Towards Gauging Time-Reversal Symmetry: A Tensor Network Approach

open access: yesPhysical Review X, 2015
It is well known that unitary symmetries can be “gauged,” i.e., defined to act in a local way, which leads to a corresponding gauge field. Gauging, for example, the charge-conservation symmetry leads to electromagnetic gauge fields.

On unitary representations of Jacobi groups.

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 1992
This is a corrigendum to the author's article in [J. Reine Angew. Math. 409, 138-171 (1990; Zbl 0702.11027)]. This paper gives a new proof of Prop. 9.1 and its generalization. Our main result is that the holomorphic discrete series of a Jacobi group has a minimal \(K\)-type \(\delta\) with multiplicity one.

A Higher-order poincaré ellipsoid representation for non-cylindrical vector beams

open access: yesDiscover Applied Sciences
The Higher-Order Poincaré Sphere (HOPS) provides a powerful geometrical tool for representing vector beams as points on the surface of a unitary sphere. Since a particular position on the surface represents any spatial mode regardless of its shape, this ...
