چکیده

We present a new approximation technique for quantum field theory. The standard one-loop result is used as a seed for a recursive formula that gives a sequence of improved Gaussian approximations for the generating functional. In a different setting, the basic idea of this recursive scheme is used in the second part of the paper to substantialy speed up the standard Monte Carlo algorithm. http://www.phy.bg.ac.yu/ctp/pft/a balaz/ http://www.phy.bg.ac.yu/ctp/cmt/a belic/ http://www.phy.bg.ac.yu/ctp/pft/a bogojevic/

Improved Gaussian Approximation

In a recently developed approximation technique [1] for quantum field theory the standard one-loop result is used as a seed for a recursive formula that gives a sequence of improved Gaussian approximations for the generating functional. In this paper we work with the generic φ3+φ4 model in d = 0 dimensions. We compare the first, and simplest, approximation in the above sequence with the one-loo...

Bit Error Performance for Asynchronous Ds Cdma Systems Over Multipath Rayleigh Fading Channels (RESEARCH NOTE)

In recent years, there has been considerable interest in the use of CDMA in mobile communications. Bit error rate is one of the most important parameters in the evaluation of CDMA systems. In this paper, we develop a technique to find an accurate approximation to the probability of bit error for asynchronous direct–sequence code division multiple–access (DS/CDMA) systems by modeling the multipl...

Generalized Hartree Method: A Novel Non-perturbative Approximation Scheme for Interacting Quantum systems

A self-consistent , non-perturbative scheme of approximation is proposed for arbitrary interacting quantum systems by generalization of the Hartree method.The scheme consists in approximating the original interaction term λHI by a suitable ’potential’ λV (φ) which satisfies the following two requirements: (i) the ’Hartree Hamiltonian’ Ho generated by V (φ) is exactly solvable i.e, the eigen sta...
