Quench dynamics of a confined ultracold Fermi gas: Direct visibility of the Goldstone mode in the single-particle excitations
P. Kettmann, S. Hannibal, M. D. Croitoru +2
We present a numerical study of a confined ultracold Fermi gas showing that the Goldstone mode of the BCS gap is directly visible in the dynamics of the single-particle excitations…
Relaxation and coherent oscillations in the spin dynamics of II-VI diluted magnetic quantum wells
Florian Ungar, Moritz Cygorek, Pablo I. Tamborenea +1
We study theoretically the ultrafast spin dynamics of II-VI diluted magnetic quantum wells in the presence of spin-orbit interaction. We extend a recent study where it was shown th…
Non-Markovian Effects in the Spin Transfer Dynamics in Diluted Magnetic Semiconductors due to Excitation in Proximity to the Band Edge
Moritz Cygorek, Vollrath Martin Axt
The non-Markovian effects in the spin dynamics in diluted magnetic semiconductors found in quantum kinetic calculations can be reproduced very well by a much simpler effective sing…
Comparison between a quantum kinetic theory of spin transfer dynamics in Mn doped bulk semiconductors and its Markov limit for non-zero Mn magnetization
Moritz Cygorek, Vollrath Martin Axt
We investigate the transfer between carrier and Mn spins due to the s-d-exchange interaction in a Mn doped bulk semiconductor within a microscopic quantum kinetic theory. We demons…
Non-perturbative Correlation Effects in Diluted Magnetic Semiconductors
Moritz Cygorek, Pablo Ignacio Tamborenea, Vollrath Martin Axt
The effects of carrier-impurity correlations due to a Kondo-like spin-spin interaction in diluted magnetic semiconductors are investigated. These correlations are not only responsi…
Ultrafast spin dynamics in II-VI diluted magnetic semiconductors with spin-orbit interaction
Florian Ungar, Moritz Cygorek, Pablo I. Tamborenea +1
We study theoretically the ultrafast spin dynamics of II-VI diluted magnetic semiconductors in the presence of spin-orbit interaction. Our goal is to explore the interplay or compe…
