Applications of the worldline Monte Carlo formalism in quantum mechanics
James P. Edwards, Urs Gerber, Christian Schubert +3
In recent years efficient algorithms have been developed for the numerical computation of relativistic single-particle path integrals in quantum field theory. Here, we adapt this "…
Topological Susceptibility of the 2d O(3) Model under Gradient Flow
Wolfgang Bietenholz, Philippe de Forcrand, Urs Gerber +2
The 2d O(3) model is widely used as a toy model for ferromagnetism and for Quantum Chromodynamics. With the latter it shares --- among other basic aspects --- the property that the…
SU(3) Quantum Spin Ladders as a Regularization of the CP(2) Model at Non-Zero Density: From Classical to Quantum Simulation
Wynne Evans, Urs Gerber, Manes Hornung +1
Quantum simulations would be highly desirable in order to investigate the finite density physics of QCD. -d quantum field theories are toy models that sha…
Topological Susceptibility under Gradient Flow
Héctor Mejía-Díaz, Wolfgang Bietenholz, Krzysztof Cichy +4
We study the impact of the Gradient Flow on the topology in various models of lattice field theory. The topological susceptibility is measured directly, and by the slab…
Topology in the 2d Heisenberg Model under Gradient Flow
Ilya O. Sandoval, Wolfgang Bietenholz, Philippe de Forcrand +2
The 2d Heisenberg model --- or 2d O(3) model --- is popular in condensed matter physics, and in particle physics as a toy model for QCD. Along with other analogies, it shares with…
Integral transforms of the quantum mechanical path integral: hit function and path averaged potential
James P. Edwards, Urs Gerber, Christian Schubert +2
We introduce two new integral transforms of the quantum mechanical transition kernel that represent physical information about the path integral. These transforms can be interprete…
