CSP - INTERNATIONAL WORKSHOP ON EMERGENT PHENOMENA IN QUANTUM HALL SYSTEMS
Abstract
The remarkable progress in semiconductor technology has enabled an amazing and rapidly expanding array of electronic devices. However, it is becoming increasingly clear that in future information processing applications, synergistic innovations in materials and devices based on new physical principles will be a key to achieving new levels of performance. While desirable attributes of devices are high speed, high density, and low-voltage operation, device physics sets fundamental limits and forces trade-offs on the integration of all desirable attributes into one device element. It is fairly clear that there is a need to think of information processing in a fundamentally different way. In the last 10 years there has been a paradigm shift in ideas of physics based on topology of condensed matter physics. The implication of topological aspects is primarily on two key fronts 1. Topological insulators 2. Topological protected states Topological insulators 1,2 are of immense interest as they offer platforms where electronic transport could be realized without any dissipation; the technological implications are immense. Experiments have already demonstrated that in topological insulators currents flow on the 2D surfaces of 3D materials. The idea of topological insulators has led to a new way of classifying electronic materials in solid state physics. These ideas of topological physics all emanated from experiments of quantum Hall physics 3,4. Quantum computing5 is another area where rapid progress is being made. However, the significant challenge is dephasing of the qubits due to interaction with the environment. However, one way to get around these problems is to make qubits that are topologically protected. This in effect can be achieved by entangled states. One of the way to realize topological protection is by realizing Majorana fermions6 in condensed matter systems.7Ð10 In addition new systems like Weyl semimetals have extended our understanding of topology in wide variety of systems 11,12. This workshop on Emergent Phenomena in Quantum Hall Systems (EPQHS) is 6th of the series. The previous EPQHS meetings have been held at Taos (New Mexico), Penn State, Luca (Italy), Beijing, and Weizmann. In the spirit of the previous meetings, this workshop will feature exciting new developments in quantum Hall as well as other topological systems. This invited speakers are leading experts in solid state physics and have led the pioneering research in the main theme of this workshop. The deliberations here will bring out recent developments and explore new schemes for harnessing topologically relevant solid state systems.
