Schrödinger's problem with cats: measurements and states in the Groupoid Picture of Quantum Mechanics
Florio M. Ciaglia, Fabio Di Cosmo, Alberto Ibort +1
Schrödinger's famous Gedankenexperiment involving a cat is used as a motivation to discuss the evolution of states of the composition of classical and quantum systems in the groupo…
Mathematical Models for Erosion and the Optimal Transportation of Sediment
Björn Birnir, Julie Rowlett
We investigate a mathematical theory for the erosion of sediment which begins with the study of a non-linear, parabolic, weighted 4-Laplace equation on a rectangular domain corresp…
The sound of symmetry
Zhiqin Lu, Julie Rowlett
This note begins with an introduction to the inverse isospectral problem popularized by M. Kac's 1966 article in the American Mathematical Monthly, "Can one hear the shape of a dru…
Differential geometric aspects of parametric estimation theory for states on finite-dimensional C*-algebras
Florio M. Ciaglia, Jürgen Jost, Lorenz Schwachhöfer
A geometrical formulation of estimation theory for finite-dimensional -algebras is presented. This formulation allows to deal with the classical and quantum case in a si…
Geometric characterizations of the cross ratio in a pencil of conics
Alexander Thomas
We give geometric ways to determine the cross ratio of conics in a pencil using elementary projective geometry.
Entanglement Witnesses Based on Symmetric Informationally Complete Measurements
Tao Li, Le-Min Lai, Deng-Feng Liang +2
We study entanglement witness and present a construction of entanglement witnesses in terms of the symmetric informationally complete measurements (SIC-POVM). The capability of our…
