Araki Cohomology of the de Sitter Scalar Discrete Series
Maryam Bajalan, Jean-Pierre Gazeau, Hamed Pejhan +1
Building on the recently established de Sitter (dS)-covariant indecomposable Krein realization of the scalar discrete-series unitary irreducible representations , $p=1,2,\…
Bi-Oriented Interlaced Matrix Multiplication and an Operator Factorisation of the Quantum Harmonic Oscillator
Jean-Pierre Gazeau
We introduce a bi-oriented interlaced matrix product on matrices over a unital, possibly non-associative algebra, extending a matrix mnemonic for Cayley--Dickson doubli…
Earth as a Closed Life-Support System: Finite Buffers, Dynamical Thresholds, and Planetary Sustainability
Jean-Pierre Gazeau
Earth is nearly closed with respect to matter but open with respect to energy. We formulate planetary sustainability as a minimal nonequilibrium dynamical problem for coupled finit…
Wigner negativity and stellar rank for SU(1,1) states
A. B. Klimov, A. Muñoz, G. Leuchs +2
Quasiprobability distributions for systems endowed with SU(1,1) dynamical symmetry have received surprisingly little attention, despite the central role of this symmetry in two-pho…
de Sitter Scalar Discrete Series: Gupta-Bleuler Structure and Holography
Maryam Bajalan, Jean-Pierre Gazeau, Hamed Pejhan
We show that scalar discrete-series unitary irreducible representations (UIRs) () of the de Sitter (dS) group admit a dS-covariant Krei…
Infrared Spectral Gap in a Gluonic Dark Sector and the Galactic Acceleration Scale
Gilles Cohen-Tannoudji, Jean-Pierre Gazeau, Hamed Pejhan +1
We further develop a trace-anomaly-motivated gluonic scenario in which cold dark matter (CDM) is modeled as a long-lived color-singlet Bose-Einstein condensate seeded at the QCD co…
