Hello, In model.xml file, the Boson Hubbard model has the tunneling parameter "t", however in the bondterm "-t#*( bdag(i)b(j)+bdag(j)b(i) )" the parameter is defined as "t#" and its default value is zero. When the tunneling parameter is defined by "t" in python or command line, will it be any difference if I change the default value of "t#" into "t" in model.xml file? Thanks. Xiao Liang
