In particular, it is pointed out that the shear viscosity of lattice fluids is the sum of two contributions, one due to the usual interactions between particles (collision viscosity) and the other due to the interaction with the discrete lattice (propagation viscosity). Since the latter is negative, the sum may turn out to be orders of magnitude smaller than each of the two contributions separately, thus providing a mechanism to access SIF regimes at ordinary values of the collisional viscosity. This concept, as applied to quantum superfluids in one-dimensional optical lattices, is shown to reproduce shear viscosities consistent with the AdS-CFT holographic bound on the viscosity\/entropy ratio. This shows that lattice kinetic theory continues to hold for strongly coupled hydrodynamic regimes where continuum kinetic theory may no longer be applicable.<\/jats:p>","DOI":"10.3390\/e17096169","type":"journal-article","created":{"date-parts":[[2015,9,3]],"date-time":"2015-09-03T10:57:07Z","timestamp":1441277827000},"page":"6169-6178","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Short-Lived Lattice Quasiparticles for Strongly Interacting Fluids"],"prefix":"10.3390","volume":"17","author":[{"given":"Miller","family":"Jimenez","sequence":"first","affiliation":[{"name":"ETH Z\u00fcrich, Computational Physics for Engineering Materials, Institute for Building Materials,Wolfgang-Pauli-Strasse 27, HIT, CH-8093 Z\u00fcrich, Switzerland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sauro","family":"Succi","sequence":"additional","affiliation":[{"name":"Istituto per le Applicazioni del Calcolo C.N.R., Via dei Taurini 19, 00185 Rome, Italy"},{"name":"Institute for Applied Computational Science, Harvard University, Oxford Street, 52, Cambridge, 02138 MA, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2015,9,3]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Sachdev, S.
