Mean-field dynamics of a non-Hermitian Bose-Hubbard dimer
E. M. Graefe, H. J. Korsch, A. E. Niederle
We investigate an -particle Bose-Hubbard dimer with an additional effective decay term in one of the sites. A mean-field approximation for this non-Hermitian many-particle syste…
Barrier transmission for the Nonlinear Schrödinger Equation: Surprises of nonlinear transport
K. Rapedius, H. J. Korsch
In this communication we report on a peculiar property of barrier transmission that systems governed by the nonlinear Schroedinger equation share with the linear one: For unit tran…
Coherent pulsed excitation of degenerate multistate systems: Exact analytic solutions
E. S. Kyoseva, N. V. Vitanov
We show that the solution of a multistate system composed of N degenerate lower (ground) states and one upper (excited) state can be reduced by using the Morris-Shore transformatio…
Physical realization of coupled Hilbert-space mirrors for quantum-state engineering
E. S. Kyoseva, N. V. Vitanov, B. W. Shore
Manipulation of superpositions of discrete quantum states has a mathematical counterpart in the motion of a unit-length statevector in an N-dimensional Hilbert space. Any such stat…
Quantum information processing with single photons and atomic ensembles in microwave coplanar waveguide resonators
David Petrosyan, Michael Fleischhauer
We show that pairs of atoms optically excited to the Rydberg states can strongly interact with each other via effective long-range dipole-dipole or van der Waals interactions media…
Continuous variable versus EIT-based quantum memories
Z. Kurucz, M. Fleischhauer
We discuss a general model of a quantum memory for a single light mode in a collective mode of atomic oscillators. The model includes interaction Hamiltonians that are of second or…
