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...
On a proof of the collapse conjecture for a diagonal Bianchi type-IX vacuum space-time
collapse conjecture diagonal Bianchi type-IX vacuum space-time General Relativity and Quantum Cosmology
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...
Quantum Mechanical Effects in Gravitational Collapse
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 for a free quantum particle subject to spontaneous collapse in space: general solution and main properties
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...

Collapse of Interstellar Molecular Clouds
Magnetohydrodynamics interstellar clouds self--gravity Lorentz force Coriolis force
2010/4/13
In this paper we systematically investigate the length and time scales of an interstellar molecular cloud for collapse under the influence of self--gravity, magnetic field and Coriolis forces. We used...
