Abstract
Historically the presence of dissipation in quantum systems was viewed as parasitic, as it would destroy quantum coherences. This picture has become more and more challenged, as dissipation can be used as a resource to produce strongly correlated quantum states. One primary example is the 1D Bose gas, where fermionization can be achieved not only by strong elastic two-body interactions, but by strong two-body losses. In this talk we explore the consequences of this dissipation induced fermionization by examining the collective modes of a harmonically trapped 1D Bose gas with strong two-body losses using a dissipative kinetic theory. We find that dissipation induces a new collective mode. We characterize this collective mode, and show that although it has the same frequency as the breathing mode, it is distinct from the closed system dynamics
