Henrique N. Sá Earp, Jiannis K. Pachos · Journal of Mathematical Physics · 2005
We present an explicit numerical method to obtain the Cartan-Khaneja-Glaser decomposition of a general element G∊SU(2N) in terms of its “Cartan” and “non-Cartan” components. This effectively factors G in terms of group elements that belong in SU(2n) with n
