We investigate magnetization-reversal processes in half-metallic epitaxial films of La0.67Sr0.33MnO3 on SrTiO3 (110) substrates. At 150 K, major-loop magnetization reversal (MLMR) occurs beyond minor-loop switching fields, implying that MLMR is limit...

Alterations in grey matter volume (GMV) and cortical thickness (CT) in Crohn’s disease (CD) patients has been previously documented. However, the findings are inconsistent, and not a true representation of CD burden, as only CD patients in remission...

A ‘Dynamic Kibble’ mass balance for the undergraduate physics teaching laboratory (2022)
Journal Article

We investigate the dynamics of a noninteracting spin system, undergoing coherent Rabi oscillations, in the presence of stochastic resetting. We show that resetting generally induces long-range quantum and classical correlations both in the emergent d...
