On Quantum Speedups for Nonconvex Optimization via Quantum Tunneling Walks [PDF]
Quantum, 2023 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 ...

Macroscopic quantum tunneling: from quantum vortices to black holes and Universe [PDF]
Journal of Experimental and Theoretical Physics, 2022 The paper has been prepared for the JETP issue, dedicated to the 95th anniversary of the birth of E.I. Rashba. E. Rashba stood at the origins of macroscopic quantum tunneling together with his colleagues from the Landau Institute S.V.

Quantum tunneling of thermal protons through pristine graphene [PDF]
Journal of Chemical Physics, 2018 peer reviewedEngineering of atomically thin membranes for hydrogen isotope separation is an actual challenge which has a broad range of applications. Recent experiments [M. Lozada-Hidalgo et al., Science 351, 68 (2016)] unambiguously demonstrate an order-

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

ACS Applied Materials and 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 ...

Quantum Tunneling on Graphs [PDF]
Communications in Mathematical Physics, 2012 We explore the tunneling behavior of a quantum particle on a finite graph, in the presence of an asymptotically large potential. Surprisingly the behavior is governed by the local symmetry of the graph around the wells.

The Quantum Tunneling of Ions Model Can Explain the Pathophysiology of Tinnitus
Brain Sciences, 2022 Tinnitus is a well-known pathological entity in clinical practice. However, the pathophysiological mechanisms behind tinnitus seem to be elusive and cannot provide a comprehensive understanding of its pathogenesis and clinical manifestations.

Optical antennas driven by quantum tunneling: a key issues review [PDF]
Reports on progress in physics. Physical Society, 2019 Analogous to radio- and microwave antennas, optical nanoantennas are devices that receive and emit radiation at optical frequencies. Until recently, the realization of electrically driven optical antennas was an outstanding challenge in nanophotonics. In
