Non-metric construction of spacetime defects
Jose M. Queiruga
We describe a spacetime endowed with a non-metricity tensor which effectively serves as a model of a spacetime foam. We explore the consequences of the non-metricity in several $f(…

Solvable self-dual impurity models
C. Adam, K. Oles, J. M. Queiruga +2
We find a family of (half) self-dual impurity models such that the self-dual (BPS) sector is exactly solvable, for any spatial distribution of the impurity, both in the topological…

BPS soliton-impurity models and supersymmetry
C. Adam, Jose M. Queiruga, A. Wereszczynski
We find supersymmetric extensions of the half-BPS soliton-impurity models in (1+1) dimensions which preserve half of the supersymmetry. This is related to the fact…
