Quantum Scars and Caustics in Majorana Billiards

Kavli Affiliate: Michael Wimmer | First 5 Authors: R. Johanna Zijderveld, A. Mert Bozkurt, Michael Wimmer, İnanç Adagideli, | Summary: We demonstrate that the classical dynamics influence the localization behaviour of Majorana wavefunctions in Majorana billiards. By using a connection between Majorana wavefunctions and eigenfunctions of a normal state Hamiltonian, we show that Majorana wavefunctions […]
