Title: “Zeros of the partition function and their algorithmic application”
Venue&Time: Gray Room 1 / 11:30
Abstract: “At high temperatures quantum systems generally lose
long-range order. We would expect that this makes them easier to
simulate. One way to understand this is through the analytic
properties of the partition function. Viewing Z(beta) = tr e^{-beta
H} as a function of a complex beta, its zeros turn out to tell us both
about phase transitions and about classical algorithms for estimating
Z(beta).”
