Abstract
We present a Bethe-ansatz-solvable dissipative model of one-dimensional hard-core anyons under dephasing, where the particles obey fractional statistics. We establish an exact mapping between the Liouvillian and a non-Hermitian Hubbard model with special twisted boundary conditions. With the help of string hypothesis, we rigorously calculate the finite-size corrections and the Liouvillian gap in terms of the statistical parameter, total particle number, lattice size, and dissipation strength. The statistical parameter breaks the -pairing symmetry of the system, partially lifts out the degeneracy of the spectrum, and contributes to the Liouvillian gap in finite-size corrections. We also derive the general form of the equation of motion for expectation values of the -point correlator of hard-core anyons and present a proposal for experimentally measuring the correlation function. Our results shed light on the Liouvillians of exactly solvable dissipative models of anyonic particles that obey the fractional statistics.
