Worldline approach to few-body physics on the lattice
Hersh Singh
We study the physics of two species of non-relativistic hard-core bosons with attractive or repulsive delta function interactions on a spacetime lattice using the worldline formula…

Large- Relationships Among Two-Derivative Pionless Effective Field Theory Couplings
Matthias R. Schindler, Hersh Singh, Roxanne P. Springer
We analyze two-derivative two-nucleon interactions in a combined pionless effective field theory and large- expansion. At leading order in the large- expansion, relations…
