Edge States and Entanglement Entropy
A. P. Balachandran, L. Chandar, Arshad Momen
It is known that gauge fields defined on manifolds with spatial boundaries support states localized at the boundaries. In this paper, we demonstrate how coarse-graining over these…
Noncommutative Lattices as Finite Approximations and Their Noncommutative Geometries
A. P. Balachandran, G. Bimonte, E. Ercolessi +4
Lattice discretizations of continuous manifolds are common tools used in a variety of physical contexts. Conventional discrete approximations, however, cannot capture all aspects o…
Chern-Simons Duality and the Quantum Hall Effect
A. P. Balachandran, L. Chandar, B. Sathiapalan
In previous work on the quantum Hall effect on an annulus, we used duality transformations on the action describing edge excitations to generate the Haldane hierar…
Edge States in Canonical Gravity
A. P. Balachandran, L. Chandar, Arshad Momen
It is well-known that gauge fields defined on manifolds with spatial boundaries support states localized at the boundary. In this talk, we show how similar states arise in canonica…
TOPOLOGY CHANGE AND QUANTUM PHYSICS
A. P. Balachandran, G. Bimonte, G. Marmo +1
The role of topology in elementary quantum physics is discussed in detail. It is argued that attributes of classical spatial topology emerge from properties of state vectors with s…
