Three-Point Functions at Finite Temperature
نویسنده
چکیده
We study 3-point functions at finite temperature in the closed time path formalism. We give a general decomposition of the eight component tensor in terms of seven vertex functions. We derive a spectral representation for these seven functions in terms of two independent real spectral functions. We derive relationships between the seven functions and obtain a representation of the vertex tensor that greatly simplifies calculations in real time.

Three Point Functions at Finite Temperature
We consider the calculations of three-point functions at nite temperature as they are usually performed in the literature. We show that as normally used, the Imaginary-Time and the Real Time nite temperature formalisms calculate expectation values of retarded and time ordered three point functions respectively. We also present a relation between these quantities that shows that they are not gen...

In this paper, the conjugate gradient method coupled with adjoint problem is used in order to solve the inverse heat conduction problem and estimation of the strength of the time- dependent heat source using the temperature distribution at a point in a three layer system. Also, the effect of noisy data on final solution is studied. The numerical solution of the governing equations is obtained b...

Effect of time dependent normal transpiration on the problem of unsteady viscous flow and heat transfer in the vicinity of an axisymmetric stagnation point of an infinite circular cylinder moving simultaneously with time-depended angular and axial velocities and with time-dependent wall temperature or wall heat flux are investigated. The impinging free stream is steady with a strain rate . A re...
متن کاملN-point Functions in Imaginary-and Real-time Finite-temperature Formalisms
It is proved that calculations of three-point diagrams using the Real-Time Formalism of nite temperature eld theory produce the time-ordered Green functions while the Imaginary-Time Formalism calculate retarded and advanced Green functions. A non-trivial relation between these Green functions is found. Similarly, a spectral representation for the real-time three-point function is found. The hig...
متن کاملn-point functions at finite temperature
We study n-point functions at finite temperature in the closed time path formalism. With the help of two basic column vectors and their dual partners we derive a compact decomposition of the time-ordered n-point functions with 2 components in terms of 2n−1 − 1 independent retarded/advanced n-point functions. This representation greatly simplifies calculations in the real-time formalism. PACS nu...
