Criticality in 1-dimensional field theories with mesoscopic, infinite range interactions
Kurt Langfeld, Amanda Turner
This research investigates a novel class of one-dimensional theories characterised by a distinctly defined infinite interaction range. We propose that such theories emerge naturall…
Reduced critical slowing down for statistical physics simulations
Kurt Langfeld, Pavel Buividovich, P. E. L Rakow +1
Wang-Landau simulations offer the possibility to integrate explicitly over a collective coordinate and stochastically over the remainder of configuration space. We propose to choos…
Dynamics of epidemic diseases without guaranteed immunity
Kurt Langfeld
The global SARS-CoV-2 pandemic suggests a novel type of disease spread dynamics. WHO states that there is currently no evidence that people who have recovered from COVID-19 and hav…
A density of states approach to the hexagonal Hubbard model at finite density
Michael Körner, Kurt Langfeld, Dominik Smith +1
We apply the Linear Logarithmic Relaxation (LLR) method, which generalizes the Wang-Landau algorithm to quantum systems with continuous degrees of freedom, to the fermionic Hubbard…
String-like theory as solution to the sign problem of a finite density gauge theory
Kurt Langfeld
Z3 gauge theory with dynamical (bosonic) matter is studied in 4 dimensions with a finite chemical potential. This theory could be viewed as an effective theory describing the centr…
Controlling the Sign Problem in Finite Density Quantum Field Theory
Nicolas Garron, Kurt Langfeld
Quantum field theories at finite matter densities generically possess a partition function that is exponentially suppressed with the volume compared to that of the phase quenched a…
