Generalized quadratic commutator algebras of PBW-type
Ian Marquette, Luke Yates, Peter Jarvis
In recent years, various nonlinear algebraic structures have been obtained in the context of quantum systems as symmetry algebras, Painlevé transcendent models and missing label pr…
Quasicharacters, recoupling calculus and costratifications of lattice quantum gauge theory
P. D. Jarvis, G. Rudolph, M. Schmidt
We study the algebra of invariant representative functions over the N-fold Cartesian product of copies of a compact Lie group G modulo the action of conjugation by the diagonal sub…
A class of quadratic deformations of Lie superalgebras
Peter Jarvis, Gerd Rudolph, Luke Yates
We study certain Z_2-graded, finite-dimensional polynomial algebras of degree 2 which are a special class of deformations of Lie superalgebras, which we call quadratic Lie superalg…
The molecular asymmetric rigid rotor Hamiltonian as an exactly solvable model
P. D. Jarvis, L. A. Yates
Representations of the rotation group may be formulated in second-quantised language via Schwinger's transcription of angular momentum states onto states of an effective two-dimens…
