A robust and tunable halogen bond organocatalyzed 2-deoxyglycosylation involving quantum tunneling
Nature Communications, 2020 The development of noncovalent halogen bonding (XB) catalysis is rapidly gaining traction, as isolated reports documented better performance than the well-established hydrogen bonding thiourea catalysis.

Molecular motor crossing the frontier of classical to quantum tunneling motion
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Conversion of undirected energy input into directed motion on molecular scales is the basis for controlled movements in living organisms. In this context, fundamental insights can be obtained by investigating artificial molecular machines ...

Quantum Gravitational Non-Singular Tunneling Wavefunction Proposal
Physical Sciences Forum, 2023 It has recently been shown that the tunneling wavefunction proposal is consistent with loop quantum geometry corrections, including both holonomy and inverse scale factor corrections, in the gravitational part of a spatially closed isotropic model with a

Quantum interference effects in multi-channel correlated tunneling structures
Scientific Reports, 2021 In multi-channel tunneling systems quantum interference effects modify tunneling conductance spectra due to Fano effect. We investigated the impact of Hubbard type Coulomb interaction on tunneling conductance spectra for the system formed by several ...

Evidence for the Josephson Effect in Quantum Hall Bilayers [PDF]
, 2004 This thesis presents tunneling measurements on bilayer two-dimensional (2D) electrons systems in GaAs/AlGaAs double quantum wells. 2D-2D tunneling is applied here as a probe of the inter-layer correlated quantum Hall state at total Landau level filling

Thermally activated charge fluctuations in GaAs double quantum dots [PDF]
, 2014 In this thesis, laterally defined GaAs quantum dots and double quantum dots are investigated by means of real-time charge sensing. A quantum dot charge sensor, adjacent to the investigated double dot system, detects single electron tunneling with ...

Effects of neglecting carrier tunneling on electrostatic potential in calculating direct tunneling gate current in deep submicron MOSFETs [PDF]
, 2002 We investigate the validity of the assumption of neglecting carrier tunneling effects on self-consistent electrostatic potential in calculating direct tunneling gate current in deep submicron MOSFETs. Comparison between simulated and experimental results

A diode device combining lateral field-effect transport and vertical tunneling in a multi-quantum-well heterostructure [PDF]
, 1992 The authors discuss an electronic device with asymmetric contacts to a InGaAs-InP multilayer heterostructure. Current enters via an alloyed ohmic contact into the quantum wells (QWs) and flows laterally along capacitively coupled channels.
