Dr Mircea Bejan is a Postdoctoral Research Assistant in theoretical physics within the Theory & Simulation of Condensed Matter Group in the Department of Physics, King's College London.

Previously, he completed his PhD at the University of Cambridge, conducting research under Professor Benjamin Béri within the TCM Group at the Cavendish Laboratory. Before that, he obtained an MMathPhys and a BA in Physics at the University of Oxford.

Research

Dr Bejan explores the interplay between systems with many particles, such as electrons and nuclei, and quantum computers, whose building blocks are qubits. The overarching aim of his research is to understand new phases of matter using quantum simulators and to determine whether these devices are the most resource-efficient means of simulating quantum many-body dynamics.

He is investigating a broad range of topics at the intersection of condensed matter and quantum information theory using both pen-and-paper and numerical techniques, with a focus on non-equilibrium quantum dynamics. These topics include:

* Phase transitions in the classical simulability of quantum dynamics

* Generalised thermalisation phenomena and the dynamics of open systems

* Quantum error correction

* Hybrid quantum-classical simulation protocols for characterising phases of many-body systems
