Tunable Quantum Tunneling through a Graphene/Bi2Se3 Heterointerface for the Hybrid Photodetection Mechanism. [PDF]
ACS Appl Mater Interfaces, 2021 Graphene-based van der Waals heterostructures are promising building blocks for broadband photodetection because of the gapless nature of graphene. However, their performance is mostly limited by the inevitable trade-off between low dark current and ...

On Quantum Speedups for Nonconvex Optimization via Quantum Tunneling Walks [PDF]
Quantum, 2022 Classical algorithms are often not effective for solving nonconvex optimization problems where local minima are separated by high barriers. In this paper, we explore possible quantum speedups for nonconvex optimization by leveraging the global effect of ...

Quantum tunneling in deep potential wells and strong magnetic field revisited [PDF]
Pure and Applied Analysis, 2022 Inspired by a recent paper$^*$ by C. Fefferman, J. Shapiro and M. Weinstein, we investigate quantum tunneling for a Hamiltonian with a symmetric double well and a uniform magnetic field.

Skyrmion helicity: Quantization and quantum tunneling effects [PDF]
Physical review B, 2022 We derive the quantization of magnetic helicity in the solid-state and demonstrate tunable macroscopic quantum tunneling, coherence, and oscillation for a skyrmion spin texture stabilized in frustrated magnets. We also discuss the parameter space for the
