Query: K-field kinks in two-dimensional dilaton gravity   In this work, kinks with non-canonical kinetic energy terms are studied in a
type of two-dimensional dilaton gravity model. The linear stability issue is
generally discussed for arbitrary static solutions, and the stability criteria
are obtained. As an explicit example, a model with cuscuton term is studied.
After rewriting the equations of motion into simpler first-order formalism and
choosing a polynomial superpotential, an exact self-gravitating kink solution
is obtained. The impacts of the cuscuton term are discussed.
