2024

  • Siyu Chen successfully defends his PhD thesis. The work proposes a new computational method exploiting non-uniform grids to accelerate phonon and electron-phonon calculations. Using this method, Siyu also explores the properties of two-dimensional and three-dimensional topological materials, superconductors, and high pressure hydrides. Siyu will continue working in the Monserrat Lab as a Postdoctoral Research Associate to further develop our phonon and electron-phonon software. Looking forward to more exciting results!

2023

  • Arjun Ashoka successfully defends his PhD thesis. The work focuses on studying quantum processes in disordered materials combining experiment and theory. His experimental work develops new techniques for 3D ultrafast microscopy with which he investigates a range of quantum processes, from the formation of entangled states in an organic semiconductor to spin domain formation in halide perovskites. His theoretical work develops the foundation with which to study the sub-bandgap absorption tail in high performance semiconductors that arises from dynamic disorder through the presence of lattice vibrations. Arjun is now building his independent research career as a Junior Research Fellow at Trinity College Cambridge. Good luck!
