Sensing with quantum light: a perspective

Nanophotonics, Volume 14, Issue 11, Page 1993-2003, June 2025.
Abstract I present my perspective on sensing with quantum light. I summarise the motivations and methodology for identifying quantum enhancements in sensing over a classical sensor. In the real world, this enhancement will be a constant factor and not increase with the size of the quantum probe as is often advertised.

Landau-Zener problem for energies close to potential crossing points

, 2004
We examine one overlooked in previous investigations aspect of well - known Landau - Zener (LZ) problem, namely, the behavior in the intermediate, i.e. close to a crossing point, energy region, when all four LZ states are coupled and should be taken into

Rate Constants and Energetics of the H2SiO + H Reaction System: RP‐VTST/MT and VRC Calculations

Journal of Computational Chemistry, Volume 46, Issue 14, May 30, 2025.
The decomposition of Silaformaldehyde (H2SiO) involves three reactions: H + H2SiO → H2 + HSiO (R1), H + H2SiO → H2SiOH (R2), and H + H2SiO → H3SiO (R3). Accurate energetics were calculated using ωB97X‐D and CCSD(T), and rate constants using CVT methods with multidimensional tunneling.

Non-planar corrections in ABJM theory from quantum M2 branes

Journal of High Energy Physics
The quantization of semiclassical strings in AdS spacetimes yields predictions for the strong-coupling behaviour of the scaling dimensions of the corresponding operators in the planar limit of the dual gauge theory.

On semiclassical dispersion relations of Harper-like operators

, 2004
We describe some semiclassical spectral properties of Harper-like operators, i.e. of one-dimensional quantum Hamiltonians periodic in both momentum and position.

Quantum scattering with semiclassical asymptotic motion

, 2018
Conventional scattering theory is incomplete in that it does not adequately describe the behaviour of the wave function at macroscopic distances from the scattering reaction volume. In scattering experiments particles are incident from sources at macroscopic distance and measured at macroscopic distance from the microscopic reaction volume.

Quantum Mechanics in Plasmonic Nanocavities: from Theory to Applications

Advanced Physics Research, Volume 4, Issue 4, April 2025.
Plasmonic nanocavities based on nanoparticle‐on‐mirror (NPoM) geometry provide a facile and versatile platform for quantum plasmonics and its applications. This review focuses on the fundamental theories of quantum plasmonics, its modeling and computation strategies, and its applications. It is suggested that the proper selection of material systems is

On non-planar ABJM anomalous dimensions from M2 branes in AdS4 × S 7/ℤ k

Journal of High Energy Physics
Planar parts of conformal dimensions of primary operators in U k (N) × U −k (N) ABJM theory are controlled by integrability. Strong coupling asymptotics of planar dimensions of operators with large spins can be found from the energy of semiclassical ...

Feynman-Kac formula for Levy processes and semiclassical (Euclidean) momentum representation [PDF]

, 2013
We prove a version of the Feynman-Kac formula for Levy processes and integro-differential operators, with application to the momentum representation of suitable quantum (Euclidean) systems whose Hamiltonians involve L\'{e}vy-type potentials.

Sourcing the Kerr Geometry

Fortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract The Kerr metric is a vacuum solution of the Einstein equations outside of a rotating black hole (BH), but what interior matter is actually rotating and sourcing the Kerr geometry? Here, a rotating exotic matter is described, which can source the Kerr geometry for the entire acceptable range of its spin parameter and be shown to saturate the ...
