Random matrix approach to `nonuniversal' conductance
Petr Seba, Karol Zyczkowski, Jakub Zakrzewski
Recent experiments on the conductance of high quality quantum wires have revealed an unexpected feature: the quantization step of the conductance is apparently system dependent. We…
Probability current tornado loops in three-dimensional scattering
Pavel Exner, Petr Seba
We consider scattering of a three-dimensional particle on a finite family of delta potentials. For some parameter values the scattering wavenctions exhibit nodal lines in the form…
Topologically induced vortex magnetance of a quantum device
P. Exner, P. Seba, A. F. Sadreev +2
We consider resonant vortices around nodal points of the wavefunction in electron transport through a mesoscopic device. With a suitable choice of the device geometry, the dominati…
Distribution of the wave function inside chaotic partially open systems
P. Seba, F. Haake, M. Kus +3
We demonstrate both theoretically and experimentally that the distribution of the wavefunction inside a partially open chaotic timereversal symmetric system displays significant de…
Resonance statistics in a microwave cavity with a thin antenna
P. Exner, P. Šeba
We propose a model for scattering in a flat resonator with a thin antenna. The results are applied to rectangular microwave cavities. We compute the resonance spacing distribution…
