A Bloch decomposition based split-step pseudo spectral method for quantum dynamics with periodic potentials
Schrodinger equation Bloch decomposition time-splitting spectral method semiclassical asymptotics lattice potential
2012/5/24
We present a new numerical method for accurate computations of solutions to (linear) one dimensional Schr\"odinger equations with periodic potentials. This is a prominent model in solid state physics ...
Open system quantum dynamics with correlated initial states, not completely positive maps and non-Markovianity
quantum dynamics non-Markovianity Quantum Physics
2010/11/8
Dynamical A and B maps have been employed extensively by Sudarshan and co-workers to investigate open system evolution of quantum systems. A canonical structure of the A-map is introduced here. It is ...
Bianchi I model in terms of nonstandard loop quantum cosmology: Quantum dynamics
Bianchi I model terms nonstandard loop quantum cosmology Quantum dynamics
2010/11/9
We analyze the quantum Bianchi I model in the setting of the nonstandard loop quantum cosmology. Elementary observables are used to quantize the volume operator. The spectrum of the volume operator i...

We investigate the dynamics of pairs of Fermions and Bosons released from a box and find that their populations have unique generic properties ensuing from the axioms of quantum statistics and symmetr...
Non-relativistic Gravity in Entropic Quantum Dynamics
Non-relativistic Gravity Entropic Quantum Dynamics
2010/10/29
Symmetries and transformations are explored in the framework of entropic quantum dynamics. Two conditions arise that are required for any transformation to qualify as a symmetry. The heart of this wor...
Stochastic quantum dynamics in 1D and lattice systems
Stochastic quantum dynamics 1D lattice systems
2010/10/21
We show that stochastic phase-space methods within the truncated Wigner approximation can be used to solve non-equilibrium dynamics of bosonic atoms in 1d traps. We consider systems both with and with...
Quantum Dynamics of Radical-Ion-Pair Reactions
Quantum Dynamics Radical-Ion-Pair Reactions
2010/10/20
Radical-ion-pair reactions were recently shown to represent a rich biophysical laboratory for the application of quantum measurement theory methods and concepts, casting doubt on the validity of the t...
In this work we investigate the quantum dynamics of three di erent con gurations of nonlinear cavity systems. We begin by carrying out a quantum analysis of a dc superconducting quantum interference d...
Quantum dynamics of instability-induced pulsations of a Bose-Einstein condensate in an optical lattice
Quantum dynamics instability-induced pulsations Bose-Einstein condensate optical lattice
2010/4/13
We study the dynamics of a Bose-Einstein condensate in a one-dimensional optical lattice in the limit of weak atom-atom interactions, including an approximate model for quantum fluctuations. A pulsati...
