Research
I'm generally interested in topological phases of matter, especially in transport and quantum anomalies in topological semimetals. Most of my previous research resolved around these topics. Currently, I shift my main focus on interacting phases of matter, in particular, on the Sachdev-Ye-Kitaev model and manifestations of its symmetry classification. Most recently, I worked on:
- Strain-induced phenomena in Weyl semimetals
- Disorder in correlated electron systems
- Anomalies in topological semimetals: beyond the chiral anomaly
I employ both numerical and analytical techniques to investigate transport, response functions, and symmetries in various topological and nontopological phases.
