SU(2) and SU(1,1) interferometers
Physical Review A, 1986A Lie-group-theoretical approach to the analysis of interferometers is presented. Conventional interferometers such as the Mach-Zehnder and Fabry-Perot can be characterized by SU(2). We introduce a class of interferometers characterized by SU(1,1). These interferometers employ active elements such as four-wave mixers or degenerate-parametric amplifiers

The SU(4) ⊃ SU(2) ⊗ SU(2) chain
Journal of Mathematical Physics, 1978We consider the physical SU(4) ⊃ SU(2) ⊗ SU(2) chain. With the help of the three vectors (Sα, Ti, Qαi), (VαS, VtT, VαiQ), (WSα, WiT, WαiQ) we can easily write the three fundamental invariants I2, I3, I4; the two operators Ω and Φ (eigenvalues ω and φ) of Moshinsky and Nagel [Phys. Lett.

SU(2) × SU(2) scalars in the enveloping algebra of SU(4)
Journal of Mathematical Physics, 1976We 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 ...

Wigner coefficients for SU(6) ⊇ SU(3) ⊗ SU(2)
Journal of Mathematical Physics, 1979A technique for evaluating the Wigner coeficients for SU(6) with the physically interesting subgroups SU(3) ⊗SU(2) is outlined. Coefficients appropriate for coupling a single quark to a many quark wavefunction are tabulated for functions of nine or fewer quarks.

A bibliographic review of Su Shi, Su Shih 苏轼 (1037–1101), known also as Su Dongpo 苏东坡 or by his given name Su Zizhan 苏子瞻, must be multifaceted because, unlike Chinese figures who are known primarily for their poetry, he was recognized as a scholar-official whose literary works referenced earlier philosophical, literary, and historical writings ...

SU(2) and SU(1,1) phase states
Physical Review A, 1990Phase operators and phase states are introduced in the Hilbert space ${H}_{2j+1}$ associated with the SU(2) group. The phase operators obey the SU(2) algebra and play a dual role to the standard angular-momentum operators. A finite Weyl group plays a fundamental role in those ideas.

Supersymmetric Savvidy state for SU(2), SU(3), and SU(4)
Physical Review D, 1983The Savvidy ansatz of a covariantly constant background field in a Yang-Mills theory is used to calculate the one-loop quantum correction to the effective energy density in a supersymmetric gauge theory. This is done, with matter fields included, for the gauge groups SU(2), SU(3), and SU(4).
