Robust nonequilibrium surface currents in the three-dimensional Hofstadter model [PDF]
Physical Review Research, 2022 Genuinely two-dimensional robust crosscurrents—which flow against the natural direction of heat flux— have been missing since the discovery of their one-dimensional counterpart. We provide a setup to realize them on a cubic three-dimensional (3D) lattice

Engineering stable quantum currents at bulk boundaries [PDF]
, 2019 We study transport properties of discrete quantum dynamical systems on the lattice, in particular Coined Quantum Walks and the Chalker--Coddington model. We prove existence of a non trivial charge transport and that the absolutely continuous spectrum covers the whole unit circle under mild assumptions.

Marginally stable current sheets in collisionless magnetic reconnection
Physical Review E, 2022 Non-collisional current sheets that form during the nonlinear development of magnetic reconnection are characterized by a small thickness, of the order of the electron skin depth. They can become unstable to the formation of plasmoids, which allows the magnetic reconnection process to reach high reconnection rates.

Quasiprobability currents on the sphere [PDF]
, 2020 We present analytic expressions for the s-parametrized currents on the sphere for both unitary and dissipative evolutions. We examine the spatial distribution of the flow generated by these currents for quadratic Hamiltonians. The results are applied for

Gd3+ and calcium sensitive, sodium leak currents are features of weak membrane-glass seals in patch clamp recordings. [PDF]
PLoS ONE, 2014 The properties of leaky patch currents in whole cell recording of HEK-293T cells were examined as a means to separate these control currents from expressed sodium and calcium leak channel currents from snail NALCN leak channels possessing both sodium ...

Traceable low-current measurements for a novel ionization gauge suitable as reference standard
Measurement: Sensors, 2021 A novel ionization gauge was developed where the electron beam is guided through the ionization space in a straight path. This design was chosen in order to develop a more stable ionization vacuum gauge suitable as reference standard in the range of 10−6

Using Matlab/Simulink Software Package to Investigate Fault Behaviors in HVDC System
Mathematics, 2022 Existing studies show that several performance issues will arise in the HVDC link during the three phase-to-ground fault at the side of the inverter and that the DC voltage will oscillate around zero and will not affect the rectifier of the AC system ...

Field-aligned currents and ionospheric parameters deduced from EISCAT radar measurements in the post-midnight sector [PDF]
, 2002 International audienceAttempting to derive the field-aligned current (FAC) density using the EISCAT radar and to understand the role of the ionosphere on closing FACs, we conducted special radar experiments with the EISCAT radar on 9 October 1999.
