Regularized Quantum Master Equation in the Wilsonian Renormalization Group
Using the Pauli-Villars regularization, we make a perturbative analysis of the quantum master equation (QME), Σ = 0, for the Wilsonian effective action. It is found that the QME for the UV action determines whether exact gauge symmetry is realized along the renormalization group (RG) flow. The basic task of solving the QME can be reduced to compute the Troost-van Niuwenhuizen-Van Proyen jacobia...
متن کاملBRS Symmetry, the Quantum Master Equation, and the Wilsonian Renormalization Group
Recently we made a proposal for realization of an effective BRS symmetry along the Wilsonian renormalization group flow. In this paper we show that the idea can be naturally extended for the most general gauge theories. Extensive use of the antifield formalism is made to reveal some remarkable structure of the effective BRS symmetry. The average action defined with a continuum analog of the blo...
متن کاملAxial Anomaly from the BPHZ regularized BV master equation
A BPHZ renormalized form for the master equation of the field antifield (or BV) quantization has recently been proposed by De Jonghe, Paris and Troost. This framework was shown to be very powerful in calculating gauge anomalies. We show here that this equation can also be applied in order to calculate a global anomaly (anomalous divergence of a classically conserved Noether current), considerin...
متن کاملOn the quantum master equation for fermions
A quantum master equation is obtained for identical fermions by including a relaxation term in addition to the mean-field Hamiltonian. [Huang C F and Huang K N 2004 Chinese J. Phys. 42 221; Gebauer R and Car R 2004 Phys. Rev. B 7
متن کاملDecoherence and quantum-classical master equation dynamics.
The conditions under which quantum-classical Liouville dynamics may be reduced to a master equation are investigated. Systems that can be partitioned into a quantum-classical subsystem interacting with a classical bath are considered. Starting with an exact non-Markovian equation for the diagonal elements of the density matrix, an evolution equation for the subsystem density matrix is derived. ...
