Resonant spin amplification in Faraday geometry
P. Schering, E. Evers, V. Nedelea +6
We demonstrate the realization of the resonant spin amplification (RSA) effect in Faraday geometry where a magnetic field is applied parallel to the optically induced spin polariza…
Quantum Coherence from Periodic Driving with Laser Pulses and Decay
Goetz S. Uhrig
Non-equilibrium physics is a particularly fascinating field of current research. Generically, driven systems are gradually heated up so that quantum effects die out. In contrast, w…
Spin-wave velocities, density of magnetic excitations, and NMR relaxation in ferro-pnictides
Andrew Ong, Goetz S. Uhrig, Oleg P. Sushkov
We perform an analysis of the experimentally known temperature dependence of the staggered magnetization in the antiferromagnetic phase. This analysis allows us to put an upper lim…
Pnictides as frustrated quantum antiferromagnet close to a quantum phase transition
Goetz S. Uhrig, Michael Holt, Jaan Oitmaa +2
We present a detailed description of the dynamics of the magnetic modes in the recently discovered superconducting pnictides using reliable self-consistent spin-wave theory and ser…
Spectral Properties of Magnetic Excitations in Cuprate Two-Leg Ladder Systems
Kai P. Schmidt, Goetz S. Uhrig
This article summarizes and extends the recent developments in the microscopic modeling of the magnetic excitations in cuprate two-leg ladder systems. The microscopic Hamiltonian c…
The Structure of Operators in Effective Particle-Conserving Models
Christian Knetter, Kai P. Schmidt, Goetz S. Uhrig
For many-particle systems defined on lattices we investigate the global structure of effective Hamiltonians and observables obtained by means of a suitable basis transformation. We…
