The one-dimensional stratum in the boundary of the moduli stack of stable curves
Joerg Zintl
The moduli stack of Deligne-Mumford stable curves of genus g admits a stratification, so that the number of nodes of the curves belonging to one stratum is constant. The irreducibl…
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…
Time-resolved Observation and Control of Superexchange Interactions with Ultracold Atoms in Optical Lattices
S. Trotzky, P. Cheinet, S. Fölling +7
Quantum mechanical superexchange interactions form the basis of quantum magnetism in strongly correlated electronic media. We report on the direct measurement of superexchange inte…
Population trapping in three-state quantum loops revealed by Householder reflections
A. A. Rangelov, N. V. Vitanov, B. W. Shore
Population trapping occurs when a particular quantum-state superposition is immune to action by a specific interaction, such as the well-known dark state in a three-state lambda sy…
Dark-State Polaritons for multi-component and stationary light fields
F. E. Zimmer, J. Otterbach, R. G. Unanyan +2
We present a general scheme to determine the loss-free adiabatic eigensolutions (dark-state polaritons) of the interaction of multiple probe laser beams with a coherently driven at…
Realization of XNOR and NAND spin-wave logic gates
T. Schneider, A. A. Serga, B. Leven +3
We demonstrate the functionality of spin-wave logic XNOR and NAND gates based on a Mach-Zehnder type interferometer which has arms implemented as sections of ferrite film spin-wave…
