Quantum and Condensed Matter Theory
Quantum mechanics is one of pillars of modern physics and the School of Physics at UCD hosts an active theory group of researchers working at the forefront of quantum science. We lead UCD's Centre for Quantum Engineering, Science, and Technology. Our interests range from the foundations of quantum mechanics to the modelling and realisation of novel quantum materials.
