Effects of short-range interactions on transport through quantum point contacts: A numerical approach
Andreas Lassl, Peter Schlagheck, Klaus Richter
We study electronic transport through a quantum point contact, where the interaction between the electrons is approximated by a contact potential. Our numerical approach is based o…
Influence of classical resonances on chaotic tunnelling
Amaury Mouchet, Christopher Eltschka, Peter Schlagheck
Dynamical tunnelling between symmetry-related stable modes is studied in the periodically driven pendulum. We present strong evidence that the tunnelling process is governed by non…
Resonance-assisted decay of nondispersive wave packets
Sandro Wimberger, Peter Schlagheck, Christopher Eltschka +1
We present a quantitative semiclassical theory for the decay of nondispersive electronic wave packets in driven, ionizing Rydberg systems. Statistically robust quantities are extra…
