Wigner SU(4) symmetry, clustering, and the spectrum of C
Shihang Shen, Timo A. Lähde, Dean Lee +1
We present lattice calculations of the low-lying spectrum of C using a simple nucleon-nucleon interaction that is independent of spin and isospin and therefore invariant und…
Impurity Lattice Monte Carlo for Hypernuclei
Dillon Frame, Timo A. Lähde, Dean Lee +1
We consider the problem of including hyperons into the ab initio framework of nuclear lattice effective field theory. In order to avoid large sign oscillations in Monte Carlo s…
Ab initio nuclear thermodynamics
Bing-Nan Lu, Ning Li, Serdar Elhatisari +5
We propose a new Monte Carlo method called the pinhole trace algorithm for {\it ab initio} calculations of the thermodynamics of nuclear systems. For typical simulations of interes…
An update on fine-tunings in the triple-alpha process
Timo A. Lähde, Ulf-G. Meißner, Evgeny Epelbaum
The triple-alpha process, whereby evolved stars create carbon and oxygen, is believed to be fine-tuned to a high degree. Such fine-tuning is suggested by the unusually strong tempe…
The Tjon Band in Nuclear Lattice Effective Field Theory
Nico Klein, Serdar Elhatisari, Timo A. Lähde +2
We explore the lattice spacing dependence in Nuclear Lattice Effective Field Theory for few-body systems up to next-to-next-to leading order in chiral effective field theory includ…
Nuclear Lattice Simulations using Symmetry-Sign Extrapolation
Timo A. Lähde, Thomas Luu, Dean Lee +4
Projection Monte Carlo calculations of lattice Chiral Effective Field Theory suffer from sign oscillations to a varying degree dependent on the number of protons and neutrons. Henc…
