Researchers have finally resolved a century-old debate over the famous "double slit" experiment, according to new research.

IN an earlier paper1, we have described a new type of interferometer which has been used to measure the angular diameter of radio stars2. In this instrument the signals from two aerials Ax and A2 (Fig ...

多类拓扑半金属在拓扑带交叉处具有相反手性的费米子。拓扑系统中的手性费米子输运通常依赖于强磁场或磁掺杂剂来抑制平凡输运，并造成相反陈数态占据数的不平衡。 研究组利用拓扑带的量子几何特性，通过手性将费米子滤入不同的陈数极化态。这实现了具有相反手性的费米子电流在实空间中分离，通过观察其在无外加磁场条件下的量子干涉，研究组证明了这一点。 由单晶PdGa制成的三臂构型器件表现出量子几何诱导的手性费米子异常速 ...
