Chern-Simons theory and atypical Hall conductivity in the Varma phase
N. Menezes, C. Morais Smith, Giandomenico Palumbo
In this letter, we analyze the topological response of a fermionic model defined on the Lieb lattice in presence of an electromagnetic field. The tight-binding model is built in te…

Momentum-Space Cigar Geometry in Topological Phases
Giandomenico Palumbo
In this paper, we stress the importance of momentum-space geometry in the understanding of two-dimensional topological phases of matter. We focus, for simplicity, on the gapped bou…

Excitonic gap generation in thin-film topological insulators
N. Menezes, C. Morais Smith, Giandomenico Palumbo
In this work, we analyze the excitonic gap generation in the strong-coupling regime of thin films of three-dimensional time-reversal-invariant topological insulators. We start by w…
