Coherent backscattering in the topological Hall effect
Hong Liu, Rhonald Burgos Atencia, Nikhil Medhekar +1
The mutual interplay between electron transport and magnetism has attracted considerable attention in recent years, primarily motivated by strategies to manipulate magnetic degrees…
Quantum Kinetic Theory of Nonlinear Optical Currents: Finite Fermi surface and Fermi sea contributions
Pankaj Bhalla, Kamal Das, Amit Agarwal +1
The quantum kinetic framework provides a versatile method for investigating the dynamical optical and transport currents of crystalline solids. In this paper, starting from the den…
Chirality inversion and radius blow-up of a Néel-type skyrmion by a Pearl vortex
S. S. Apostoloff, E. S. Andriyakhina, P. A. Vorobyev +2
We develop a theory for the coaxial configuration of a Néel-type skyrmion and a Pearl vortex in thin superconductor-chiral ferromagnetic heterostructures. Using direct numerical so…
Reversible Transformation between Isolated Skyrmions and Bimerons
Kentaro Ohara, Xichao Zhang, Yinling Chen +9
Skyrmions and bimerons are versatile topological spin textures that can be used as information bits for both classical and quantum computing. The transformation between isolated sk…
Nonlinear chiral photocurrent in parity-violating magnetic Weyl semimetals
Shiva Heidari, Reza Asgari
The strong correlation between the non-trivial band topology and the magnetic texture makes magnetic Weyl semimetals excellent candidates for the manipulation and detection of magn…
3-Dimensional Tuning of an Atomically Defined Silicon Tunnel Junction
Matthew B. Donnelly, Joris G. Keizer, Yousun Chung +1
A requirement for quantum information processors is the in-situ tunability of the tunnel rates and the exchange interaction energy within the device. The large energy level separat…
