Quantum Imaging of Magnetic Phase Transitions and Spin Fluctuations in Intrinsic Magnetic Topological Nanoflakes
Nathan J. McLaughlin, Chaowei Hu, Mengqi Huang +6
Topological materials featuring exotic band structures, unconventional current flow patterns, and emergent organizing principles offer attractive platforms for the development of n…
Intertwining of lasing and superradiance under spintronic pumping
Oksana Chelpanova, Alessio Lerose, Shu Zhang +3
We introduce a quantum optics platform featuring the minimal ingredients for the description of a spintronically pumped magnon condensate, which we use to promote driven-dissipativ…
A generalized model of magnon kinetics and subgap magnetic noise
Haocheng Fang, Shu Zhang, Yaroslav Tserkovnyak
Magnetic noise spectroscopy provides a noninvasive probe of spin dynamics in magnetic materials. We consider two-dimensional magnetically ordered insulators with magnon excitations…
Sleuthing out exotic quantum spin liquidity in the pyrochlore magnet CeZrO
Anish Bhardwaj, Shu Zhang, Han Yan +3
The search for quantum spin liquids (QSL) -- topological magnets with fractionalized excitations -- has been a central theme in condensed matter and materials physics. While theori…
Bell-state generation for spin qubits via dissipative coupling
Ji Zou, Shu Zhang, Yaroslav Tserkovnyak
We theoretically investigate the dynamics of two spin qubits interacting with a magnetic medium. A systematic formal framework for this qubit-magnet hybrid system is developed in t…
Flavors of Magnetic Noise in Quantum Materials
Shu Zhang, Yaroslav Tserkovnyak
The complexity of electronic band structures in quantum materials offers new charge-neutral degrees of freedom stable for transport, a promising example being the valley (axial) de…
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…
