On the Uniqueness of the Fock Quantization of the Dirac Field in the Closed FRW Cosmology
Advances in Mathematical Physics, 2018 The Fock quantization of free fields propagating in cosmological backgrounds is in general not unambiguously defined due to the nonstationarity of the space-time. For the case of a scalar field in cosmological scenarios, it is known that the criterion of

The analysis of complex phonetic elements in Bura and the syllable
Studies in African Linguistics, 1983 This paper examines those complex phonetic elements in Bura (and related languages such as Margi) which have been described by earlier scholars as unitary segments having a labial-alveolar double articulation.

Unitary massless representations of conformal superalgebras
Physics Letters B, 1986 Abstract Massless unitary irreducible representations of the conformal superalgebras SU(2, 2/ N ) are shown to be atypical representations. The existence of such representations appears restricted to N ⩽4 if the spin condition s ⩽2 is imposed on the states.

Journal of High Energy PhysicsThe relation between two branches of solutions (radiative and subradiative) of wave equations on Minkowski spacetime is investigated, for any integer spin, in flat Bondi coordinates where remarkable simplifications occur and allow for exact boundary-to ...

An Integral Representation of Standard Automorphic L Functions for Unitary Groups
International Journal of Mathematics and Mathematical Sciences, 2007 Let F be a number field, G a quasi-split unitary group of rank n. We show that given an irreducible cuspidal automorphic representation π of G(A), its (partial) L function LS(s,π,σ) can be represented by a Rankin-Selberg-type integral involving cusp ...

Quantifying the Unitary Generation of Coherence from Thermal Quantum Systems
Entropy, 2019 Coherence is associated with transient quantum states; in contrast, equilibrium thermal quantum systems have no coherence. We investigate the quantum control task of generating maximum coherence from an initial thermal state employing an external field ...
