#+title: Unitary causal quantum stochastic double products as universal
interactions I

#+date: <2015-04-01>

In
[[http://www.actaphys.uj.edu.pl/findarticle?series=Reg&vol=46&page=1851][this
paper]] with [[http://homepages.lboro.ac.uk/~marh3/][Robin]] we show the
explicit formulae for a family of unitary triangular and rectangular
double product integrals which can be described as second quantisations.
