What happens at the molecular lever when a photon hits the eye or light shines on a leaf?
Physical processes occurring on nanometre length scales and femtosecond time scales typically undergo complex dynamics involving multilevel quantum systems. Understanding such complex quantum dynamics is a major open challenge. Foremost among them is the dimension of the Hilbert space involved, which determines the number of parameters necessary for understanding the dynamics. This is typically done by fitting models of various degrees of sophistication to experimental data.
Study reveals a novel form of symmetry breaking driven by chemical intervention: an anisotropic change in magnetic properties is induced by ionic substitution of an isotropic species.
It is with great sadness we announce that Professor George Rowlands passed away on 3rd April 2021. George contributed enormously to the life of the Physics Department over a period of more than 50 years and his presence will be acutely missed by all who knew him.
Ever more new hadrons are being observed at the LHC, including several unexpected discoveries of tetraquark and pentaquark states.
