International Journal of Chemical Kinetics, EarlyView.ABSTRACT Based on a recently developed full‐dimensional analytical potential energy surface, named PES‐2024, which was fitted to high‐level ab initio calculations, three different kinetic theories were used for the computation of thermal rate constants: variational transition state theory (VTST), quasi‐classical trajectory theory (QCT) and ring polymer

Laser &Photonics Reviews, EarlyView.Harnessing light–sound interaction in photonic integrated circuits can enable many classical and quantum applications on a chip. By utilizing bound states in the continuum for ultralow‐loss waveguiding, highly efficient intramodal and intermodal acousto‐optic modulation is demonstrated on an etchless lithium niobate integrated platform in the ...

Discrete Chiral Ballistic Polariton Laser
Laser &Photonics Reviews, EarlyView.Planar microcavities in the strong light–matter coupling regime exhibit exciton‐polariton modes with a strong chiral response toward circularly polarized light. This feature is exploited alongside inherent spin‐orbit coupling of cavity light to generate giant discrete optical vortices in polygonal arrays of exciton‐polariton condensates.

1 PHz of Coherent Bandwidth from a Compact Fiber Device
Laser &Photonics Reviews, EarlyView.A coherent comb spectrum with an unprecedented bandwidth of 1 PHz, spanning from the deep ultraviolet (280 nm) to the mid‐infrared (2700 nm), is generated by a compact fiber device. The integrated, novel pulse purification technology enables broadband dispersion control and the synthesis of low‐noise, single‐cycle near‐infrared pulses with a clean ...

The modified airy function approximation applied to the double-well potential
AIP AdvancesThe single harmonic oscillator and double-well potentials are important systems in quantum mechanics. The single harmonic oscillator is the paradigm in physics and is taught in nearly all beginner undergraduate classes, while the double-well potential ...

The One‐Dimensional Coulomb Hamiltonian: Properties of Its Birman–Schwinger Operator
Mathematical Methods in the Applied Sciences, EarlyView.ABSTRACT The objective of the present paper is to study in detail the properties of the Birman–Schwinger operator for a self‐adjoint realization of the one‐dimensional Hamiltonian with the Coulomb potential, both when the Hamiltonian is defined only on ℝ+$$ {\mathbb{R}}_{+} $$ and when it is defined on the whole real line.
