*Title: *An effective description of Ramsey tunnel-coupled 1D Bose gases
via the Pokrovsky-Talapov model
*Abstract: *The high flexibility of ultracold atoms allows for the design,
control and thorough investigation of quantum matter. In this work we
consider two one-dimensional Ramsey tunnel-coupled Bose gases and elaborate
on its relation to the Prokrovsky-Talapov model. Further, we study the
ground state with variational wave-functions and explore the experimental
relevant finite system size effects. Finally, we discuss possible quench
protocols in order to study the non-equilibrium evolution of the
Pokrovsky-Talapov model and predict experimental relevant quantities such
as the phase and the density.
