Any Orthonormal Basis in High Dimension is Uniformly Distributed over the Sphere
Sheldon Goldstein, Joel L. Lebowitz, Roderich Tumulka +1
Let X be a real or complex Hilbert space of finite but large dimension d, let S(X) denote the unit sphere of X, and let u denote the normalized uniform measure on S(X). For a finit…
Elementary Proof for Asymptotics of Large Haar-Distributed Unitary Matrices
Christian Mastrodonato, Roderich Tumulka
We provide an elementary proof for a theorem due to Petz and Réffy which states that for a random unitary matrix with distribution given by the Haar measure on the unit…
Some Jump Processes in Quantum Field Theory
Roderich Tumulka, Hans-Otto Georgii
A jump process for the positions of interacting quantum particles on a lattice, with time-dependent transition rates governed by the state vector, was first considered by J.S. Bell…
Global Existence of Bell's Time-Inhomogeneous Jump Process for Lattice Quantum Field Theory
Hans-Otto Georgii, Roderich Tumulka
We consider the time-inhomogeneous Markovian jump process introduced by John S. Bell [Phys.Rep. 137, 49] for a lattice quantum field theory, which runs on the associated configurat…
