Melvin M. Vopson

Associate Professor of Physics, University of Portsmouth

Dr Melvin M. Vopson is an Associate Professor of Physics at the University of Portsmouth. His previous appointments include two postdoctoral fellowships at the University of York, senior R&D scientist at Seagate Technology (a world leading high-tech company) and over six years as Higher Research Scientist at the National Physical Laboratory.
Melvin's major scientific contributions are in the fields of solid state caloric effects, thin film growth technologies, multiferroic materials and their applications, optical techniques of characterisation of solids, development of novel metrologies and innovations based on ferroic materials, theoretical studies of non-equilibrium phenomena, fundamental physics, and information physics.
Melvin developed new optical techniques for the characterization of solids, novel metrologies for multiferroic materials, a non-equilibrium theory of polarization reversal in ferroelectrics, and novel technologies for digital memories, including the discovery of a 4-state anti-ferroelectric memory effect, the discovery of the multicaloric effect in multiferroic materials, the discovery of the mass-energy-information equivalence principle, or the 5th state of matter, and the discovery of the second law of infodynamics.
