The renormalization group theory of second‐order phase transitions is described in a form suitable for presentation as part of an undergraduate statistical physics course. 
A New Approach to Real Space Renormalization Group Treatment of Ising Model for Square and Simple Cubic Lattice
Real Space Renormalization Group (RSRG) treatment of Ising model for square and simple cubic lattice is investigated and critical coupling strengths of these lattices are obtained. The mathematical...
Renormalization group solution of the harmonic oscillator
An alternative calculation of the path integral for the harmonic oscillator is carried out as recommended in the textbook of Feynman and Hibbs. A surprising generalization of the angle-doublingExpand
Intuitive understanding of T???0 behavior of 2d spin glasses via renormalization group analysis

Renormalization group theory in solution thermodynamics
Abstract Renormalization group theory is a powerful technique from condensed matter physics that has many potential applications in applied molecular thermodynamics, although it has not yet beenExpand
Renormalization of one-dimensional avalanche models
We investigate a renormalization group (RG) scheme for avalanche automata introduced recently by Pietroneroet al. to explain universality in self-organized criticality models. Using a modifiedExpand
Effective interactions and the hydrogen atom
The technique of effective interactions, which has become commonplace in contemporary particle/nuclear physics, is used to analyze the structure of hydrogen atom energy levels.
Wilsonian Renormalization Group
In this central chapter of Part I we introduce the basic concepts of the RG method invented by Wilson and coauthors in a series of pioneering articles (Wilson 1969, 1971b,c, 1972, Wilson and FisherExpand
The universal Hamiltonian of the exchange interaction for the system of particles with an arbitrary spin j
On the basis of the arrangement symmetry for the system of identical particles the universal Hamiltonian of the exchange interaction in the spin representation is developed. For the case of spin-1/2Expand
Critical point phenomena, heat capacities and the renormalization group theory of fluctuations
In the normal study of matter, the ordered state is considered first, followed by the addition of minor disorder or fluctuations, for instance, studying crystalline solids with some quasiparticleExpand
A simpler derivation of Feigenbaum’s renormalization group equation for the period-doubling bifurcation sequence
One interesting and important property of nonlinear dynamical systems is that they can exhibit universality—behavior that is quantitatively identical for a broad class of systems. The first and mostExpand
