Entanglement spectrum of gapless topological phases: a case study with topological superconductors
Archi Banerjee, Meng Zeng
Using bulk gapless topological superconductors in both 1d and 2d as free fermion model examples, we demonstrate the power of subsystem correlation spectrum (the spectrum of correla…

Microscopic field theories of the quantum skyrmion Hall effect
Vinay Patil, Archi Banerjee, Ashley M. Cook
We construct effective field theories of the quantum skyrmion Hall effect from matrix Chern-Simons theory for electrons, corresponding to matrix dimension . We first conside…

Multiplicative Chern insulator
Archi Banerjee, Ashley M. Cook
We study multiplicative Chern insulators (MCIs) as canonical examples of multiplicative topological phases of matter. Constructing the MCI Bloch Hamiltonian as a symmetry-protected…
