A simple quantum dot: numerical and variational solutions
Connor Walsh, Ian MacPherson, Davidson Joseph +4
We describe a simple quantum dot that consists of two crossed two-dimensional troughs. As such there is no potential well; nonetheless, this geometry gives rise to a bound state, c…

Parapositronium decay into three photons and implications for the neutral pion
Andrzej Czarnecki, Divyesh Dagia, Ting Gao +1
We complete the determination of the parapositronium decay into three photons by evaluating amplitudes mediated by the boson. We show that, contrary to the expectation that the…
