Consistency of Blocking Transformationsinthe Finite - Temperature Renormalization
The nite-temperature renormalization group is formulated via the Wilson-Kadanoo blocking transformation. Momentum modes and the Matsubara frequencies are coupled by constraints from a smearing function which plays the role of an infrared cutoo regulator. Using the scalar 4 theory as an example, we consider four general types of smearing functions and show that, to zeroth-order in the derivative...
متن کاملDynamical casimir effect at finite temperature
Thermal effects on the creation of particles under the influence of time-dependent boundary conditions are investigated. The dominant temperature correction to the energy radiated by a moving mirror is derived by means of response theory. For a resonantly vibrating cavity the thermal effect on the number of created photons is obtained nonperturbatively. Finite temperatures can enhance the pure ...
متن کاملImproved Holographic Yang-Mills at Finite Temperature: Comparison with Data
The semi-phenomenological improved holographic model for QCD is confronted with data of the pure glue, large-Nc gauge theory. After fitting two phenomenological parameters in the potential, the model can reproduce in detail all thermodynamic functions at finite temperature. It also reproduces in detail all known spin-0 and spin-2 glueball observables at zero temperature and predicts the rest of...
متن کاملQuarkonium at Finite Temperature
There was considerable interest in the properties and the fate of heavy quarkonium states at finite temperature since the famous conjecture by Matsui and Satz [1]. It has been argued that color screening in medium will lead to quarkonium dissociation above deconfinement, which in turn can signal quark gluon plasma formation in heavy ion collisions. The basic assumption behind the conjecture by ...
متن کاملQuarkonium at finite temperature
Lattice QCD studies on charmonium at finite temperature are presented After a discussion about problems for the Maximum Entropy Method applied to finite temperature lattice QCD, I show several results on charmonium spectral functions. The “wave function” of charmonium is also discussed to study the spatial correlation between quark and anti-quark in deconfinement phase.
