Anomalous Conductances in an Ultracold Quantum Wire

Physical Review Letters, 2016
We analyze the recently measured anomalous transport properties of an ultracold gas through a ballistic constriction [S. Krinner et al., PNAS 201601812 (2016)]. The quantized conductance observed at weak interactions increases several-fold as the gas is made strongly interacting, which cannot be explained by the Landauer theory of single-channel ...

Atomic scale switches based on solid state ionics

Advances in Physics: X, 2022
The atomic scale switch, which operates on the principle of solid-state ionics, is an ultrafine device that takes advantage of the fact that the properties of materials can be changed significantly by the transport and chemical reaction of a small number

Beyond Wave-Nature Signatures: h-Independent Transport in Strongly-Scattering Quasi-2D Quantum Channels

Condensed Matter
The Landauer-Büttiker formalism provides a fundamental framework for mesoscopic transport, typically expressing conductance in units of the quantum of conductance, e2/h.

Quantum Tunneling-Induced Membrane Depolarization Can Explain the Cellular Effects Mediated by Lithium: Mathematical Modeling and Hypothesis

Membranes, 2021
Lithium imposes several cellular effects allegedly through multiple physiological mechanisms. Membrane depolarization is a potential unifying concept of these mechanisms. Multiple inherent imperfections of classical electrophysiology limit its ability to

Symmetry-related transport on a fractional quantum Hall edge

Physical Review Research, 2021
Low-energy transport in quantum Hall states is carried through edge modes and is dictated by bulk topological invariants and possibly microscopic Boltzmann kinetics at the edge.

The role of oxygen vacancies in the high cycling endurance and quantum conductance in BiVO4‐based resistive switching memory

InfoMat, 2020
Resistive random access memory (RRAM) has emerged as a new discipline promoting the development of new materials and devices toward a broad range of electronic and energy applications. Here, we realized a memristive device with weak dependence on the top

Casimir-cavity-induced conductance changes

Physical Review Research, 2021
The differential conductance of metal-insulator-metal devices increases when they are joined with Casimir cavities. An imbalance in injection of hot charge carriers from each side of the insulator is increased with thinner cavities that suppress more ...

Mixed‐class J‐domain protein scaffolds promote expanded aggregate handling and multivalent Hsp70 engagement during functional disaggregase assembly

FEBS Letters, EarlyView.
Protein aggregates threaten proteostasis and cell health. In human cells, Hsp70–J‐domain protein‐based disaggregases remove aggregates, but how they assemble remains unclear. Our biochemical findings show that DNAJA2‐ and DNAJB1‐containing disaggregase scaffolds enhance luciferase aggregate targeting, and that Hsp70 recruitment by both J‐domain ...

Multiple-path Quantum Interference Effects in a Double-Aharonov-Bohm Interferometer

Nanoscale Research Letters, 2010
We investigate quantum interference effects in a double-Aharonov-Bohm (AB) interferometer consisting of five quantum dots sandwiched between two metallic electrodes in the case of symmetric dot-electrode couplings by the use of the Green’s function

Reconstructing enzyme evolution by protein engineering

FEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...
