We present experiments on the tuning of the spin-orbit interaction in a two-dimensional electron gas in an asymmetric InAs/AlSb quantum well using a gate. The observed dependence of the spinâ€¦ (More)

The Wigner time delay is a measure of the time spent by a particle inside the scattering region of an open system. For chaotic systems, the statistics of the individual delay times (whose average isâ€¦ (More)

The time evolution of the strength of the Earthâ€™s virtual axial dipole moment (VADM) is analyzed by relating it to the Fokker-Planck equation, which describes a random walk with VADM-dependent driftâ€¦ (More)

For chaotic cavities with scattering leads attached, transport properties can be approximated in terms of the classical trajectories that enter and exit the system. With a semiclassical treatmentâ€¦ (More)

The Wigner time delay, defined by the energy derivative of the total scattering phase shift, is an important spectral measure of an open quantum system characterizing the duration of the scatteringâ€¦ (More)

The Ehrenfest-time scale in quantum transport separates essentially classical propagation from wave interference and here we consider its effect on the transmission and reflection through quantumâ€¦ (More)

Quantum cavities or dots have markedly different properties depending on whether their classical counterparts are chaotic or not. Connecting a superconductor to such a cavity leads to notableâ€¦ (More)
