Analytical Solutions of the Driven Time‐Dependent Jaynes–Cummings Model

open access: yesAnnalen der Physik, EarlyView.
Following the great strides made in the last decade towards the control and tunability of physical parameters in cavity quantum electrodynamics, this study presents new solutions to the dynamics of the time‐dependent Jaynes–Cummings model with variable external classical fields acting on the two‐level system and the quantized field mode.

Minimal unitary representation of 5d superconformal algebra F(4) and AdS6/CFT5 higher spin (super)-algebras

open access: yesNuclear Physics B, 2015
We study the minimal unitary representation (minrep) of SO(5,2), obtained by quantization of its geometric quasiconformal action, its deformations and supersymmetric extensions.

Low‐Energy Atomic Scattering: S‐Wave Relation Between the Interaction Potential and the Phase Shift

open access: yesAnnalen der Physik, EarlyView.
The validity of the on‐shell approximation for s‐wave scattering is examined across one, two, and three dimensions using exactly solvable model interaction potentials. By comparing exact and approximate s‐wave components of the interaction potential, the analysis reveals that the approximation improves with increasing momentum and decreasing ...

The 4-CB algebra and solvable lattice models

open access: yesJournal of High Energy Physics, 2019
We study the algebras underlying solvable lattice models of the type fusion interaction round the face (IRF). We propose that the algebras are universal, depending only on the number of blocks, which is the degree of polynomial equation obeyed by the ...

From Triplet to Twist: The Photochemical E/Z‐Isomerization Pathway of the Near‐Infrared Photoswitch peri‐Anthracenethioindigo

open access: yesAngewandte Chemie International Edition, EarlyView.
The full photoisomerization mechanism of the all‐red‐light addressable peri‐anthracenethioindigo (PAT) has been decoded. Theory and transient absorption spectroscopy show that both E→Z$E\rightarrow Z$ and Z→E$Z\rightarrow E$ switching proceed via the triplet state.

Bundles of Banach algebras

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1994
We study bundles of Banach algebras π:A→X, where each fiber Ax=π−1({x}) is a Banach algebra and X is a compact Hausdorff space. In the case where all fibers are commutative, we investigate how the Gelfand representation of the section space algebra Γ(π ...

Algebraic foundations for qualitative calculi and networks

open access: yes, 2017
A qualitative representation $\phi$ is like an ordinary representation of a relation algebra, but instead of requiring $(a; b)^\phi = a^\phi | b^\phi$, as we do for ordinary representations, we only require that $c^\phi\supseteq a^\phi | b^\phi \iff c ...

Full‐order observer design for quadratic port‐controlled Hamiltonian systems

open access: yesAsian Journal of Control, EarlyView.
Abstract The full‐order observer design problem for a particular class of port‐controlled Hamiltonian systems is approached in this paper. The proposed full‐order observer scheme belongs to the structure preserving class of dynamic estimators as it preserves the natural stability properties of the approached class of systems that are useful for the ...
