... given by the trace h O i = Tr(Oρ). Our main interest will be in the magnetic moments m ~ k at site k of the chain. For convenience we ignore material-dependent factors and choose units such that m ~ k = h ~σk i. In the absence of the unitary part given by the spin chain Hamiltonian H, the non-unitar ...

Multiprobe quantum spin Hall bars
... are lower than their QSH counterparts. An interesting cross-over occurs at p = 0.5, where an equal number of channels are backscattered and transmitted. The QH and QSH resistances become equal and thereafter the QH resistance rises above the QSH one. In conclusion, we have studied multi-terminal QSH ...

Anatomy of quantum chaotic eigenstates
... dynamical systems we will focus on (mostly geodesic flows and maps on the 2dimensional torus), mentioning their degree of “chaos”. We also sketch the quantization procedures leading to quantum Hamiltonians or propagators, whose eigenstates we want to understand. We also mention some properties of th ...

Electric field inside a Hydrogen atom
... Electric flux is independent of exact radius and only depends on enclosed charge. If you increase the size of the sphere, the electric field gets smaller, but the area increases → electric flux stays constant Phys272 - Spring 14 - von Doetinchem - 105 ...

Renormalization and quantum field theory
... We give an overview of the construction of a perturbative quantum field theory from a Lagrangian. We start by translating some terms in physics into mathematical terminology. Definition 1. Spacetime is a smooth finite-dimensional metrizable manifold M, together with a “causality” relation 6 that is ...

Consequently, any term that has type !A should automatically also have type A. We say that !A is a subtype of A. The concept of a subtype also extends to composite types, for instan ...
