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 ...
Quantum Filtering for Systems Driven by Fields in Single Photon States and Superposition of Coherent States using Non-Markovian Embeddings
quantum filtering continuous-mode single photon states continuous-mode superpositions of coherent states quantum stochastic processes
2011/10/8
Abstract: The purpose of this paper is to determine quantum master and filter equations for systems coupled to fields in certain non-classical continuous-mode states. Specifically, we consider two typ...
From Low-Distortion Norm Embeddings to Explicit Uncertainty Relations and Efficient Information Locking
uncertainty relations information locking low-distortion norm embedding
2010/11/5
We exploit a connection between uncertainty relations and low-distortion embeddings of L2 into L1, which allows us to adapt an explicit low-distortion embedding to obtain efficient entropic uncertaint...
Coarse-graining of inhomogeneous dust flow in General Relativity via isometric embeddings
inhomogeneous dust flow isometric embeddings
2010/3/17
We present a new approach to coarse-graining of variables describing dust flow in GR. It is based on assigning quasi-local shear, twist and expansion to 2-dimensional surfaces with the help of isometr...
