Controlling Magnetic Anisotropy Using Isotropic Cation Substitution
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.
George Rowlands, 1932-2021
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.
More than 50 hadrons discovered at the LHC
Ever more new hadrons are being observed at the LHC, including several unexpected discoveries of tetraquark and pentaquark states.
Loschmidt echo singularities as dynamical signatures of strongly localized phases
Quantum localization (single-body or many-body) comes with the emergence of local conserved quantities called l-bits—whose conservation is precisely at the heart of the absence of transport through the system. And in the just published article New J. Phys. 23, 1 (2021), d.in/dD9FqNy), two Warwick physicists and an international team show that these l-bits bear a dramatic universal signature, accessible to state-of-the-art quantum simulators, in the form of periodic cusp singularities in the Loschmidt echo following a quantum quench from a Néel/charge-density-wave state.
