We study a system of ultra-cold atoms possessing long range interaction (e.g. dipole-dipole interaction)in a one dimensional optical lattice in the presence of a confining harmonic trap. We have shown...

The density of states near zero energy in a graphene due to strong point defects with random
positions are computed. Instead of focusing on density of states directly, we analyze eigenfunctions of in...
