Optomechanics of Levitated Dielectric Particles
Optomechanics optical trapping Brownian motion macroscopic quantum mechanics sensor
2016/1/23
We review recent works on optomechanics of optically trapped microspheres and nanoparticles in vacuum, which provide an ideal system for studying macroscopic quan-tum mechanics and ultrasensitive forc...
Experimental Observation of Entanglement Duality for Identical Particles
entanglement duality quantum indistinguishability quantum mechanics
2016/1/22
It was shown recently that entanglement of identical particles has a feature called dualism (Bose and Home 2013 Phys. Rev. Lett. 110 140404), which is funda-mentally connected with quantum indistingui...

Abstract: We revisit considerations of temporal order in relativistic effects, taking into account Heisenberg's Uncertainty Principle. We then use a formulation of relativistic Quantum Mechanical equa...
Nonperturbative Analysis of a Quantum Mechanical Model for Unstable Particles
Nonperturbative Analysis Quantum Mechanical Model Unstable Particles
2010/11/9
We present a detailed non-perturbative analysis of the time-evolution of a well-known quantum-mechanical system - a particle between potential walls - describing the decay of unstable states. For suff...
Dynamical enhancement of spatial entanglement in massive particles
Dynamical enhancement spatial entanglement massive particles
2010/10/20
We discuss dynamical enhancement of entanglement in a driven Bose-Hubbard model and find
an enhancement of two orders of magnitude which is robust against fluctuations in experimental
parameters.
Confinement limit of Dirac particles in scalar 1D potentials
Confinement limit Dirac particles scalar 1D potentials
2010/4/9
We present a general proof that Dirac particles cannot be localized below their Compton length by symmetric but otherwise arbitrary scalar potentials. This proof does not invoke the Heisenberg uncerta...
Manipulation of quantum particles in rapidly oscillating potentials by inducing phase hops
quantum particles rapidly oscillating potentials phase hops
2010/4/13
Analytical calculations show that the mean-motion of a quantum particle trapped by a rapidly oscillating potential can be significantly manipulated by inducing phase hops, i.e., by instantaneously cha...
