Three- and four-boson systems expanded around the unitarity limit: Application to He
Feng Wu, Xincheng Lin, Ubirajara van Kolck +1
The three- and four-boson systems with a large scattering length and a short effective range in the two-body sector are studied in the framework of Short-Range Effective Field Theo…
Coulomb Effects and Wigner-SU(4) Symmetry in He-3 Charge and Magnetic Properties
Xincheng Lin
This work studies the non-perturbative Coulomb corrections to the He-3 binding energy, magnetic moment, and charge and magnetic radii in leading-order (LO) Pionless Effective Field…
The Three-Body Limit Cycle: Universal Form for General Regulators
Langxuan Chen, Feng Wu, Xincheng Lin +3
The Efimov effect, a remarkable realization of discrete scale invariance, emerges in the three-body problem with short-range interactions and is understood as a renormalization gro…
Two-Body Triton Photodisintegration and Wigner-SU(4) Symmetry
Xincheng Lin, Jared Vanasse
We calculate the two-body triton photodisintegration cross section as a function of photon energy to next-to-next-to leading order (NNLO) in pionless effective field theory (EFT($Ï…
