Bloch-wall phase transition in the spherical model
The temperature-induced second-order phase transition from Bloch to linear (Ising-like) domain walls in uniaxial ferromagnets is investigated for the model of D-component classical spin vectors in the limit D → ∞. This exactly soluble model is equivalent to the standard spherical model in the homogeneous case, but deviates from it and is free from unphysical behavior in a general inhomogeneous ...
متن کاملBerry phase for a particle in an infinite spherical potential well with moving wall
In this paper we calculate the Berry phase for a wave function of a particle in an infinite spherical potential well with adiabatically varying. In order to do this, we need the solutions of the corresponding Schrödinger equation with a time dependent Hamiltonian. Here, we obtain these solutions for the first time. In addition, we calculate the Berry phase in one dimensional case for an infinit...
متن کاملTopology, phase transitions, and the spherical model.
The topological hypothesis states that phase transitions should be related to changes in the topology of configuration space. The necessity of such changes has already been demonstrated. We characterize exactly the topology of the configuration space of the short range Berlin-Kac spherical model, for spins lying in hypercubic lattices of dimension d. We find a continuum of changes in the topolo...
متن کاملFirst-order phase transition of the tethered membrane model on spherical surfaces
We found that three types of tethered surface model undergo a first-order phase transition between the smooth and the crumpled phase. The first and the third are discrete models of Helfrich, Polyakov, and Kleinert, and the second is that of Nambu and Goto. These are curvature models for biological membranes including artificial vesicles. The results obtained in this paper indicate that the firs...
متن کاملPhase Transition in the Ising Model
These are lecture notes for a talk based on “An Introduction to the Ising Model” by Barry Cipra. Available at http://www.maa.org/programs/ maa-awards/writing-awards/an-introduction-to-the-ising-model. Some of the notation has been changed from the paper for clarity.
