The Theory of Nanophotonics Group at the Donostia International Physics Center (DIPC) in San Sebastián (Spain) offers a fully funded PhD position to explore how light-matter interactions at the nanoscale can push the boundaries of nanophotonic-based quantum technologies.
This position offers a unique opportunity to dive deep into the theory behind quantum nanophotonic platforms, working in a world-class research environment, and developing realistic models that connect directly with experimental efforts.
Project Overview
The PhD will focus on the theoretical study of nanoscale photon–matter interactions, especially the coupling between quantum emitters (such as organic molecules or quantum dots) and their interaction with optical nanoresonators in advanced quantum nanophotonic architectures.
These hybrid systems are crucial for generating and manipulating non-classical light, entangled states, and other resources for quantum technologies and molecular spectroscopy. The candidate will employ and develop cavity quantum electrodynamics (c-QED) models, enriched when needed by:
-First-principles calculations of excitonic and vibrational responses to feed c-QED Hamiltonians.
-Classical simulations of nano-optical structures to obtain the nanoresonator properties.
The generated states will be characterized through analysis of properties such as quantum correlations (color-blind and frequency-resolved), entanglement, and purity. The ultimate goal is to build increasingly realistic and predictive theoretical models of light-matter interactions at the nanoscale to support and guide experimental research in rapidly evolving fields such as molecular quantum optomechanics or nanophotonic-enhanced entangled photon generation.
The group
The thesis will be supervised by Javier Aizpurua and Ruben Esteban in the Theory of Nanophotonics Group, which is based at DIPC and the Centro de Física de Materiales (CFM) in San Sebastián. The group has pioneered studies of quantum effects in nanoscale optical systems, with current interest in the use of nanophotonics for quantum technologies, field-enhanced spectroscopy, and microscopy.
