Lead-Orientation-Dependent Wave Function Scarring in Open Quantum Dots

Abstract: Experimental studies of the conductance of open quantum dots show a series of highly regular oscillations at low temperatures as the voltage applied to their defining gates is varied. Simulations of quantum transport through these dots reveal the oscillations to be correlated to the recurrence of specific groups of wave function scars. We furthermore find that nominally identical dots, differing only in the orientation of their input and output contacts, may be used to excite different families of scars, givin… Show more

“…In semiconductor physics, chaotic electron transport has been explored using a variety of two-dimensional billiard and antidot barrier structures [1][2][3][4][5][6][7][8][9][10][11][12], in superlattices (SLs) [13][14][15], and in resonant tunnelling diodes containing a wide quantum well with a tilted magnetic field [1,[16][17][18]. Despite the diversity of these experiments, they all involve systems in which the transition to chaos occurs by the gradual and progressive destruction of stable orbits in response to an increasing perturbation.…”

“…For example, in optical resonators [8] the power emitted at a certain point of the boundary depends strongly on the angle of incidence of the wave (total internal reflection). Also in quantum dots effects of eigenfunction directionality have been measured using tilted leads [12].In this paper we analyze for the first time dynamical correlations between points in phase space. Our results are surprising in view of the fact that spatial two-point correlators of eigenfunction amplitudes or densities vanish in the semiclassical limith → 0 for any x = x ′ [14].…”
