Combinatorics of renormalization as matrix calculus
Abstract We give a simple presentation of the combinatorics of renormalization in perturbative quantum field theory in terms of triangular matrices. The prescription, that may be of calculational value, is derived from first principles, to wit, the...

Is the K-quantum number conserved in the order-to-chaos transition region?
Abstract To study the order-to-chaos transition in nuclei we investigate the validity of the K-quantum number in the excited rapidly rotating 163Er nucleus, analyzing the variance and covariance of the spectrum fluctuations of γ-cascades feeding...

Canonical entropy of three-dimensional BTZ black hole
Abstract Recently, Hawking radiation of the black hole has been studied using the tunnel effect method. It is found that the radiation spectrum of the black hole is not a strictly pure thermal spectrum. How does the departure from pure thermal...

On topological properties of vacuum defects in lattice Yang–Mills theories
Abstract We study correlation between topological fermionic modes and center vortices in lattice Yang–Mills theory. The measurements are performed on the original configurations, without any smoothing of the fields which allows to study dependence...

On first-order formalism in string theory
Abstract We consider the first-order formalism in string theory, providing a new off-shell description of the non-trivial backgrounds around an “infinite metric”. The OPE of the vertex operators, corresponding to the background fields in some...

Microsphere near-field nanostructuring using picosecond pulses
Abstract In laser material processing the use of nonlinear multi-photon and near-field effects allows to produce nanostructures smaller than the wavelength of the processing laser. In the near-field of small particles locally restricted field...

Fractals meet fractals: self-avoiding random walks on percolation clusters
Abstract The scaling behavior of linear polymers in disordered media, modelled by self-avoiding walks (SAWs) on the backbone of percolation clusters in two, three and four dimensions is studied by numerical simulations. We apply the pruned-enriched...

MusrSim and MusrSimAna - Simulation Tools for μSR Instruments
Abstract We present the most recent developments inmusrSim (the simulation tool for μSR instruments and beamlines), namely the implementation of light transport and detection. We introduce also a companion program, musrSimAna, used for analysing the ...

Cassini-oval Description of the Energy Balance at Scission During 235U(nth, f)
Abstract For a detailed description of the excitation energy of the fission fragments, that is used to evaporate neutrons and emit γ-rays, realistic nuclear shapes at scission are necessary. It is shown that the nuclear shapes around the scission...

Magnetic lock-in phase transition in Tb0.95Er0.05Ni5 driven by low magnetic fields
Abstract The magnetic properties of a mixed inter-metallic compound, Tb0.95Er0.05Ni5, were investigated using a neutron diffraction method at low temperatures. These compounds were known to have a successive magnetic phase transition from the...
