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…
The Antiferromagnetic Character of the Quantum Phase Transition in the Hubbard Model on the Honeycomb Lattice
Johann Ostmeyer, Evan Berkowitz, Stefan Krieg +3
We provide a unified, comprehensive treatment of all operators that contribute to the anti-ferromagnetic, ferromagnetic, and charge-density-wave structure factors and order paramet…
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…
Avoiding Ergodicity Problems in Lattice Discretizations of the Hubbard Model
Jan-Lukas Wynen, Evan Berkowitz, Christopher Körber +2
The Hubbard model arises naturally when electron-electron interactions are added to the tight-binding descriptions of many condensed matter systems. For instance, the two-dimension…
