</span><span class="Apple-style-span" style="font-family: Helvetica; font-size: medium; ">These parameters in my hamiltonian are complex. Is it correct? In PRB 56, 12847 Marzari and Vanderbilt conjecture that optimally localized Wannier functions are alway real then I suppose that the hopping parameter must be real.</span><span class="Apple-style-span" style="font-family: Helvetica; font-size: medium; "> </span><span class="Apple-style-span" style="font-family: Helvetica; font-size: medium; "> </span><span class="Apple-style-span" style="font-family: Helvetica; font-size: medium; "><br>
