Screened perturbation theory at four loops
We study the thermodynamics of massless φ-theory using screened perturbation theory, which is a way to systematically reorganise the perturbative series. The free energy and pressure are calculated through four loops in a double expansion in powers of g and m/T , where m is a thermal mass of order gT . The result is truncated at order g. We find that the convergence properties are significantly...
متن کاملOptimized Perturbation Theory at Finite Temperature
An optimized perturbation theory (OPT) at finite temperature T , which resums higher order terms in the naive perturbation, is developed in O(N) φ theory. It is proved that (i) the renormalization of the ultra-violet divergences can be carried out systematically in any given order of OPT, and (ii) the Nambu-Goldstone theorem is fulfilled for arbitrary N and for any given order of OPT. The metho...
متن کاملCorrelation Energy Estimators based on Møller-Plesset Perturbation Theory
Some methods for the convergence acceleration of the Møller-Plesset perturbation series for the correlation energy are discussed. The order-by-order summation is less effective than the Feenberg series. The latter is obtained by renormalizing the unperturbed Hamilton operator by a constant factor that is optimized for the third order energy. In the fifth order case, the Feenberg series can be i...
متن کاملOn Adiabatic Perturbation Theory for the Energy Eigenvalue Problem
The most customary method to treat quantum-mechanical energy-eigenvalue problems that cannot be solved exactly is the well-known RayleighSchrSdinger perturbation theory. Sometimes, however, it turns out to be more convenient to deal with t ime-independent problems by means of a timedependent formalism, and particularly so when the Hamiltonian of the system can be expressed in terms of quantized...
متن کاملBaryon chiral perturbation theory extended beyond the low-energy region
We consider an extension of the one-nucleon sector of baryon chiral perturbation theory beyond the low-energy region. The applicability of this approach for higher energies is restricted to small scattering angles, i.e. the kinematical region, where the quark structure of hadrons cannot be resolved. The main idea is to re-arrange the low-energy effective Lagrangian according to a new power coun...
