Sum rules for magnetic moments and polarizabilities in QED and chiral effective-field theory
Anomalous magnetic moment the cross section of discrete integral number arsene wenger reproduction
2014/12/20
We elaborate on a recently proposed extension of the Gerasimov-Drell-Hearn (GDH) sum rule which is achieved by taking derivatives with respect to the anomalous magnetic moment. The new sum rule featur...

Regard Renormalization QED Functor between Categories Mathematical Physics
2011/9/19
Abstract: To unify the quantum electrodynamics (QED) under the first principle which brings the renormalization unartificially, we study Feynman diagrams in QED according to the set theory and the cat...
Finite-temperature nonlinear dynamics in cavity QED: A Thermofield Dynamics Approach
Finite-temperature dynamics Thermofield Dynamics Approach
2011/9/29
Heath-bath effects in the dynamics of atom + cavity system are studied. The temperature effects are explored using thermofield dynamics formalism. It is found that the dynamics of the system is sensit...
Ground states of semi-relativistic Pauli-Fierz and no-pair Hamiltonians in QED at critical Coulomb coupling
Existence of ground states exponential localization no-pair Hamiltonian quantum electrodynamics
2011/7/26
Abstract: We consider the semi-relativistic Pauli-Fierz Hamiltonian and a no-pair model of a hydrogen-like atom interacting with a quantized photon field at the respective critical values of the Coulo...

This week's issue of Nature includes a paper that's remarkable for two reasons: it is about quantum gravity – a topic usually not covered in the journal – and it is written by just one person. Now, af...
Circuit QED with a Nonlinear Resonator : ac-Stark Shift and Dephasing
Circuit QED Nonlinear Resonator ac-Stark Shift and Dephasing
2010/11/9
We have performed spectroscopic measurements of a superconducting qubit dispersively coupled to a nonlinear resonator driven by a pump microwave field. Measurements of the qubit frequency shift provid...
有限温度QED中的轫致辐射修正
QED 有限温度场论 轫致辐射 红外发散
2009/6/9
用有限温度场论方法,通过计算费曼图分析了在QED中由于温度效应导致的新红外发散.结果表明零温场论中的红外发散和由温度效应引起的红外发散可以用描写虚过程的费曼图同时消除.计算了轫致辐射中光子的辐射几率,在Eikonal近似下所得到的结果和半经典近似给出的结果一致.
本文把多时关联格林函数的运动方程转变成等时关联格林函数的运动方程,包括电子和光子的密度矩阵的运动方程以及等时顶点的运动方程,在二体关联截断近似下,给出运动方程,高斯定律及Ward恒等式的明显表达式.
