Emergence More is Different Symmetry Breaking Earman's Principle
2016/6/14
Beginning with Anderson (1972), spontaneous symmetry breaking (SSB) in infinite quantum systems is often put forward as an example of (asymptotic) emergence in physics, since in theory no finite syste...

Emergence Symmetry Breaking Renormalization Group Condensed Matter Explanation
2009/11/18
This paper looks at emergence in physical theories and argues that an appropriate way to understand so-called ``emergent protectorates'' is via the explanatory apparatus of the renormalization group. ...
