Broad band solar cell absorber based on double-ring coupled disk resonator structure: from visible to mid infrared
Published in Physica Scripta
In this paper, a broad band absorber based on a double-ring coupled disk resonator periodic structure, which can work in the visible and mid infrared range, is proposed and investigated. Results show the absorbance is large than 92.4% in the range of 300 nm–4096 nm, and the average absorption is about 97.4% from the visible to mid-infrared bands. B...
Seismic metamaterials based on coupling mechanism of inertial amplification and local resonance
Published in Physica Scripta
Inertial amplification mechanisms could be used to control the propagation of elastic waves in beams and slabs, but it was a difficult problem to apply inertial amplification mechanisms to seismic metamaterials to design low-frequency broadband. This paper presents a inertially amplified locally resonant seismic metamaterial (IALR-SM) using the cou...
Fractional circuit network theory with n-V-structure
Published in Physica Scripta
This paper studies a class of circuit network model with fractional n-V-structure, the model contains several independent resistance elements, so it is the topology of multiple network models. First, this paper calculates the equivalent resistance of n-V circuit network by constructing equivalent model, and gives two closed equivalent resistance an...
Degeneration of N-solitons and interaction of higher-order solitons for the (2+1)-dimensional generalized Hirota-Satsuma...
Published in Physica Scripta
In this paper, the evolutionary behavior of N-solitons for a (2+1)-dimensional generalized Hirota-Satsuma-Ito equation is studied by using the Hirota bilinear method and the long wave limit method. Based on the N-soliton solution, we first study the evolution from N-soliton to T-order (T = 1, 2, 3) breather wave solutions via the paired-complexific...
Data-driven discovery of Caputo fractional order systems
Published in Physica Scripta
Due to the peculiar non-locality of fractional order differential and integral operators, Caputo fractional order systems are harder than integer order systems to be discoverd from data. To solve this open problem, we propose a framework of method capable of discovering Caputo fractional order (autonomous and non-autonomous) systems from measurable...
Spin-charge-coupled transverse resistance in an ambipolar conductor YH2-based Hall-bar structure with perpendicularly ma...
...Published in Physica Scripta
Spin-charge (SC) coupling is crucial in spintronics and the coupling mechanisms can be classified into bulk characteristic via spin-orbit interaction (SOI) or the interfacial characteristic provided by a junction formed by magnetic and nonmagnetic conductors. The two types of SC couplings account for the transverse resistance (TR) in a planer chann...
Measurement of hyperfine constants and the isotope shift of rubidium 5P1/2 excited-state using saturated absorption spec...
Published in Physica Scripta
The Saturated Absorption Spectroscopy (SAS) was performed to measure the hyperfine constants of rubidium 5P1/2 excited state using an external-cavity diode laser (ECDL) operating at 795 nm. We report our measurements for the magnetic dipole coupling constants 120.79(29) and 407.75(57) for 85 Rb and 87 Rb respectively. Our measurement of the 85 Rb h...

Published in Physica Scripta
The quantum information theoretic measures in terms of Shannon entropy and Fisher entropy (both in position and momentum spaces) on the ground, excited as well as virtual states arising out of the two-photon transitions (1s → nl; n = 2 − 4, l = 0, 2) of H atom embedded in classical weakly coupled plasma environment are done for the first time. Four...
On real and complex dynamical models with hidden attractors and their synchronization
Published in Physica Scripta
In this work, we propose three chaotic (or hyperchaotic) models. These models are real or complex with one stable equilibrium point (hidden attractor). Based on a modified Sprott E model, three versions were introduced: the complex integer order, the real fractional order, and the complex fractional order. The basic properties of these models have ...
