Some remarks on the Quantum Hall Effect - IPhT
... This partition function was computed exactly for m = 1 in [17] with orthogonal polynomials (in section (5) these polynomials will be described explicitly). Here, in order to illustrate the emergence of the edge physics we look at it from a semi-classical point of view and limit ourselves to t << 1. ...

... VII. Collisions in Two or Three Dimensions Problem solving: 1. Choose the system. If it is complex, subsystems may be chosen where one or more conservation laws apply. 2. Is there an external force? If so, is the collision time short enough that you can ignore it? 3. Draw diagrams of the initial an ...

Computational complexity in electronic structure PERSPECTIVE

Those results have since been extended in many directions, but in this article we focus on the difficulty of computing the ground state energy of quantum Hami ...

The Basic Laws of Nature: from quarks to cosmos
... Fermions have unknown couplings to the Higgs. We determine the couplings from the fermion mass. B0 and W0 mix to give A0 and Z0. Three Higgs fields are ‘‘eaten’’ by the vector bosons to make longitudinal massive vector boson. Mass of W, mass of Z, and vector couplings of all fermions can be checked ...
