Research Overview. The overarching goal of our group is to understand the interaction between electron spins in solid-state materials with excitons, phonons, and magnons, and use these interactions to dynamically control the material properties.

1. 2D magnetic semiconductor-based quantum transducer. My recent work demonstrated the first instance of magnon-exciton coupling in a magnetic semiconductor. This coupling is particularly exciting because exciton-coupled magnon may directly couple to a superconducting qubit with electric dipole moments. Conventional magnons only have magnetic dipoles and this requires magnonic material and qubit to share a microwave cavity. My hypothesis is that exciton-coupled magnon could provide a direct coupling to electric dipole moment in qubits.
2. Driving magnetic phase transitions using spin-phonon, magnon, and/or exciton interactions. When we think of magnetic phase transitions, we think about static changes such as temperature and/or pressure change. At the critical temperature, spins are fluctuating between order and disorder and their free energy landscape is rather flat. My hypothesis is that we can use the materials’ intrinsic spin interactions with other quasiparticles to dynamically induce magnetic phase transitions.
3. Symmetry breaking as design principles to induce spatial and temporal control of magnetization switching. Spin-orbit coupling allows a flow of angular momentum from lattice to spins. Changing the symmetry of orbital-orbital interactions in a lattice can create anisotropy in this transfer of angular momentum. My research goal is to use symmetry breaking as a way to generate directional spin-orbit torque to induce spatially and temporally varying magnetization. We can use this framework to create a new way of information processor or hardware approach to neural networks.

Experimental tools. In our lab, we will develop both frequency and time-domain spectroscopy i.e. 1. Brillouin light scattering (BLS), 2. Optical and RF based pump-probe spectroscopy. We will probe spatially and temporally changing magnetization in 2D materials + 2D materials-based devices.

My official start date is January 1st, 2024. Based on my research interest, I think anyone with one or more skillsets of pump-probe optical spectroscopy and microscopy, magnetic resonance spectroscopy (specifically, familiar with RF sources and waveguide fabrication), and 2D materials stacking will greatly suit my group. It will be a rich experience where you will be able to build optical and RF-based spectroscopy tools and also make use of one of the best cleanroom facilities at Cornell!
