High--order connected moments expansion for the Rabi Hamiltonian
High-order connected moments expansion Rabi Hamiltonian
font style='font-size:12px;'>
2010/11/9
We analyze the convergence properties of the connected moments expansion (CMX) for the Rabi Hamiltonian. To this end we calculate the moments and connected moments of the Hamiltonian operator to a suf...
Green's Function expansion of scalar and vector fields in the presence of a medium
Green's Function expansion scalar and vector fields presence of a medium
font style='font-size:12px;'>
2010/11/5
Based on a canonical approach and functional-integration techniques, a series expansion of Green's function of a scalar field, in the presence of a medium, is obtained. A series expansion for Lifshitz...

2010/10/20
We demonstrate an optical gate that increases the size of polarization-based W states by accessing only one of the qubits. Using this gate, we have generated three-photon and four-photon W states with...
On refined volatility smile expansion in the Heston model
smile expansion Heston model
font style='font-size:12px;'>
2010/4/27
It is known that Heston's stochastic volatility model exhibits moment explosion, and that the critical moment $s^{*}$ can be obtained by solving (numerically) a simple equation. This yields a leading ...
Spinning binary waveforms via PN expansion: Equal-mass case
binary waveforms post-Newtonian Equal-mass case
font style='font-size:12px;'>
2010/3/18
Complete expressions of time-domain gravitational waveforms for spinning binary inspirals via the post-Newtonian (PN) approximation would require determination of the phase, amplitude, inclination ang...
de Sitter expansion with anisotropic fluid in Bianchi type-I space-time
Bianchi type-I de Sitter expansion cosmological constant anisotropic fluid
font style='font-size:12px;'>
2010/3/17
Some features of the Bianchi type-I universes in the presence of a fluid that wields an anisotropic equation of state (EoS) parameter are discussed in the context of general relativity. The models tha...
hbar-expansion of KP hierarchy: Recursive construction of solutions
hbar-expansion KP hierarchy Planck constant
font style='font-size:12px;'>
2010/4/7
The \hbar-dependent KP hierarchy is a formulation of the KP hierarchy that depends on the Planck constant \hbar and reduces to the dispersionless KP hierarchy as \hbar -> 0. A recursive construction o...
The propagator for the step potential using the path decomposition expansion
propagator step potential path decomposition expansion
font style='font-size:12px;'>
2010/4/9
We present a direct path integral derivation of the propagator in the presence of a step potential. The derivation makes use of the Path Decomposition Expansion (PDX), and also of the definition of th...
Effective Width and Expansion Energy of the Interacting Condensed 87Rb Bose Gas with Finite Size Effects
Interacting Bose gas Thermodynamical properties for BEC Semiclassical approach
font style='font-size:12px;'>
2010/4/8
This work is devoted to study the temperature dependence of the effective width and expansion energy on the finite size and interaction effects (repulsive interactions). It is found that the effective...
