Dissipation and the Bulk Viscosity in 1D odd-wave Fermi gases

One-dimensional Fermi gases at low energy are often described by the Luttinger liquid model. To investigate dissipative effects, it is necessary to include non-linear terms whose form depend on the microscopic details of the system. For example, in the investigation of the bulk viscosity of 1D Fermi gases with even parity interactions, three-body effects are required to generate a finite bulk viscosity. In this talk we address the corresponding question for a non-relativistic spin polarized Fermi gas with odd parity interactions and evaluate the bulk viscosity explicitly. We find results consistent with non-relativistic conformal symmetry, and the bulk viscosity is due to two-body interactions beyond the Luttinger liquid model.
