檢視 $spuriouslimit 的原始碼

$spuriouslimit defines the criteria for eigen solver to remove the spurious mode. When we solve eigen function of electron and holes, we will define a computing window. At the boundary, we force the wavefunction to be zero. However, the accurate condition is that the wave does not exist in the computing boundary. Otherwise, these modes might be spurious except that the boundary is a real hard boundary where wavefunction is zero at the boundary. Spuriouslimit defines the value where the program will detect the value of wave function near the boundary. If the value is too large it will remove these spurious modes. The default number is 10.0. If you want to get more spurious modes you can adjust the value to 100.0 or 1000.0
