COMMUTANTS AND DOUBLE COMMUTANTS OF REFLEXIVE ALGEBRAS
The author studies the commutant and the double commutant of the algebra \(\text{alg }{\mathcal L}\) of all bounded operators on a Banach space \(X\) leaving invariant each member of a lattice \({\mathcal L}\) of subspaces of \(X\). For example, he proves that when \({\mathcal L}\) is the pentagon subspace lattice, then the only operators commuting ...

Seniority‐Zero Quadratic Canonical Transformation Theory
We construct a unitary transformation of electronic Hamiltonians using quadratic canonical transformation theory, choosing the transformation to minimize the non‐seniority‐zero elements of the transformed Hamiltonian. This allows us to add dynamic correlation to the static correlation inherent in orbital‐optimized doubly‐occupied (seniority‐zero ...

Multi‐Mode Deep Strong Coupling in a Multi Quantum Well Fabry–Perot Cavity
Multi‐mode deep‐strong coupling is demonstrated in a 166‐well heterostructure that acts as a Fabry–Perot cavity. Even cavity modes couple strongly to the cyclotron resonance, producing large vacuum Rabi splittings and a rich polaritonic spectrum captured by a full Hopfield model.

Dynamics of the Commutator Operator
Linear dynamics is a rapidly evolving area of operator theory, however the only results related to the dynamics of the commutator operators have hitherto been on the characterisation of the hypercyclicity of the left and right multiplication operators.

On commutator socle-regular Abelian p-groups
We define the notion of a commutator socle-regular Abelian p-group. After establishing some crucial properties of commutator socle-regularity, we investigate its relationship with socle-regularity, strong socle-regularity and projection socle ...

Early microglial response to amyloid plaques drives sleep loss in Alzheimer's disease
Abstract INTRODUCTION Sleep disruption is an early feature of Alzheimer's disease (AD), but the cellular mechanisms linking amyloid pathology to sleep loss remain unclear. METHODS Electroencephalography/electromyography (EEG/EMG) recordings, quantitative EEG analysis, and sleep deprivation were performed in APPswe/PSEN1dE9 (APP/PS1) mice at different ...

Relative commutator theory in varieties of Ω-groups
We introduce a new notion of commutator which depends on a choice of subvariety in any variety of Ω-groups. We prove that this notion encompasses Higgins’s commutator, Fröhlich’s central extensions and the Peiffer commutator of precrossed ...
