Piercing of domain walls: new mechanism of gravitational radiation

Unknown author (2018)

© 2018, The Author(s). Domain wall (DW) moving in media undergoes the friction force due to particle scattering. However certain particles are not scattered, but perforate the wall. As a result, the wall gets excited in ...
Yang-Baxter deformations beyond coset spaces (a slick way to do TsT)

Unknown author (2018)

© 2018, The Author(s). Yang-Baxter string sigma-models provide a systematic way to deform coset geometries, such as AdSp× Sp, while retaining the σ-model integrability. It has been shown that the Yang-Baxter deformation ...
