The Quantum-Statistical Condensate of One-Dimensional Anyons — •Thore Posske¹, Björn Trauzettel², and Michael Thorwart¹ — ¹I.

We develop an exact many-body formalism for one-dimensional anyons, the hybrid particles between bosons and fermions. Besides providing characteristic observables, we reveal the quantum-statistical condensate. This genuine many-body condensate is created purely by quantum-statistical attraction. It is potentially more stable than a Bose-Einstein condensate and carries a rich structure of degenerate internal excitations. Parallels to the Lieb-Liniger model of interacting bosons are discussed.
