Modeling Quantum Behavior in the Framework of Permutation Groups
Quantum-mechanical concepts can be formulated in constructive finite terms without loss of their empirical content if we replace a general unitary group by a unitary representation of a finite group.

Weil Representations of Unitary Groups
It is well known that the finite unitary group \(\text{U}_n(q)\), where \(q\) is a positive integral power of a prime \(p\), has a complex representation of degree \(q^n\). This representation may be normalized so that it has determinant \(1\) on each group element.

On a Simple Relation between Duffin-Kemmer-Petiau and Tzou Algebras
A simple link between βμ matrices of the Duffin-Kemmer-Petiau theory and ρμ matrices of Tzou representations is constructed. The link consists of a constant unitary transformation of the βμ matrices and a projection onto a lower-dimensional subspace.

On unitary representations of Jacobi groups.
This is a corrigendum to the author's article in [J. Reine Angew. Math. 409, 138-171 (1990; Zbl 0702.11027)]. This paper gives a new proof of Prop. 9.1 and its generalization. Our main result is that the holomorphic discrete series of a Jacobi group has a minimal \(K\)-type \(\delta\) with multiplicity one.

The statistical analysis of SAXS modelling data allows to identify the critical physicochemical parameters that have an impact on the phase behavior of crude sophorolipid batches. ABSTRACT The aqueous self‐assembly of raw sophorolipid mixtures has been studied by small angle x‐ray scattering (SAXS) to understand the impact of the composition ...

Low-dimensional representations of special unitary groups
We prove gap results for the low-dimensional representation of unitary groups in nondefining characteristics. More precisely, we give a lower bound for the third smallest degree of a nontrivial absolutely irreducible representation of the groups ...

Quantum Heat Current in Terahertz‐Driven Phonon Systems
We develop a quantum mechanical description of ultrafast thermodynamics on the example of a laser‐excited phonon mode. We show that the resulting quantum heat current exhibits non‐Markovian dynamics, which can be controlled by the pulse length. ABSTRACT The advent of high‐intensity ultrafast laser pulses has opened new opportunities for controlling and

Ambitwistors, oscillators and massless fields on AdS5
Positive energy unitary irreducible representations of SU(2,2) can be constructed with the aid of bosonic oscillators in (anti)fundamental representation of SU(2)L×SU(2)R that are closely related to Penrose twistors.
