Dear Users, I would like to define three different J values for nearest neighbour (nn) next nearest neighbour (nnn) next to next nearest neighbour (nnnn) for honeycomb lattice. If I define J0, J1, J2 to the existing honeycomb lattice model (which is available in source files), is these are nothing but J values for nearest neighbour (nn) next nearest neighbour (nnn) next to next nearest neighbour (nnnn) for honeycomb lattice?. In other way, J0, J1, J2...... are they represent the nearest neighbour J values?? I did not got any information how J0, J1, J2..... will be considered in exiting lattices Please clarify Thank you Dr. Bheema Lingam Chittari Post Doctoral Researcher, Room No:14-115, Department of Physics, University of Seoul, 163 Seoulsiripdae-ro, Dongdumen-gu, Seoul, South Korea
