Well-separated soliton-antisoliton pairs with an adjoint Higgs field in 4D space

Physics Letters B
We present single soliton states and soliton-antisoliton states with an adjoint Higgs field in 4D flat space. The action of a single soliton state diverges, while the action of soliton-antisoliton states converges.

Online Gradient Descent for Kernel-Based Maximum Correntropy Criterion

Entropy, 2019
In the framework of statistical learning, we study the online gradient descent algorithm generated by the correntropy-induced losses in Reproducing kernel Hilbert spaces (RKHS).

Quantum-critical scaling and temperature-dependent logarithmic corrections in the spin-half Heisenberg chain

, 1996
Low temperature dynamics of the S=1/2 Heisenberg chain is studied via a simple ansatz generalizing the conformal mapping and analytic continuation procedures to correlation functions with multiplicative logarithmic factors.

Phenomenology of ageing in the Kardar-Parisi-Zhang equation

, 2012
We study ageing during surface growth processes described by the one-dimensional Kardar-Parisi-Zhang equation. Starting from a flat initial state, the systems undergo simple ageing in both correlators and linear responses and its dynamical scaling is ...

Logarithmic Corrections for Spin Glasses, Percolation and Lee-Yang Singularities in Six Dimensions

, 1998
We study analytically the logarithmic corrections to the critical exponents of the critical behavior of correlation length, susceptibility and specific heat for the temperature and the finite-size scaling behavior, for a generic $\phi^3$ theory at its ...

A two-tensor model with order-three

European Physical Journal C: Particles and Fields
We construct a two-tensor model with order-3 and present its W-representation. Moreover we derive the compact expressions of correlators from the W-representation and analyze the free energy in large N limit.

Scaling laws for molecular communication

, 2014
In this paper, we investigate information-theoretic scaling laws, independent from communication strategies, for point-to-point molecular communication, where it sends/receives information-encoded molecules between nanomachines.

A Logarithmic Quantization-Based Image Watermarking Using Information Entropy in the Wavelet Domain

Entropy, 2018
Conventional quantization-based watermarking may be easily estimated by averaging on a set of watermarked signals via uniform quantization approach. Moreover, the conventional quantization-based method neglects the visual perceptual characteristics of ...

Testing logarithmic violations to scaling in strongly coupled QED

, 1996
Using very precise measurements of the critical couplings for the chiral transition of non compact $QED_4$ with up to 8 flavours, we analyse the behaviour of the order parameter at the critical point using the equation of state of a logarithmically ...
