Detection of coherent magnons via ultrafast pump-probe reflectance spectroscopy in multiferroic Ba0.6Sr1.4Zn2Fe12O22

D. Talbayev, S. A. Trugman, A. V. Balatsky +3

We report the detection of a magnetic resonance mode in multiferroic Ba0.6Sr1.4Zn2Fe12O22 using time domain pump-probe reflectance spectroscopy. Magnetic sublattice precession is c…

Optimal non-linear passage through a quantum critical point

Roman Barankov, Anatoli Polkovnikov

We analyze the problem of optimal adiabatic passage through a quantum critical point. We show that to minimize the number of defects the tuning parameter should be changed as a pow…

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…

Linear response theory for a pair of coupled one-dimensional condensates of interacting atoms

Vladimir Gritsev, Anatoli Polkovnikov, Eugene Demler

We use quantum sine-Gordon model to describe the low energy dynamics of a pair of coupled one-dimensional condensates of interacting atoms. We show that the nontrivial excitation s…

Frustration of Decoherence in Open Quantum Systems

E. Novais, A. H. Castro Neto, L. Borda +2

We study a model of frustration of decoherence in an open quantum system. Contrary to other dissipative ohmic impurity models, such as the Kondo model or the dissipative two-level…
