Quantum Spin Hall Effect and Topological Insulator
... fraction respectively. In 2000s, researchers found a new class of topological states, which is topologically distinct from all other known states of matter including quantum Hall effect. They call it quantum spin Hall effect. It is a state of matter proposed to exist in special two-dimensional semic ...

Homework #2 Solutions Version 2
... / The electric field at the center of the square is the sum of the electric fields due to the four charges; and as is the case with Coulomb’s Law, the “tricky” part is to find the vector ~r for each. For example, ~r1 is the vector from q1 to the center, which can be gotten by moving a distance 21 a ...

SEQUENTIALLY INDEPENDENT EFFECTS 1. Introduction
... two measurements M1 , M2 cannot be performed simultaneously so they are usually executed sequentially. Thus, they are either executed in the order (M1 , M2 ) or (M2 , M1 ). We may think of (M1 , M2 ) as a sequential measurement in which M1 is measured first and M2 second. As is frequently done, both ...
