Critical superconductors
A. Vagov, A. A. Shanenko, M. V. Milošević +3
Bogomolnyi critical point, originally introduced in string theories, is fundamental to superconductivity. At the critical temperature T_c it marks the sharp border between ideally…
Energy transport and coherence properties of acoustic phonons generated by optical excitation of a quantum dot
D. Wigger, S. Lüker, D. E. Reiter +3
The energy transport of acoustic phonons generated by the optical excitation of a quantum dot as well as the coherence properties of these phonons are studied theoretically both fo…
Competition between loss channels in quantum-dot cavity systems: unconventional consequences
A. Vagov, M. Glässl, M. D. Croitoru +2
We demonstrate that in quantum-dot cavity systems, the interplay between acoustic phonons and photon losses introduces novel features and characteristic dependencies in the system…
Ginzburg-Landau theory for multiband superconductors: microscopic derivation
N. V. Orlova, A. A. Shanenko, M. V. Milošević +3
A procedure to derive the Ginzburg-Landau (GL) theory from the multiband BCS Hamiltonian is developed in a general case with an arbitrary number of bands and arbitrary interaction…
Non-Markovian spin transfer dynamics in magnetic semiconductors despite short memory times
Christoph Thurn, Moritz Cygorek, Vollrath Martin Axt +1
A quantum kinetic theory of the spin transfer between carriers and Mn atoms in a Mn doped diluted magnetic semiconductor is presented. It turns out that the typical memory time ass…
Proposed robust and high-fidelity preparation of excitons and biexcitons in semiconductor quantum dots making active use of phonons
M. Glässl, A. M. Barth, V. M. Axt
It is demonstrated how the exciton and the biexciton state of a quantum dot can be prepared with high fidelity on a picosecond time-scale by driving the dot with a strong laser pul…
