We consider the magnetic- eld dependent spatial magnetization pattern around a general impurity embedded in a Heisenberg antiferromagnet using both an analytical and a numerical spin wave approach. Th...

A fundamental constant in systems of unitary fermions is the so-called Bertsch parameter, the
ratio of the ground state energy for spin paired unitary fermions to that for free fermions at the same d...
