Results from the Columbia lattice group study of the QCD finite temperature phase transition with dynamical domain wall fermions on 16 × 4 lattices are presented. These results include an investigation of the U(1) axial symmetry breaking above but close to the transition, the use of zero temperature calculations that set the scale at the transition and preliminary measurements close to the tran...

We study a set of exactly soluble spin models in one and two dimensions for any spin S. Its ground state, the excitation spectrum, quantum phase transition points, as well as dimensional crossover are determined.

We experimentally address the importance of tuning in athermal phase transitions, which are triggered only by a slowly varying external field acting as tuning parameter. Using higher order statistics of fluctuations, a singular critical instability is detected for the first time in spite of an apparent universal self-similar kinetics over a broad range of driving force. The results as well as t...
