Phase transitions and configuration space topology
Equilibrium phase transitions may be defined as nonanalytic points of thermodynamic functions, e. g., of the canonical free energy. Given a certain physical system, it is of interest to understand which properties of the system account for the presence, respectively the absence, of a phase transition, and an understanding of these properties may lead to a deeper understanding of the physical ph...
متن کاملPhase Transitions and Moduli Space Topology
By means of an appropriate re-scaling of the metric in a Lagrangian, we are able to reduce it to a kinetic term only. This form enables us to examine the extended complexified solution set (complex moduli space) of field theories by finding all possible geodesics of this metric. This new geometrical standpoint sheds light on some foundational issues of QFT and brings to the forefront non-pertur...
متن کاملMomentum space topology and quantum phase transitions
Many quantum condensed-matter systems, and probably the quantum vacuum of our Universe, are strongly correlated and strongly interacting fermionic systems, which cannot be treated perturbatively. However, physics which emerges in the low-energy does not depend on the complicated details of the system and is relatively simple. It is determined by the nodes in the fermionic spectrum, which are pr...
متن کاملQuantum phase transitions from topology in momentum space
Many quantum condensed matter systems are strongly correlated and strongly interacting fermionic systems, which cannot be treated perturbatively. However, physics which emerges in the low-energy corner does not depend on the complicated details of the system and is relatively simple. It is determined by the nodes in the fermionic spectrum, which are protected by topology in momentum space (in s...
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...
