Quantum stress in chaotic billiards
K. -F. Berggren, D. N. Maksimov, A. F. Sadreev +3
This article reports on a joint theoretical and experimental study of the Pauli quantum-mechanical stress tensor for open two-dimensional chaotic billiards. In the ca…
Low Energy Quantum System Simulation
Peter Cho, Karl Berggren
A numerical method for solving Schrodinger's equation based upon a Baker-Campbell-Hausdorff (BCH) expansion of the time evolution operator is presented herein. The technique manife…
Effects of accidental microconstriction on the quantized conductance in long wires
A. A. Starikov, I. I. Yakimenko, K. -F. Berggren +4
We have investigated the conductance of long quantum wires formed in GaAs/AlGaAs heterostructures. Using realistic fluctuation potentials from donor layers we have simulated numeri…
Current Statistics for Quantum Transport through Two-Dimensional Open Chaotic Billiards
Alexander I. Saichev, Hiromu Ishio, Almas F. Sadreev +1
The probability current statistics of two-dimensional open chaotic ballistic billiards is studied both analytically and numerically. Assuming that the real and imaginary parts of t…
Distribution of nearest distances between nodal points for the Berry function in two dimensions
Alexander I. Saichev, Karl-Fredrik Berggren, Almas F. Sadreev
According to Berry a wave-chaotic state may be viewed as a superposition of monochromatic plane waves with random phases and amplitudes. Here we consider the distribution of nodal…
Signatures of quantum chaos in nodal points and streamlines in electron transport through billiards
Karl-Fredrik Berggren, Konstantin N. Pichugin, Almas F. Sadreev +1
Streamlines and distributions of nodal points are used as signatures of chaos in coherent electron transport through three types of billiards, Sinai, Bunimovich and rectangular. Nu…
