Optical absorption and carrier multiplication at graphene edges in a magnetic field
Friedemann Queisser, Sascha Lang, Ralf Schützhold
We study optical absorption at graphene edges in a transversal magnetic field. The magnetic field bends the trajectories of particle- and hole excitations into antipodal direction…
Dynamically assisted tunneling in the impulse regime
Christian Kohlfürst, Friedemann Queisser, Ralf Schützhold
We study the enhancement of tunneling through a potential barrier by a time-dependent electric field with special emphasis on pulse-shaped vector potentials such as $A_x(t)=…
Comment on "Enhanced deuterium-tritium fusion cross sections in the presence of strong electromagnetic fields"
Friedemann Queisser, Ralf Schützhold
In their article [Phys.\ Rev.\ C {\bf 100}, 064610 (2019)], Lv, Duan, and Liu study the enhancement of deuterium-tritium fusion reactions by the electromagnetic field of an x-ray f…
Boltzmann relaxation dynamics of strongly interacting spinless fermions on a lattice
Friedemann Queisser, Sebastian Schreiber, Peter Kratzer +1
Motivated by the recent interest in non-equilibrium phenomena in quantum many-body systems, we study strongly interacting fermions on a lattice by deriving and numerically solving…
Doublon bottleneck in the ultrafast relaxation dynamics of hot electrons in 1T-TaS_2
Isabella Avigo, Friedemann Queisser, Ping Zhou +4
Employing time-resolved photoelectron spectroscopy we analyze the relaxation dynamics of hot electrons in the charge density wave / Mott material 1T-TaS_2. At 1.2 eV above the Ferm…
Dynamically assisted nuclear fusion
Friedemann Queisser, Ralf Schützhold
We consider the prototypical deuterium-tritium fusion reaction. At intermediate initial kinetic energies (in the keV regime), a major bottle-neck of this reaction is the Coulomb ba…
