2024年3月7日 · Focusing on zone-center modes, we propose a method involving Hessian matrices and Berry curvature tensors in terms of both phonon and spin degrees of freedom, and describe a first-principles methodology for calculating these.

I am a Ph.D. student working with Prof. David Vanderbilt at Rutgers University. My research interest is mainly about topological quantum matters, including both model systems and real materials. I am particularly interested in the application of Berry …

2023年7月11日 · View a PDF of the paper titled Adiabatic dynamics of coupled spins and phonons in magnetic insulators, by Shang Ren and 4 other authors

After reviewing some elementary knowledge of the theory of a general class of second-order linear homogeneous ordinary differential equations, we introduce two basic Sturm theorems on the zeros of...

2023年2月21日 · In this Letter, we develop a first-principles method to calculate this velocity-force coupling in extended solids and show via the example of ferromagnetic that, due to the slow dynamics of the spins in the system, the assumption of adiabatic separation can result in large errors for splittings of zone-center chiral modes.
