Hace 3 días · [2405.14844] Electric, thermal, and thermoelectric magnetoconductivity for Weyl/multi-Weyl semimetals in planar Hall set-ups induced by the combined effects of topology and strain. Condensed Matter > Mesoscale and Nanoscale Physics. [Submitted on 23 May 2024]
Hace 4 días · Received: Accepted: Split-Screen. Views. PDF. Share. Tools. We investigate the quantum interference of the electron–hole conversions from the two interfaces in a Weyl semimetal (WSM)-based hybrid structure, in which a superconducting WSM is sandwiched in between two normal ones.
Hace 5 días · In this paper, we prove a stronger type of Heisenberg–Pauli–Weyl uncertainty principle for ambiguity function. An example is used to demonstrate the obtained result, and related uncertainty principles for short-time Fourier transform and Wigner distribution are given, respectively.
Hace 3 días · We find it causes spin-carrying altermagnetic Weyl points, and observe their protected Fermi-arc surface states. This establishes that in altermagnets the large energy scale intrinsic to the spin-splitting - orders of magnitude larger that the relativistic spin-orbit coupling - creates its own realm of robust electronic topology ...
Hace 4 días · Ed Hayward | University Communications | February 2023. Quantum sensors can be used to reveal a surprising new mechanism for converting light into electricity in Weyl semimetals, Boston College Assistant Professor of Physics Brian Zhou and colleagues report in the journal Nature Physics.
Hace 3 días · In this work we propose a novel device for controlling the flow of information using Weyl fermions. Based on a previous work by our group, we show that it is possible to fully control the flow of Weyl fermions on several different channels by applying an electric field perpendicular to the direction of motion of the particles on each ...
Hace 2 días · Neustadt/Weinstraße - Die russische Menschenrechtsaktivistin Irina Scherbakowa ist bei einem Festakt mit dem Hambacher Freiheitspreis 1832 geehrt worden. Die mit 10.000 Euro dotierte Auszeichnung wurde der Kulturwissenschaftlerin am Freitag im Beisein des früheren Bundespräsidenten Joachim Gauck im Hambacher Schloss überreicht.
