Critical point phenomena

Contemporary Physics, 1969
Abstract During the last decade considerable effort has been expended in the study of critical phenomena. These investigations are especially rewarding because they provide important links between several diverse branches of physics. For example, antiferromagnets, pure fluids, binary solutions and alloys all exhibit analogous critical behaviour.

Critical magnetic phenomena

Physics Bulletin, 1978
A variety of crystals with magnetic properties approximating to those of 'ideal' one (Id) and two (2d) dimensional arrays of localised spins, much studied by theoreticians, are now available for experimental study. Many of the ideal systems exhibit no long-range magnetic order at low temperatures, so that short-range effects become important giving ...

Quantum Critical Phenomena

2020
Quantum critical phenomena originate from collective behavior of strongly correlated particles and lie at the heart of universal low-energy properties in many-body systems. The strong correlation between quantum particles is particularly prominent in a low-dimensional system. In the first part of this Chapter, we identify what types of measurements are

Chemical Instabilities as Critical Phenomena

Physical Review A, 1977
Much attention has been given in recent years to universal features characterizing instabilities and transition phenomena in equilibrium and non-equilibrium systems [1]. Laser transitions [2], hydrodynamical instabilities [3], cooperative phenomena in data processing [4] and various examples of chemical and biochemical instabilities [5] are only a few ...

Critical phenomena in atomic physics

Physica E: Low-dimensional Systems and Nanostructures, 2001
Abstract It is shown that the threshold energy e =0 for complete break-up of N charged particles represents a fixed point of the dynamical system. Renormalization theory akin to thermodynamical phase transitions is used to determine the exponent β of the power law for the fragmentation cross section σ ( e )∝ e β near the fixed point. In the
