Spin in Quantum Field Theory
I introduce spin in field theory by emphasizing the close connection between quantum field theory and quantum mechanics. First, I show that the spin–statistics connection can be derived in quantum mechanics without relativity or field theory. Then, I discuss path integrals for spin without using spinors. Finally, I show how spin can be quantized in a path–integral approach, without introducing ...
متن کاملQuantum field theory of metallic spin glasses.
We introduce an effective field theory for the vicinity of a zero temperature quantum transition between a metallic spin glass (“spin density glass”) and a metallic quantum paramagnet. Following a mean field analysis, we perform a perturbative renormalization-group study and find that the critical properties are dominated by static disorder-induced fluctuations, and that dynamic quantum-mechani...
متن کاملMean field theory of a quantum heisenberg spin glass
A full mean-field solution of a quantum Heisenberg spin-glass model is presented in a large- N limit. A spin-glass transition is found for all values of the spin S. The quantum critical regime associated with the quantum transition at S = 0 and the various regimes in the spin-glass phase at high spin are analyzed. The specific heat is shown to vanish linearly with temperature. In the spin-glass...
متن کاملField theory of spin-singlet quantum Hall states.
We formulate a field theory for the Haldane-Rezayi quantum Hall state and its variants. A new essential ingredient is a class of super Chern-Simons field.
متن کاملQuantum Theory over a Galois Field and Spin Statistics Theorem
In our previous papers it has been shown that quantum theory based on a Galois field (GFQT) possesses a new symmetry between particles and antiparticles, and for massless particles this symmetry (called the AB one) is compatible with all representation operators of the symmetry algebra. In the present paper, it is shown that the AB symmetry is compatible with all representation operators of the...
