Quantum scattering by intersecting δ-potential barriers: from Gaudin's kaleidoscope to quantum Galperin billiards

Yi-Cong Yu, Wen-Jie Qiu, Xiaoming Cai

We develop a general framework for the scattering of a plane wave by a class of Gaudin kaleidoscope models: straight $\delta$-potential barriers intersecting at a common point. The proj…
