This paper is the first in a series that will look at the theory of phase transitions from the perspectives of physics and the philosophy of science. The series will consider a group of related concepts derived from condensed matter and statistical physics. The key technical ideas go under the names of “singularity”, “order parameter”, “mean field theory”, “variational method”, “correlation length”, “universality class”, “scale changes”, and “renormalization”. The first four of these will be… Expand

Phases of Matter and Phase Transitions; From Mean Field Theory to Critical Phenomena
This paper is the second in a series[1] that looks at the theory of the phases of matter from the perspectives of physics and the philosophy of science. The first paper considered the question of howExpand
Relating Theories via Renormalization
Abstract The renormalization method is specifically aimed at connecting theories describing physical processes at different length scales and thereby connecting different theories in the physicalExpand
Real Space Renormalization in Statistical Mechanics
This paper discusses methods for the construction of approximate real space renormalization transformations in statistical mechanics. In particular, it compares two methods of transformation: theExpand
Slippery Wave Functions
Superfluids and superconductors show a very surprising behavior at low temperatures. As their temperature is reduced, materials of both kinds can abruptly fall into a state in which they will supportExpand
Ch-ch-changes philosophical questions raised by phase transitions
Phase transitions are an important instance of putatively emergent behavior. Unlike many things claimed emergent by philosophers (e.g., tables and chairs), the alleged emergence of phase transitionsExpand
Innovations in Statistical Physics
In 1963–71, a group of people, myself included, formulated and perfected a new approach to physics problems, which eventually came to be known under the names of scaling, universality, andExpand
Legendre symmetry and first order phase transitions of homogeneous systems
In this work we give a characterisation of first order phase transitions as equilibrium processes on the thermodynamic phase space for which the Legendre symmetry is broken. Furthermore, we considerExpand
Energy probability distribution zeros: A route to study phase transitions
An iterative method to study the critical behavior of a system based on the partial knowledge of the complex Fisher zeros set of the partition function is presented, which is general with advantages over most conventional techniques since it does not need to identify any order parameter a priori.

Oseen–Frank-type theories of ordered media as the Γ-limit of a non-local mean-field free energy
In this work we recover the Oseen–Frank theory of nematic liquid crystals as a Γ-limit of a particular mean-field free energy as the sample size becomes infinitely large. The Frank constants are notExpand
Why isn't there only physics?
In this thesis, I discuss the relations between descriptions of the world at different levels: through the examination of case studies from condensed matter physics and quantum field theory, I argueExpand


The theory of equilibrium critical phenomena
The theory of critical phenomena in systems at equilibrium is reviewed at an introductory level with special emphasis on the values of the critical point exponents α, β, γ,..., and theirExpand
Static Phenomena Near Critical Points: Theory and Experiment
This paper compares theory and experiment for behavior very near critical points. The primary experimental results are the "critical indices" which describe singularities in various thermodynamicExpand
Phase transitions in small systems: Microcanonical vs. canonical ensembles
We compare phase transition(-like) phenomena in small model systems for both microcanonical and canonical ensembles. The model systems correspond to a few classical (non-quantum) point particlesExpand
The “critical point”
We simulate the ST2 water model for time periods up to 1000 ns, and for four different system sizes, N = 63, 73, 83, and 93. We locate the liquid-liquid phase transition line and its critical pointExpand
Phase Transition in Small Systems
Everybody knows that when a liquid is heated, its temperature increases until the moment when it starts to boil. The increase in temperature then stops, all heat being used to transform the liquidExpand
Peierls Proof of Spontaneous Magnetization in a Two-Dimensional Ising Ferromagnet
HE two-dimensional Ising ferromagnet —we here restrict discussion to the simple square latticehas been the subject of numerous theoretical investigations. ' The thermodynamic properties in theExpand
A Brief History of Our Understanding of BEC: From Bose to Beliaev
We review how our current ideas about BEC developed in the early period 1925-1965, which had the specific goal of understanding superfluid $^4$He. This history is presented by commenting on the keyExpand
The renormalized propagation functions DFC and SFC for photons and electrons, respectively, are investigated for momenta much greater than the mass of the electron. It is found that in this regionExpand
Crystal statistics. I. A two-dimensional model with an order-disorder transition
The partition function of a two-dimensional "ferromagnetic" with scalar "spins" (Ising model) is computed rigorously for the case of vanishing field. The eigenwert problem involved in theExpand
Asymptotics, singularities and the reduction of theories
Publisher Summary This chapter discusses the asymptotics, singularities, and the reduction of theories. The reduction must involve the study of limits—asymptotics. The reduction is obstructed by theExpand
