Topological magnons, quantized spin waves featuring nontrivial boundary modes, present a promising route toward lossless information processing. Realizing practical devices typical…
Interaction-driven charge textures and unconventional superconductivity in strained monolayer graphene
Elias Andrade, Alejandro Jimeno-Pozo, Pierre A. Pantaleon +2
Two-dimensional systems with flat bands support correlated phases such as superconductivity. While twisted moiré systems, like twisted bilayer graphene, have revealed such states,…
Winding Berry dipole on uniaxially strained graphene/hBN/hBN moiré trilayers
Angiolo Huaman, Salvador Barraza-Lopez
Nonlinear Hall-like currents can be generated by a time-periodic alternating bias on two-dimensional (2D) materials lacking inversion symmetry. To hint that the moiré between graph…
Charging capacitors from thermal fluctuations using diodes
P. M. Thibado, J. C. Neu, Pradeep Kumar +2
We theoretically consider a graphene ripple as a Brownian particle coupled to an energy storage circuit. When circuit and particle are at the same temperature, the second law forbi…
Creating a three dimensional intrinsic electric dipole on rotated CrI bilayers
Shiva P. Poudel, Juan M. Marmolejo-Tejada, Joseph E. Roll +2
Two-dimensional (2D) materials are being explored as a novel multiferroic platform. One of the most studied magnetoelectric multiferroic 2D materials are antiferromagnetically-coup…
Dynamical control of topology in ferroelectric skyrmions via twisted light
Lingyuan Gao, Sergei Prokhorenko, Yousra Nahas +1
Twisted light carries a non-zero orbital angular momentum, that can be transferred from light to electrons and particles ranging from nanometers to micrometers. Up to now, the inte…
Two-atom-thin topological crystalline insulators lacking out of plane inversion symmetry
Salvador Barraza-Lopez, Gerardo G. Naumis
A two-dimensional topological crystalline insulator (TCI) with a single unit cell (u.c.) thickness is demonstrated here. To that end, one first shows that tetragonal ( in-plan…
Spin dependent analysis of homogeneous and inhomogeneous exciton decoherence in magnetic fields
V. Laurindo, E. D. Guarin Castro, G. M. Jacobsen +9
This paper discusses the combined effects of optical excitation power, interface roughness, lattice temperature, and applied magnetic fields on the spin-coherence of excitonic stat…
Planar Hall effect with sixfold oscillations in a Dirac antiperovskite
D. Huang, H. Nakamura, H. Takagi
The planar Hall effect (PHE), wherein a rotating magnetic field in the plane of a sample induces oscillating transverse voltage, has recently garnered attention in a wide range of…
Beyond Graphene: Low-Symmetry and Anisotropic 2D Materials
Salvador Barraza-Lopez, Fengnian Xia, Wenjuan Zhu +1
Low-symmetry 2D materials---such as ReS and ReSe monolayers, black phosphorus monolayers, group-IV monochalcogenide monolayers, borophene, among others---have more complex…
