Field Formulation of Many-Body Quantum Physics {ffmbqp
... A piece of matter composed of a large number of microscopic particles is called a many-body system. The microscopic particles may either be all identical or of different species. Examples are crystal lattices, liquids, and gases, all of these being aggregates of molecules and atoms. Molecules are co ...

Correlation Length versus Gap in Frustration-Free
... holds with ξ ¼ Oð1=ϵÞ for any ground state jψi [6], where G is the projector onto the ground space. An overview of these results and the proof techniques used to obtain them is given in Ref. [7]. Here we specialize to frustration-free geometrically local Hamiltonians. Frustration-freeness means that ...
