Quantum Computational Method of Finding the Ground State Energy and Expectation Values
Sangchul Oh
We propose a new quantum computational way of obtaining a ground-state energy and expectation values of observables of interacting Hamiltonians. It is based on the combination of t…
Femtosecond Photodissociation of Molecules Facilitated by Noise
Kamal P. Singh, Anatole Kenfack, Jan M. Rost
We investigate the dynamics of diatomic molecules subjected to both a femtosecond mid-infrared laser pulse and Gaussian white noise. The stochastic Schrödinger equation with a Mors…
Coherent backscattering of light from saturated atoms
Vyacheslav Shatokhin, Thomas Wellens, Cord Müller +1
We survey recent progress achieved in understanding the impact of inelastic processes on coherent backscattering of light from cold atoms that are saturated by a powerful laser fie…
Nonlinear Effects in Pulse Propagation through Doppler-Broadened Closed-Loop Atomic Media
Robert Fleischhaker, Jörg Evers
Nonlinear effects in pulse propagation through a medium consisting of four-level double--type systems are studied theoretically. We apply three continous-wave driving fields and…
The design of Kinetic Functionals for Many-Body Electron Systems : Combining analytical theory with Monte Carlo sampling of electronic configurations
Luca M. Ghiringhelli, Luigi Delle Site
In a previous work [L.Delle Site, J.Phys.A 40, 2787 (2007)] the derivation of an analytic expression for the kinetic functional of a many-body electron system has been proposed. Th…
Anyonic statistics with continuous variables
Jing Zhang, Changde Xie, Kunchi Peng +1
We describe a continuous-variable scheme for simulating the Kitaev lattice model and for detecting statistics of abelian anyons. The corresponding quantum optical implementation is…
