Triplet Spintronics
Theme and goal
Superconducting spin-polarized triplets carry coherent quantum information. A component of their correlation does not decay in either ferromagnets or superconductors, even with impurities. This makes them a primary candidate for low- dissipation information transport in spintronics. We examine the interplay of magnetism and superconductivity in emerging spintronic systems, using theoretical and numerical techniques.
Key questions
Our research considers atypical geometries and model setups for examining the conversion mechanisms, manipulation and detection of superconducting singlets and triplets in spintronic devices, including magnets. We primarily consider the effect of curvature and/or strain,
as well as cavity-mediated effects, which may enable new superconducting spintronic device design and control.

Quantum Magnetism and Ultrafast Phenomena
Theme and goal
Our group conducts fundamental research across a broad range of theoretical and computational condensed matter physics, including quantum spintronics and magnetism (topological magnetic textures, superconducting spintronics, and neuromorphic spintronics); quantum transport
phenomena; topological phases of quantum matter; ultrafast and nonequilibrium phenomena; and quantum field-theory of many-body systems. Our goal is to understand and engineer emergent and exotic phenomena in novel quantum materials, such as 2D magnetic materials and topological quantum materials. We are also interested in investigating potential application of these phenomena in quantum technology. Novel quantum materials have exotic and interesting behaviours. For example, in 2D systems, quantum fluctuations and interactions are usually strong and cannot be neglected. On the other hand, in novel 3D topological materials, such as Weyl semimetals, emergent low-energy massless quasiparticles provide a testbed for investigating new phenomena beyond conventional relativistic quantum field theory and the Landau Fermi liquid paradigm. Developing theories to predict and explain exotic equilibrium and nonequilibrium states of novel quantum materials with an ultimate application beyond the state-of-the-art quantum devices are among our goals.
Key questions
The interplay between charge, spin, orbital, and lattice degrees of freedom, along with hybridization and such as magnons, spinons, phonons, and plasmons, drives a wide range of emergent phenomena in quantum materials. Understanding these phenomena at the microscopic level is a fundamental challenge in theoretical physics, requiring advanced analytical and computational techniques. Our research aims to uncover the role of quantum and thermal fluctuations in stabilizing nontrivial magnetic phases, exploring exotic transport properties, and discovering novel functional intelligent materials and exotic phases of matter.
