Energy transfer between localized emitters in photonic cavities from first principles
Swarnabha Chattaraj, Giulia Galli
Radiative and nonradiative resonant couplings between defects are ubiquitous phenomena in photonic devices used in classical and quantum information technology applications. In thi…
Designing Optically Addressable Nitrogen-Vacancy Centers in Ultra-Small Nanodiamonds: Insights from First-Principles Calculations
Arpan Kundu, Francesco Martinelli, Giulia Galli
Ultrasmall nanodiamonds (USNDs) are promising platforms for fluorescent and quantum sensing applications. Here we present first-principles electronic structure calculations of colo…
Nuclear Quantum Effects on the Electronic Structure of Water and Ice
Margaret Berrens, Arpan Kundu, Marcos F. Calegari Andrade +3
The electronic properties and optical response of ice and water are intricately shaped by their molecular structure, including the quantum mechanical nature of hydrogen atoms. In s…
Quantum Vibronic Effects on the Excitation Energies of the Nitrogen-Vacancy Center in Diamond
Arpan Kundu, Giulia Galli
We investigate the impact of quantum vibronic coupling on the electronic properties of solid-state spin defects using stochastic methods and first principles molecular dynamics wit…
First-Principle Investigation Of Near-Field Energy Transfer Between Localized Quantum Emitters in Solids
Swarnabha Chattaraj, Supratik Guha, Giulia Galli
We present a predictive and general approach to investigate near-field energy transfer processes between localized defects in semiconductors, which couples first principle electron…
