• closedAccess   On the structure and convergence of the symmetric Zassenhaus formula 

      Arnal, A.; Casas, Fernando; Chiralt, Cristina Elsevier (2017-08)
      We propose and analyze a symmetric version of the Zassenhaus formula for disentangling the exponential of two non-commuting operators. A recursive procedure for generating the expansion up to any order is presented which ...
