Testing the lattice Hamiltonian built from partitionings
Marco Garofalo, Tobias Hartung, Timo Jakobs +5
We test a possible digitization of lattice gauge theories based on partitionings of the sphere . In our construction the link operators are unitary and diagon…
Simple Ways to improve Discrete Time Evolution
Johann Ostmeyer
Suzuki-Trotter decompositions of exponential operators like are required in almost every branch of numerical physics. Often the exponent under consideration has to be sp…
Fermionic Sign Problem Minimization by Constant Path Integral Contour Shifts
Christoph Gäntgen, Evan Berkowitz, Thomas Luu +2
The path integral formulation of quantum mechanical problems including fermions is often affected by a severe numerical sign problem. We show how such a sign problem can be allevia…
Canonical Momenta in Digitized SU(2) Lattice Gauge Theory: Definition and Free Theory
Timo Jakobs, Marco Garofalo, Tobias Hartung +5
Hamiltonian simulations of quantum systems require a finite-dimensional representation of the operators acting on the Hilbert space H. Here we give a prescription for gauge links a…
