Non-Perturbative Renormalization Group and Quantum Tunnelling
Ken-Ichi Aoki, Atsushi Horikoshi, Masaki Taniguchi +1
The non-perturbative renormalization group (NPRG) is applied to analysis of tunnelling in quantum mechanics. The vacuum energy and the energy gap of anharmonic oscillators are eval…
Running of Soft Parameters in Extra Space-Time Dimensions
Tatsuo Kobayashi, Jisuke Kubo, Myriam Mondragon +1
The evolution of the parameters including those in the soft supersymmetry-breaking (SSB) sector is studied in the minimal supersymmetric standard model (MSSM) with a certain set of…
Background Configurations, Confinement and Deconfinement on a Lattice with BPS Monopole Boundary Conditions
E. -M. Ilgenfritz, S. V. Molodtsov, M. Müller-Preussker +1
Finite temperature SU(2) lattice gauge theory is investigated in a 3D cubic box with fixed boundary conditions provided by a discretized, static BPS monopole solution with varying…
Finite Temperature LGT in a Finite Box with BPS Monopole Boundary Conditions
E. -M. Ilgenfritz, S. V. Molodtsov, M. Müller-Preussker +1
Finite temperature SU(2) lattice gauge theory is investigated in a 3D cubic box with fixed boundary conditions (b.c.) provided by a discretized, static BPS monopole solution with v…
Remarks on square functions in the Littlewood-Paley theory
Shuichi Sato
We prove that certain square function operators in the Littlewood-Paley theory defined by the kernels without any regularity are bounded on Lp spaces.
Embedded Topological Defects in Electroweak Theory: From Percolating Networks to Sphalerons
M. N. Chernodub, F. V. Gubarev, E. -M. Ilgenfritz +1
New defects (Z-vortices and Nambu monopoles) are found to become thermodynamically relevant for the broken phase near to the (weakly first order) electroweak phase transition, and…
