Topological charge distributions in 2 dimensional CP 2 model with θ-term is calculated. In strong coupling regions, topological charge distribution is approximately given by Gaussian form as a function of topological charge and this behavior leads to the first order phase transition at θ = π. In weak coupling regions it shows non-Gaussian distribution and the first order phase transition disapp...

typically, two configurations are used for energy harvesting, with different advantages: piezoelastic and piezomagnetoelastic. best performance of piezoelastic configuration is limited to its narrow bandwidth around the resonance frequency. if the excitation frequency slightly deviates from the resonance frequency, the power-out is severely reduced. to overcome this, the piezomagnetoelastic has...

The parametric resonance of the axial vibrations of a cantilever pipe conveying harmonically perturbed two-phase flow is investigated using the method of multiple scale perturbation. The nonlinear coupled and uncoupled planar dynamics of the pipe are examined for a scenario when the axial vibration is parametrically excited by the pulsating frequencies of the two phases conveyed by the pipe. Aw...

A recent experiment [Nadj-Perge et al., Science 346, 602 (2014)] provides evidence for Majorana zero modes in iron (Fe) chains on the superconducting Pb(110) surface. Here, we study this system by scanning tunneling microscopy using superconducting tips. This high-resolution technique resolves a rich subgap structure, including zero-energy excitations in some chains. We compare the symmetry pro...

Topological resonance energy (TRE) is a theoretical index which was discovered a few years ago1,2 and which can be used for describing the aromaticity and related properties of conjugated n-electron systems. Although the TRE method has limitations and fails in the case of some conjugated radicals and ions3, for a large number of systems of interest in chemistry (i. e. singlet ground state molec...

We consider a breathing Kagome lattice with complex hoppings by imposing $$ \mathbb {Z}_{3}$$ clock symmetry in the complex-energy plane. It is non-Hermitian generalization of second-order topological insulator characterized emergence corner states. construct states $$\mathbb clock-symmetric model. also shown that model realized an electric circuit properly designed, where are observed impedanc...

Clonidine has two aromatic rings in which halogens are attached to one ring in this study, both in drug state and in fullerene nanostructure, and by changing the type of halogen at the * HF / 6-31G level and in The gas phase was first optimized and then the NBO calculations were performed. The results obtained in N61, N63 and N5, N3 indicate the highest rhizanese energy and load transfer that, ...

Several measures of aromaticity including energetic, magnetic, and electron density criteria are employed to show how aromatic stabilization can explain the stability sequence of hydroporphyrins, ranging from porphin to octahydroporphin, and their preferred hydrogenation paths. The methods employed involve topological resonance energies and their circuit energy effects, bond resonance energies,...
