The soliton nature of the super-Klein tunneling effect
Francisco Correa, Luis Inzunza, Olaf Lechtenfeld
We establish a relationship between the Davey--Stewartson II (DS II) integrable system in dimensions and quasi-exactly solvable planar interacting Dirac Hamiltonians that…

Quasi-isospectral higher-order Hamiltonians via a reversed Lax pair construction
Francisco Correa, Andreas Fring
We present a novel approach for constructing quasi-isospectral higher-order Hamiltonians from time-independent Lax pairs by reversing the conventional interpretation of the Lax pai…

Integrable black hole dynamics in the asymptotic structure of AdS
Marcela Cárdenas, Francisco Correa, Miguel Pino
This work deepens the study of integrable asymptotic symmetries for AdS. They are given by an infinite set of integrable nonlinear equations known as the Ablowitz-Kaup-Newell…
