Embeddings and time evolution of the Schwarzschild wormhole
Einstein-Rosen bridge Schwarzschild wormhole embedding
2011/10/9
Abstract: We show how to embed spacelike slices of the Schwarzschild wormhole (or Einstein-Rosen bridge) in R^3. Graphical images of embeddings are given, including depictions of the dynamics of this ...
Adiabatic Theorem for Discrete Time Evolution

2011/10/8
Abstract: A proof of the adiabatic theorem for quantum systems whose time evolution proceeds along discrete time, e.g., quantum maps and quantum circuits, is shown.
A commonly adopted relational account of time evolution in generally-covariant systems, and more specifically in quantum cosmology, is argued to be unsatisfactory, insofar as it describes evolution re...
Macroscopic time evolution and MaxEnt inference for closed systems with Hamiltonian dynamics
MaxEnt algorithm information theory statistical mechanics Hamiltonian dynamics
2010/11/24
MaxEnt inference algorithm from the information theory is relevant for the time evolution of macroscopic systems which represents a problem of incomplete information. Two different approaches using Ma...
Time evolution of Wigner functions governed by bipartite Hamiltonian system with kinetic coupling

2010/6/30
For the bipartite Hamiltonian system with kinetic coupling, we derive time evolution equation of Wigner functions by virtue of the bipartite entangled state representation and entangled Wigner operato...
