Quantum Computational Complexity - Cheriton School of Computer
... The inherent difficulty, or hardness, of computational problems is a fundamental concept in computational complexity theory. Hardness is typically formalized in terms of the resources required by different models of computation to solve a given problem, such as the number of steps of a deterministic ...

Quantum Hall Effects and Related Topics International Symposium
... Electrons moving in a periodic electric potential form Bloch energy bands where the mass of electrons are effectively changed. In a strong magnetic field, the cyclotron orbits of free electrons are quantized and Landau levels forms with a massive degeneracy within. In 1976, Hofstadter showed that for ...

Transport Properties of Interacting Edge Modes in 2D Topological
... Recently, there has been a lot of interest in the phyics of systems called topological insulators, which includes the so called quantum spin Hall insulators. These are materials, which are insulating in the bulk, but support gapless modes on the boundary. The presence of time-reversal symmetry in th ...
