Harmonic expansions in solutions in d=11 supergravity with SU(3)×SU(2)×U(1) or SU(2)×SU(2)×SU(2)×(1) symmetry

Classical and Quantum Gravity, 1984
The spectrum of the scalar Laplacian on the SU(3)*SU(2)*U(1) invariant spaces introduced by Witten is calculated. Contrary is previous results in the literature, it is shown that the harmonics can carry non-zero triality representations of SU(3). Similar results hold also for spinor harmonics, and indeed the quark triplet representation can occur on ...

SU(2)  × SU(2) scalars in the enveloping algebra of SU(4)

Journal of Mathematical Physics, 1976
We build an integrity basis for the SU(2)  × SU(2) scalars belonging to the enveloping algebra of SU(4). We prove that it contains seven independent invariants in addition to the Casimir operators of SU(4) and SU(2)  × SU(2). We form a complete set of commuting operators by adding to the latter two linear combinations of the former the operators Ω and ...

Matrix elements of the labelling operators for SU(4) ⊃ SU(2) × SU(2)

Journal of Physics A: Mathematical and General, 1989
A matrix representation of the labelling operators of Moshinsky and Nagel (1963) and of Partensky and Maguin (1978) in the non-orthogonal Draayer basis of SU(4) is derived; this allows one to solve explicitly the missing label problem for the spin-isospin multiplets in the arbitrary SU(4) supermultiplets.

QuantumSU(2)-invariants dominate Casson'sSU(2)-invariant

Mathematical Proceedings of the Cambridge Philosophical Society, 1994
In 1988, E. Witten proposed an array of invariants (quantumG-invariants) for a 3-manifold associated with a compact simple Lie groupGbased on the quantum field theory [22]. N. Reshetikhin and V. Turaev [20] gave a mathematical approach to these invariants forG=SU(2) by using representations of the quantum groupUq(sl(2, ℂ)). See also [2, 11, 12, 14, 15,

Understanding Cooper Pairs through SU(2)/SO(2) and Generalizing SU(2)/SO(2) to SU(3)/SO(2)

SSRN Electronic Journal
This article explores how a mathematical tool called SU(2)/SO(2) helps us understand the behavior of Cooper pairs, tiny electron couples responsible for superconductivity. Copper pairs consist of two electrons with opposite spins bound together by vibrations in the material.
