Spectroscopy of Quantum Phase Slips: Visualizing Complex Real-Time Instantons
Foster Thompson, Daniel K. J. Boneß, Mark Dykman +1
Parametrically driven oscillators can emerge as a basis for the next generation of qubits. Classically, these systems exhibit two stable oscillatory states with opposite phases. Up…

Contact interactions and Kronig-Penney Models in Hermitian and PT-symmetric Quantum Mechanics
Foster Thompson, Katherine Jones-Smith, Harsh Mathur +1
The delta function potential is a simple model of zero-range contact interaction in one dimension. The Kronig-Penney model is a one-dimensional periodic array of delta functions th…
