80 Years of Professor Wigner's Seminal Work "On Unitary Representations of the Inhomogeneous Lorentz Group"

, 2021
It is perhaps the most fundamental principle of Quantum Mechanics that the system of states forms a linear manifold,1 in which a unitary scalar product is defined.2 The states are generally represented by wave functions3 in such a way that φ and constant

On the Unitary Binary Group [PDF]

open access: possibleSoutheast Asian Bulletin of Mathematics, 2001
The author investigates the unitary binary group \(\beta(n)\) over the algebra of real binary numbers, shows that this algebraic variety is rational and has \(n^2\) parameters, and gives a parametrical rational representation of this variety.

Unitary group adapted state-specific multi-reference coupled cluster theory: formulation and pilot numerical applications.

Journal of Chemical Physics, 2012
We present the formulation and the implementation of a spin-free state-specific multi-reference coupled cluster (SSMRCC) theory, realized via the unitary group adapted (UGA) approach, using a multi-exponential type of cluster expansion of the wave ...

Preservers of unitary group or equivalence by unitaries

Linear Algebra and its Applications, 2022
Abstract We give the complete description of bijective real-linear transformations on B ( H ) , the algebra of all bounded linear operators on an infinite-dimensional complex Hilbert space H , where every unitary U ∈ B ( H ) is mapped to a unitary ϕ ( U ) .
