Modal Theory of Phase‐Modulated and Frequency‐Shifting Ring Cavities
Advanced Photonics Research, EarlyView.We present a theoretical and experimental characterization of the optical modes of dispersionless ring cavities with phase modulators or frequency shifters. Their response to arbitrary modulation acts as a filter for phase‐modulated modes that determine the optical output of passive resonators and lasers. This provides a general framework for analyzing

Non-classical correlations beyond Bell’s inequality violation in qubit-pairs with an intrinsic noise
Results in Physics, 2019 In this paper, we analytically explore two qubits interacting with a coherent harmonic oscillator field under intrinsic noise. The interaction of the uncorrelated two qubits with a harmonic oscillator initially in the superposition of coherent states ...

Submolecular‐Resolution Probing of Vibrational Anharmonicity Using Tip‐Enhanced Raman Spectroscopy
Angewandte Chemie, EarlyView.This work explores how tip‐enhanced Raman spectroscopy achieves submolecular resolution in detecting vibrational overtones and combination bands. This breakthrough reveals site‐specific anharmonicities and energy transfer pathways within single molecules, advancing chemical analysis with unprecedented spatial and spectral detail.

Quantum harmonic oscillators and thermalization
, 2021 We study a quantum harmonic oscillator undergoing thermalization. To describe the thermalization process, we generalize the Ermakov-Lewis-Riesenfeld (ELR) invariant method for the oscillator. After imposing appropriate conditions on the thermalization process, we introduce an ansatz equation that describes the time evolution effectively.

Advanced Photonics Research, EarlyView.Strong resonant amplification in polarization anisotropy in third harmonic generation (THG) response from isolated MoS2 disks with small structural ellipticity introduced during fabrication is reported. This is attributed to the high refractive index of the MoS2 disk that supports characteristic anapole resonances combined with the cubic dependence of ...

N‐Doped Nonalternant Molecular Bowl/Saddle Hybrids
Angewandte Chemie, EarlyView.N‐Doped molecular bowl/saddle hybrids were developed via core‐expansion synthetic strategy. Owing to the structural features containing both positive and negative curvatures, these molecules exhibit unique molecular dynamics, photophysical properties and multiple guest bindings. Abstract Herein, we report the straightforward synthesis and properties of

Quantum kicked harmonic oscillator in contact with a heat bath [PDF]
, 2016 We consider the quantum harmonic oscillator in contact with a finite temperature bath, modelled by the Caldeira-Leggett master equation. Applying periodic kicks to the oscillator, we study the system in different dynamical regimes between classical ...

Advanced Photonics Research, EarlyView.Self‐mixing interferometry is a powerful technique that brings together the exceptional sensitivity of phase measurements with the unequalled simplicity of the self‐mix configuration based on modulation of the cavity field induced by the return from the target. According to the selected measurand, displacement or vibration, and to the analog of digital
