Recently there has been great interest on tunable lattice which
shows adjustable condensed matter properties. Among those, hexagonal
lattice attracts particular lattice due to its relevance to
relativistic Dirac particle. Here, We introduce a different lattice
which shows interesting topological properties similar to elementary
particles in particle physics. We discuss about interesting aspects
of the new lattice such as Berry phase, quantum Hall effects, and
perfect nesting of its Fermi level.
