A General Criterion of Quantum Integrability Accommodating Central Charges and Anomalies
P. P. Divakaran
A simple quantum generalisation of the Liouville-Arnold criterion of classical integrability is proposed: A system is quantum-integrable if it has an abelian Lie group of Wigner sy…

Heisenberg Groups in the Theory of the Lattice Peierls Electron: the Irrational Flux Case
P. P. Divakaran
It is shown that the quantum mechanics of a charged particle moving in a uniform magnetic field in the plane (Landau) or on a planar lattice (Peierls) is described in all detail by…
