Spontaneous Symmetry Breaking in Quantum Systems:Emergence or Reduction?
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...
Philosophical Aspects of Spontaneous Symmetry Breaking
Spontaneous symmetry breaking c-star algebras GNS theorem infinite spin chain algebraic quantum field theory heuristic quantum field theory
2016/5/31
This essay expounds the algebraic framework describing general physical theories, within which the phenomenon of spontaneous symmetry breaking (SSB) makes its appearance in infinite quantum systems. T...
Emergence, Singularities, and Symmetry Breaking
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. ...

2008/4/22
Given its importance in modern physics, philosophers of science have paid surprisingly little attention to the subject of symmetries and invariances, and they have largely neglected the subtopic of sy...
Spontaneous Symmetry Breaking (II): Variations in Complex Models
symmetry spontaneous breaking of symmetry
2008/4/21
This paper, part II of a two-part project, continues to explore the meaning of spontaneous symmetry breaking (SSB) by applying and expanding the general notion we obtained in part I to some more compl...
Spontaneous Symmetry Breaking and Chance

2008/4/21
In this paper I explore the nature of spontaneous symmetry breaking in connection with a cluster of interrelated concepts such as Curie's symmetry principle, chance, and stability.
The Meaning of Spontaneous Symmetry Breaking (I): From a simple classical model

2008/4/21
This paper, part I of a two-part project, aims at answering the simple question 'what is spontaneous symmetry breaking?' by analyzing from a philosophical perspective a simple classical model. Related...
