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…

Generalized conformal quantum mechanics as an ideal observer in two-dimensional gravity
Archi Banerjee, Tanay Kibe, Martín Molina +1
We obtain an action for a generalized conformal mechanics (GCM) coupled to Jackiw-Teitelboim (JT) gravity from a double scaling limit of the motion of a charged massive particle in…
