Correlation Decay in Fermionic Lattice Systems with Power-Law Interactions at Nonzero Temperature
Author(s): Senaida Hernández-Santana, Christian Gogolin, J. Ignacio Cirac, and Antonio Acín
We study correlations in fermionic lattice systems with long-range interactions in thermal equilibrium. We prove a bound on the correlation decay between anticommuting operators and generalize a long-range Lieb-Robinson-type bound. Our results show that in these systems of spatial dimension $D$ with...
