    • Solvable self-dual impurity models 

      Adam, Christoph; Oles, K.; Fernández Queiruga, José Manuel; Romanczukiewicz, T.; Wereszczynski, Andrzej (Springer, 2019)
      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 topologically trivial case and for kink (or antikink) ...
    • Spectral walls in soliton collisions 

      Adam, Christoph; Oles, K.; Romanczukiewicz, T.; Wereszczynski, Andrzej (American Physical Society, 2019)
      During defect-antidefect scattering, bound modes frequently disappear into the continuous spectrum before the defects themselves collide. This leads to a structural, nonperturbative change in the spectrum of small excitations. ...
