Localized states of the non-Hermitian Schr{ö}dinger equation with a complex $1/r^2$ potential: from Efimov states to bipolarons

Kyoka Tsunoda, Kazuki Yamamoto, Shimpei Endo

We study the non-Hermitian Schrödinger equation with a complex $1/r^2$ potential, which bridges Hermitian few-body and non-Hermitian many-body physics: a real attractive potentia…
