Concentration Behavior of Ground States for -Critical Schrödinger Equation with a Spatially Decaying Nonlinearity
Yong Luo, Shu Zhang
We consider the following time-independent nonlinear -critical Schrödinger equation \[ -Δu(x)+V(x)u(x)-a|x|^{-b}|u|^{1+\frac{4-2b}{N}}=μu(x)\,\ \hbox{in}\,\ \mathbb{R}^N, \] w…
On the anomalous low-resistance state and exceptional Hall component in hard-magnetic Weyl nanoflakes
Qingqi Zeng, Gangxu Gu, Gang Shi +7
Magnetic topological materials, which combine magnetism and topology, are expected to host emerging topological states and exotic quantum phenomena. In this study, with the aid of…
Biasing topological charge injection in topological matter
Mostafa Tanhayi Ahari, Shu Zhang, Ji Zou +1
We explore the interplay between topologies in the momentum and real spaces to formulate a thermodynamic description of nonequilibrium injection of topological charges under extern…
Energy storage in magnetic textures driven by vorticity flow
Dalton Jones, Ji Zou, Shu Zhang +1
An experimentally feasible energy-storage concept is formulated based on vorticity (hydro)dynamics within an easy-plane insulating magnet. The free energy, associated with the magn…
Antiferromagnet-Based Neuromorphics Using Dynamics of Topological Charges
Shu Zhang, Yaroslav Tserkovnyak
We propose a spintronics-based hardware implementation of neuromorphic computing, specifically, the spiking neural network, using topological winding textures in one-dimensional an…
Multiphase Magnetism in Yb2Ti2O7
A. Scheie, J. Kindervater, S. Zhang +7
We document the coexistence of ferro- and anti-ferromagnetism in pyrochlore using three neutron scattering techniques on stoichiometric crystals: elastic neutron…
