Correlating confinement to topological fluctuations near the crossover transition in QCD
Larsen, Rasmus Normann; Sharma, Sayantan; Shuryak, Edward (Peer reviewed; Journal article, 2022)We show the existence of strong (anti)correlations between the topological hot spots and the local values of the trace of the Polyakov loop in 2+1 flavor QCD with physical quark mass, in the vicinity of the crossover ... -
Stable solvers for real-time Complex Langevin
Alvestad, Daniel; Larsen, Rasmus Normann; Rothkopf, Alexander Karl (Peer reviewed; Journal article, 2021-08)This study explores the potential of modern implicit solvers for stochastic partial differential equations in the simulation of real-time complex Langevin dynamics. Not only do these methods offer asymptotic stability, ... -
Static quark-antiquark interactions at nonzero temperature from lattice QCD
Bala, Dibyendu; Kaczmarek, Olaf; Larsen, Rasmus Normann; Mukherjee, Swagato; Parkar, Gaurang Yatin; Petreczky, Peter; Rothkopf, Alexander Karl; Weber, Johannes Heinrich (Peer reviewed; Journal article, 2022)flavor lattice QCD calculations. The study consists of two parts. The first investigates the properties of Wilson line correlators in Coulomb gauge and compares to predictions of hard-thermal loop perturbation theory. As ... -
Towards learning optimized kernels for complex Langevin
Alvestad, Daniel; Larsen, Rasmus Normann; Rothkopf, Alexander Karl (Peer reviewed; Journal article, 2023)We present a novel strategy aimed at restoring correct convergence in complex Langevin simulations. The central idea is to incorporate system-specific prior knowledge into the simulations, in order to circumvent the NP-hard ...
