Unitary Matrix Models and Phase Transition

چکیده

We study the unitary matrix model with a topological term. We call the topological term the theta term. In the symmetric model there is the phase transition at λc = 2. If the Wilson term is larger than the theta term, there is the phase transition at the same λc. On the other hand, if the theta term is larger than the Wilson term, there is no phase transition.

Unitary Matrix Models with a topological term and discrete time Toda equation

We study the full unitary matrix models. Introducing a new term l logU , l plays the role of the discrete time. On the other hand, the full unitary matrix model contains a topological term. In the continuous limit it gives rise to a phase transition at θ = π. The ground state is characterize by the discrete time l. The discrete time l plays like the instanton number.

Multicritical Matrix Models and the Chiral Phase Transition CPT

Universality of multicritical unitary matrix models is shown and a new scaling behavior is found in the microscopic region of the spectrum, which may be relevant for the low energy spectrum of the Dirac operator at the chiral phase transition.

رهیافت معادلات جریان در مدل آیزینگ کوانتمی یک بعدی

One dimensional quantum Ising model with nearest neighbor interaction in transverse magnetic field is one of the simplest spin models which undergo quantum phase transition. This model has been precisely solved using different methods. In this paper, we solve this model in uniform magnetic field -Jgσxn precisely using a new method called Continuous Unitary Transformations (CUT) or flow equation...

Transition and Damping of Collective Modes in a Trapped Fermi Gas between BCS and Unitary Limits near the Phase Transition

We investigate the transition and damping of low-energy collective modes in a trapped unitary Fermi gas by solving the Boltzmann-Vlasov kinetic equation in a scaled form, which is combined with both the T-matrix fluctuation theory in normal phase and the mean-field theory in order phase. In order to connect the microscopic and kinetic descriptions of many-body Feshbach scattering, we adopt a ph...

J an 2 00 7 Quantum Equivalence of NC and YM Gauge Theories in 2 D and Matrix Theory

We construct noncommutative U (1) gauge theory on the fuzzy sphere S 2 N as a unitary 2N × 2N matrix model. In the quantum theory the model is equivalent to a nonabelian U (N) Yang-Mills theory on a 2 dimensional lattice with 2 plaquettes. This equivalence holds in the " fuzzy sphere " phase where we observe a 3rd order phase transition between weak-coupling and strong-coupling phases of the ga...
