The Role of Collective Neutrino Flavor Oscillations in Core-Collapse Supernova Shock Revival
Core-Collapse Supernova Shock Revival Neutrino
2011/7/21
We explore the effects of collective neutrino flavor oscillations due to neutrino-neutrino interactions on the neutrino heating behind a stalled core-collapse supernova shock. We carry out axisymmetri...
Convergence of repeated QND measurements and the wave function collapse
QND measurement the wave function collapse Quantum Physics
2011/7/26
Abstract: Motivated by recent experiments on quantum trapped fields, we give a rigorous proof that repeated indirect quantum non-demolition (QND) measurements converge to the collapse of the wave func...
Voltage Collapse and ODE Approach to Power Flows: Analysis of a Feeder Line with Static Disorder in Consumption/Production
Voltage Collapse Consumption/Production Feeder Line Static Disorder
2011/9/15
We consider a model of a distribution feeder connecting multiple loads to the sub-station. Voltage is controlled directly at the head of the line (sub-station), however,voltage anywhere further down t...

2011/7/27
Abstract: It is given a simple proof of the collapse conjecture for a diagonal Bianchi type-IX vacuum space-time. It is shown that the codimension of the infinity stable attractor, restricted to the a...

Modified general relativity as a model for quantum gravitational collapse
Modified general relativity model quantum gravitational collapse
2010/12/20
We study a class of Hamiltonian deformations of the massless Einstein-Klein-Gordon system in spherical symmetry for which the Dirac constraint algebra closes. The system may be regarded as providing e...
Competition between symmetry breaking and onset of collapse in weakly coupled atomic condensates
symmetry breaking atomic condensates
2010/4/6
We analyze the symmetry breaking of matter-wave solitons in a pair of cigar-shaped traps coupled by tunneling of atoms. The model is based on a system of linearly coupled nonpolynomial Schr\"odinger e...
Collapse and revival in inter-band oscillations of a two-band Bose-Hubbard model
inter-band oscillations two-band Bose-Hubbard model
2010/3/10
We study the effect of a many-body interaction on inter-band oscillations in a two-band Bose-Hubbard model with external Stark force. Weak and strong inter-band oscillations are observed, where the la...
Collapse and stable self-trapping for Bose-Einstein condensates with 1/r^b type attractive interatomic interaction potential
Bose-Einstein condensates particles interatomic interaction potential
2010/4/2
We consider dynamics of Bose-Einstein condensates with long-range attractive interaction proportional to $1/r^b$ and arbitrary angular dependence. It is shown exactly that collapse of Bose-Einstein co...

Quantum Mechanical Effects Gravitational Collapse
2010/3/17
In this thesis we investigate quantum mechanical effects to various aspects of gravitational collapse. These quantum mechanical effects are implemented in the context of the Functional Schr\"odinger f...
Application of Abel-Plana formula for collapse and revival of Rabi oscillations in Jaynes-Cummings model
Application of Abel-Plana formula collapse and revival Rabi oscillations JaynesCummings model
2010/4/9
In this paper, we give an analytical treatment to study the behaviour of the collapse and the revival of the Rabi oscillations in the Jaynes-Cummings model (JCM). The JCM is an exactly soluble quantum...

Non-Markovian dynamics quantum particle subject general solution and main properties
2010/4/8
We analyze the non-Markovian dynamics of a quantum system subject to spontaneous collapse in space. After having proved, under suitable conditions, the separation of the center-of-mass and relative mo...
