The origin of the phase in the interference of Bose-Einstein condensates
The condensation condensation wave function treatment the particles
2014/12/20
We consider the interference of two overlapping ideal Bose-Einstein condensates. The usual description of this phenomenon involves the introduction of a condensate wave function with a definite phase....
Evolution of additional (hidden) quantum variables in the interference of Bose-Einstein condensates
Additional variable hidden variables quantum mechanics the high concentration condensate
2014/12/20
Additional variables (also often called “hidden variables”) are sometimes added to standard quantum mechanics in order to remove its indeterminism or “incompleteness” and to make the measurement proce...
Interference of Bose-Einstein condensates: Quantum nonlocal effects
Quantum measurement quantum system condensate particle measurement and quantum mechanics
2014/12/19
Quantum systems in Fock states do not have a phase. When two or more Bose-Einstein condensates are sent into interferometers, they nevertheless acquire a relative phase under the effect of quantum mea...
Explanation of quantum interference: Classical trajectories plus ballistic diffusion caused by zero-point fluctuations
quantum mechanics, ballistic diusion, nonequilibrium thermodynamics, zero-point
2011/9/29
A purely classical explanation of quantum mechanical interference is given. We claim that for every single \particle" a thermal context can be dened, which re ects its embedding within boundary condi...
Experimental Evidence for a Dynamical Non-Locality Induced Effect in Quantum Interference Using Weak Values
Experimental Evidence Dynamical Non-Locality Induced Effect in Quantum Interference Weak Values
2010/11/5
The quantum theoretical concepts of modular momentum and dynamical non-locality, which were introduced four decades ago, have recently been used to explain single particle quantum interference phenome...

2010/11/11
Mechanical dissipation poses an ubiquitous challenge to the performance of nanomechanical devices. Here we analyze the support-induced dissipation of high-stress nanomechanical resonators. We develop ...
Observation of Young's Double-Slit Interference with the Three-Photon N00N State
Observation Young's Double-Slit Interference Three-Photon N00N State
2010/10/21
Spatial interference of quantum mechanical particles exhibits a fundamental feature of quantum
mechanics. A two-mode entangled state of N particles known as N00N state can give rise to nonclassical i...

2010/10/27
We theoretically analyze interference patterns of parametrically driven one dimensional ultracold atomic gases. By modulating the interaction strength periodically in time, we propose to excite collec...

Quantum mechanics two-slit experiment interference scattering theory
2010/10/19
Marcella has presented a straightforward technique employing the Dirac formalism to calculate single- and double-slit interference patterns. He claims that no reference is made to classical optics or ...

ports of a beam splitter when a single-photon Fock state and a coherent state are incident on
the input ports. The output states turn out to be a statistical mixture between a displaced Fock state an...

2010/4/13
We study the effects of interference on the quenching dynamics of a one-dimensional spin 1/2 $XY$ model in the presence of a transverse field ($h(t)$) which varies sinusoidally with time as $h = h_0\c...
