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.
Ever more new hadrons are being observed at the LHC, including several unexpected discoveries of tetraquark and pentaquark states.
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.
Videos of the workshop "Theoretical and Mathematical Physic in Paris, Singapore and Warwick" now online
Theoretical and mathematical physicists at Cergy, Singapore and Warwick have many common research interests, for example mathematical and computational methods, artificial intelligence, quantum physics in all its manifestations, etc., and potential for future projects for collaboration. In order to communicate these better to each other, we met virtually for a 2-half-day workshop in July 2020 with selected presentations.
Researchers were free to present in-progress projects, talk about completed papers or give overview talks of their research interest. Similarly, PhD and MSc level students were encouraged to present their work, either as a talk or as a virtual poster.
Have a look at the vidoes to see if some of the work would be of interest to you and feel free to contact colleagues in Cergy, Singapore and of course also at Warwick.
Professor Sandra Chapman (CFSA) awarded the 2020 Ed Lorenz Lecture for the Fall Meeting of the American Geophysical Union (AGU) – which will be one of the world’s largest virtual scientific conferences [1-17 December 2020]. The Ed Lorenz Lecture is given on topics in non-linear physics across all for space and geophysics. Lecture will explore how advances in fundamental physics can help quantify space weather risk.
The LHCb collaboration has announced the discovery of a new particle, which appears to be the first observation of a tetraquark composed of four different types of quark.
