In the framework of gauge/gravity duality, and in particular $AdS_3/CFT_2$ correspondence, we study one-dimensional superconductors analyzing dual (1+2)-dimensional gravity presence Einstein-power-Maxwell non-linear Electrodynamics. probe limit compute critical temperature transition as a function mass scalar field. The computation is performed analytically employing Rayleigh-Ritz variational p...

An energy-based solution for calculating the buckling loads of partially anisotropic stiffened plates is presented, such as antisymmetric cross-ply and angle-ply laminations. A discrete approach, mathematical modelling formulations plates, followed. The developed extend Rayleigh–Ritz method explore available unstiffened plate solutions to interesting cases with some degree material anisotropy. ...

In this research, we analyze the acoustic–vibration coupling of liquid-filled cylindrical shells under complex excitations. A calculation model to determine acoustic characteristics and steady-state response a shell coupled an cavity is proposed. The displacement sound pressure are described by Chebyshev–Fourier series in three dimensions. uncertain expansion coefficient determined with Rayleig...

We study the band structure of semiconductor nanowires with quantum dots embedded in them. The is calculated using Rayleigh–Ritz variational method. consider two different types, one type defined by electrostatic potentials applied to nanowire, while other adding materials offsets respect parameters nanowire. are particularly interested appearance discrete energy levels gap between conduction a...
