Multi-particle States from the Effective Action for Local Composite Operators: Anharmonic Oscillator

Anna Okopińska

The effective action for the local composite operator $Φ^{2} (x)$ in the scalar quantum field theory with $λ Φ^{4}$ interaction is obtained in the expansion in two-particle-point-irreduc…

Quantum decoherence and an adiabatic process in macroscopic and mesoscopic systems

Stefan V. Mashkevich, Vladimir S. Mashkevich

Quantum decoherence is of primary importance for relaxation to an equilibrium distribution and, accordingly, for equilibrium processes. We demonstrate how coherence breaking implie…

Goldstone Bosons in the Gaussian Approximation

Anna Okopińska

The O(N) symmetric scalar quantum field theory with λΦ^4 interaction is discussed in the Gaussian approximation. It is shown that the Goldstone theorem is fulfilled for arbitrary N…

Leptonic QED Corrections to the process $e p ⟶ e X$ in Jaquet-Blondel variables

Arif Akhundov, Dima Bardin, Lida Kalinovskaya +1

For the study of deep inelastic scattering at HERA, the use of Jaquet-Blondel variables is advantageous in several respects. We calculate the complete leptonic $O (α)$ QED co…

Indeterministic Quantum Gravity II: Refinements and Developments

Vladimir S. Mashkevich

This paper is a continuation of the paper [V.S.Mashkevich, gr-qc/9409010]. Indeterministic quantum gravity is a theory that unifies general relativity and quantum theory involving…

A Numerical Study of Phase Transitions Inside the Pores of Aerogels

Katarina Uzelac, Anwar Hasmy, Rémi Jullien

Phase transitions inside the pores of an aerogel are investigated by modelizing the aerogel structure by diffusion-limited cluster-cluster aggregation on a cubic lattice in a finit…
