The Mott transition as a topological phase transition
Sudeshna Sen, Patrick J. Wong, Andrew K. Mitchell
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 observa…

Fragility of the Kondo insulating gap against disorder: relevance to recent puzzles in topological Kondo insulators
Sudeshna Sen, N. S. Vidhyadhiraja, Eduardo Miranda +2
Kondo insulators are strongly correlated system in which a clean insulating gap emerges only at very low temperature due to many-body effects involving localized -electrons. How…
