Wave-function renormalization for the Coulomb-gas in Wegner-Houghton's RG method

I. Nandori, J. Polonyi, K. Sailer

The RG flow for the sine-Gordon model is determined by means of the method of Wegner and Houghton in next-to-leading order of the derivative expansion. For small values of the fuga…

Shell model study of the isobaric chains A=50, A=51 and A=52

A. Poves, J. Sanchez-Solano, E. Caurier +1

Shell model calculations in the full pf-shell are carried out for the A=50, 51 and 52 isobars. The most frequently used effective interactions for the pf-shell, KB3 and FPD6 are re…

Shell model studies of neutron rich nuclei

E. Caurier, F. Nowacki, A. Poves

We discuss the present status of the description of the structure of the very neutron rich nuclei, in the framework of modern large scale shell model calculations. Particular atten…

Renormalization of composite operators

J. Polonyi, K. Sailer

The blocked composite operators are defined in the one-component Euclidean scalar field theory, and shown to generate a linear transformation of the operators, the operator mixing.…

Chaos and isospin symmetry breaking in rotational nuclei

J. A. Sheikh, A. T. Kruppa, N. Rowley

For nuclei with N = Z, the isospin degree of freedom is important and, for deformed systems, rotational bands of different isospin may be expected at low excitation energies. We ha…

Quantization of Lie bialgebras and shuffle algebras of Lie algebras

B. Enriquez

To any field K of characteristic 0, we associate a set Sha(K). Elements of Sha(K) are equivalence classes of families of Lie polynomials subject to associativity relations. We cons…

Invariants of Knots and 3-manifolds from Quantum Groupoids

Dmitri Nikshych, Vladimir Turaev, Leonid Vainerman

We use categories of representations of finite dimensional quantum groupoids (weak Hopf algebras) to construct ribbon and modular categories that give rise to invariants of knots a…

Sideward flow of K+ mesons in Ru+Ru and Ni+Ni reactions near threshold

P. Crochet, N. Herrmann, K. Wisniewski +2

Experimental data on K+ meson and proton sideward flow measured with the FOPI detector at SIS/GSI in the reactions Ru+Ru at 1.69 AGeV and Ni+Ni at 1.93 AGeV are presented. The K+ s…

Fate of the classical false vacuum

Sz. Borsanyi, A. Patkos, J. Polonyi +1

Thermalisation of configurations with initial white noise power spectrum is studied in numerical simulations of a classical one-component $Φ^{4}$ theory in 2+1 dimensions, coupled to…

The pion charge radius from charged pion electroproduction

Véronique Bernard, Norbert Kaiser, Ulf-G. Meißner

We analyze a low-energy theorem of threshold pion electroproduction which allows one to determine the charge radius of the pion. We show that at the same order where the radius app…

Rectangular Scott-type Permanents

Guo-Niu Han, Christian Krattenthaler

Let $x_{1}, x_{2}, ..., x_{n}$ be the zeroes of a polynomial P(x) of degree n and $y_{1}, y_{2}, ..., y_{m}$ be the zeroes of another polynomial Q(y) of degree m. Our object of study is the permanen…

The geometry of the Barbour-Bertotti theories I. The reduction process

László Á Gergely

The dynamics of $N \geq 3$ interacting particles is investigated in the non-relativistic context of the Barbour-Bertotti theories. The reduction process on this constrained system y…

Second post-Newtonian radiative evolution of the relative orientations of angular momenta in spinning compact binaries

László Á. Gergely

The radiative evolution of the relative orientations of the spin and orbital angular momentum vectors $S_{1}, S_{2}$ and $L$ , characterizing a binary syst…

Non perturbative renormalization group potentials and quintessence

Vincenzo Branchina

New solutions to the non perturbative renormalization group equation for the effective action of a scalar field theory in the Local Potential Approximation having the exponential f…

Dynamical Origin of Decoherence in Clasically Chaotic Systems

F. M. Cucchietti, H. M. Pastawski, R. Jalabert

The decay of the overlap between a wave packet evolved with a Hamiltonian H and the same state evolved with H}+ $Σ$ serves as a measure of the decoherence time $τ_{ϕ}$ . Recent experim…

Light-particle emission from the fissioning nuclei 126Ba, 188Pt and (266,272,278)/110: theoretical predictions and experimental results

K. Pomorski, B. Nerlo-Pomorska, A. Surowiec +9

We present a comparison of our model treating fission dynamics in conjunction with light-particle (n, p, alpha) evaporation with the available experimental data for the nuclei 126B…
