Ashvin Vishwanath is a Theoretical Physicist specializing in the study of Condensed Matter. Of late, his work has increasingly utilized ideas from information theory and quantum entanglement to study and classify novel phases of matter.

We have found novel magnetic phases, stabilized (paradoxically) by quantum or thermal fluctuations; and new kinds of phase transitions. This idea could potentially explain many of these anomalies, although unambiguous experimental evidence for this is still lacking.

Remarkably, this allows for a (generically) continuous transition between states of very different symmetry, e.g. However, materials like the high temperature cuprate superconductors, frustrated magnets and heavy fermion systems where interactions between electrons are particularly important, show many phenomena that are strikingly unconventional.

Fa Wang and A. Vishwanath “Spin Liquid States on the Triangular and Kagome Lattices: A PSG Analysis of Schwinger Boson States” Phys Rev. Phys. 377. 108 , 046602 (2012)] Fluctuating Superconductivity: When superconductivity is destroyed by thermal or quantum fluctuations – its presence may still be felt in different ways, for example in anomalies in the electrical or thermal conduction properties of the system, or in more subtle signatures such as the Nernst effect. Unconventional Quantum Phase Transitions: Recently, it has become clear that quantum phase transitions can also exhibit fractionalization, although the phases on either side of the transition are perfectly conventional.
