modulator
2010/11/16
Nanophotonic technologies offer great promise for ultra-low power optical signal processing, but relatively few nonlinear-optical phenomena have yet been explored as bases for robust digital modulati...
Phase diagram and critical endpoint for strongly-interacting quarks
Phase diagram critical endpoint strongly-interacting quarks
2011/1/6
We introduce a method based on the chiral susceptibility, which enables one to draw a phase diagram in the chemical-potential/temperature plane for strongly-interacting quarks whose interactions are d...
Decoherence due to an excited state quantum phase transition in a two-level boson model
Decoherence excited state quantum phase transition two-level boson model
2010/3/10
The decoherence induced on a single qubit by its interaction with the environment is studied. The environment is modelled as a scalar two-level boson system that can go through either first order or c...

Phase Distribution of the Output of Jaynes-Cummings Model with the Superposition of Squeezed Displaced Fock States
Non-classical field states squeezed displaced Fock states Wigner quasi-probability function phase distribution JCM
2010/4/9
The Wigner quasi-probability function for the superposition of squeezed displaced Fock states (SDFS's) is reviewed. The interaction of these states with a two-level atom in cavity with the presence of...
