Professor Nori’s research group works on condensed matter theory, quantum computing, and nonlinear collective dynamics in complex systems. Of particular interest are quantum computing and scalable quantum computing circuitry using superconducting qubits. Extensive work has been done studying transport phenomena of vortices, electrons, phonons, and grains in systems that have disorder and/or reduced dimensionality. Examples of these include confined geometries (such as films, slabs, wires, networks), multilayers, aperiodic, quasicrystalline, and disordered media.
Professor Nori’s research group uses numerical and analytical techniques to make theoretical predictions which can be verified experimentally, and they often collaborate with experimental groups. Specific problems they have studied in the past include: dynamics of superconducting vortices in disordered media; nonlinear threshold dynamics, collapses, avalanches, cascades and instabilities in granular and superconducting systems; magnetic and thermal properties of highTc materials; hole dynamics and other properties of quantum antiferromagnets; phonon and electron transport in quasicrystalline and other aperiodic systems; acoustic interference and phonon localization; quantum squeezed states, quantum fluctuations, and quantum noise control in solids, as well as quantum interference due to electron motion in magnetic fields in a variety of systems (including superconducting wire networks and Josephson junction arrays). Under certain circumstances, several of these apparently unrelated systems exhibit interesting complex nonlinear dynamics when driven to the threshold of instability.
Professor Nori is a Fellow of the American Physical Society and also a Fellow of the UK’s Institute of Physics.
