Topological transitions in metals
Physical Review B, 2019 We investigate if a sharp topological transition in a metal with a large Fermi surface may be detected in transport measurements. In particular, we address if a skew scattering and a side jump on elastic disorder in the bulk of such a metal masks signatures of the topological transition.

The Mott transition as a topological phase transition [PDF]
Physical Review B, 2020 We show that the Mott metal-insulator transition in the standard one-band Hubbard model can be understood as a topological phase transition. Our approach is inspired by the observation that the mid-gap pole in the self-energy of a Mott insulator resembles the zero-energy spectral pole of the localized surface state in a topological insulator.

Electric field driven quantum phase transition between band insulator and topological insulator [PDF]
, 2009 We demonstrate theoretically that electric field can drive a quantum phase transition between band insulator to topological insulator in CdTe/HgCdTe/CdTe quantum wells.

Light‐Induced Quantum Anomalous Hall Effect on the 2D Surfaces of 3D Topological Insulators
Advanced Science, 2021 Quantum anomalous Hall (QAH) effect generates quantized electric charge Hall conductance without external magnetic field. It requires both nontrivial band topology and time‐reversal symmetry (TRS) breaking.
