Topological Classification of One-Dimensional Chiral Symmetric Interfaces
Harry MullineauxSanders, Bernd Braunecker
We address the topological classification of one-dimensional chiral symmetric interfaces embedded into a two-dimensional substrate. A proof of the validity of a topological classif…

Exact results, transient generalized Gibbs ensembles, and analytic approximations for spacetime propagators of massive, real scalar fields in one spatial dimension
Tobias Boorman, Bernd Braunecker
The massive, real scalar field described by the Klein-Gordon equation in one spatial dimension is the most elementary example of a bosonic quantum field theory. It has been investi…

Observable-enriched entanglement
Joe H. Winter, Reyhan Ay, Bernd Braunecker +1
We introduce methods of characterizing entanglement, in which entanglement measures are enriched by the matrix representations of operators for observables. These observable operat…
