Constrained instantons and kink-antikink collisions

C. Adam, A. García Martín-Caro, M. Huidobro +3

We show that constrained instantons, combined with the Relativistic Moduli Space approach, can accurately describe kink-antikink collisions in the model.

Quiver diagonalization and open BPS states

Jakub Jankowski, Piotr Kucharski, Hélder Larraguível +2

We show that motivic Donaldson-Thomas invariants of a~symmetric quiver , captured by the generating function , can be encoded in another quiver of (almost al…

Fermionic spectral walls in kink collisions

João G. F. Campos, Azadeh Mohammadi, Jose M. Queiruga +2

We show that a spectral wall, i.e., an obstacle in the dynamics of a bosonic soliton, which arises due to the transition of a normal mode into the continuum spectrum, exists after…

Moduli space with a boundary

C. Adam, K. Oles, T. Romanczukiewicz +1

We find that for various solitonic processes the corresponding canonical moduli space can have a boundary which is accessible in a finite time evolution. We show that such a bounda…

Multikink scattering in the model revisited

C. Adam, P. Dorey, A. Garcia Martin-Caro +5

Antikink-kink ( ) collisions in the model exhibit resonant scattering although the kinks do not support any bound states to which energy could b…

OPE coefficients and the mass-gap from the integrable scattering description of 2D CFT's

Zoltan Bajnok, Romuald A. Janik

Many two-dimensional conformal field theories have an alternative integrable scattering description, which reproduces their spectrum of conformal weights. Taking as an example the…
