On the Aharonov-Casher system subject to a Coulomb-type potential
The European Physical Journal Plus - Tập 131 - Trang 1-8 - 2016
By considering the confinement of the Aharonov-Casher system to a Coulomb-type potential, we show that the energy levels depends on the Aharonov-Casher geometric phase and obtain the persistent spin currents. Besides, we investigate the influence of the Coulomb-type potential on the Landau-Aharonov-Casher system by showing that bound states solutions to the Schrödinger-Pauli equation can be obtain...... hiện toàn bộ
Preliminary investigation of the multivariate relations between program-selected forbush decreases, worldwide lightning frequency, sunspot number and other solar-terrestrial drivers
The European Physical Journal Plus - Tập 137 - Trang 1-19 - 2022
Solar wind disturbances such as coronal mass ejections and their interplanetary counterparts and corotating interaction regions are interconnected with solar-terrestrial parameters such as cosmic rays, solar wind, geomagnetic storm, lightning, interplanetary magnetic field, among others. Data selection remains a challenging problem in solar-terrestrial studies. While manual selection of Forbush de...... hiện toàn bộ
Bertotti-Robinson thin-shell wormhole is physical but unstable
The European Physical Journal Plus - Tập 131 - Trang 1-6 - 2016
I construct a thin-shell wormhole in the spherically symmetric, static Bertotti-Robinson magnetic universe which is supported by normal matter in the sense that the energy conditions are all satisfied. Using the so called small velocity perturbation it is shown that this thin-shell wormhole is basically physical but unstable against radial perturbation.
Lorentz invariant quantum concurrence for $$\textit{SU}(2) \otimes \textit{SU}(2)$$ spin–parity states
The European Physical Journal Plus - Tập 135 - Trang 1-14 - 2020
The quantum concurrence of $$\textit{SU}(2) \otimes \textit{SU}(2)$$ spin–parity states is shown to be invariant under $$\textit{SO}(1,3)$$ Lorentz boosts and O(3) rotations when the density matrices are constructed in consonance with the covariant probabilistic distribution of Dirac massive particles. Similar invariance properties are obtained for the quantum purity and for the trace of unipotent...... hiện toàn bộ
Improving variational mass-consistent models of hydrodynamic flows via boundary conditions
The European Physical Journal Plus - Tập 127 - Trang 1-17 - 2012
Variational mass-consistent models for the velocity field v have been used by mesoscale meteorological community to modeling the wind field from an observed field v
0 in a bounded region Ω with boundary Γ. Variational calculus reduces the problem to the solution of an elliptic equation for a Lagrange multiplier λ subject to Dirichlet Boundary Condition (DBC) on flow-through...... hiện toàn bộ
Phòng thí nghiệm dưới lòng đất tại Trung Quốc Dịch bởi AI
The European Physical Journal Plus - Tập 127 - Trang 1-3 - 2012
Bài viết tổng hợp các phòng thí nghiệm dưới lòng đất và các thí nghiệm vật lý hạt ở Trung Quốc. Phòng thí nghiệm dưới lòng đất Jinping ở núi Jinping, Tứ Xuyên, Trung Quốc là phòng thí nghiệm dưới lòng đất sâu nhất thế giới với lối vào nằm ngang. Độ dày lớp đá che chở trong phòng thí nghiệm này vượt quá 2400 m. Lưu lượng tia vũ trụ và độ phóng xạ của các mẫu đá địa phương được đo là rất thấp. Các t...... hiện toàn bộ

Anisotropic strange quark stars with a non-linear equation-of-state
The European Physical Journal Plus - Tập 134 - Trang 1-8 - 2019
We obtain an exact analytical solution to Einstein’s field equations assuming a non-linear equation-of-state and a particular mass function. Our solution describes the interior of anisotropic color flavor locked strange quark stars. All energy conditions are fulfilled, and therefore the solution obtained here is a realistic solution within General Relativity. The mass-to-radius profile is obtained...... hiện toàn bộ
Solutions of Schrodinger equation with generalized Cornell potential (GCP) and its applications to diatomic molecular systems in D-dimensions using extended Nikiforov–Uvarov (ENU) formalism
The European Physical Journal Plus - Tập 137 - Trang 1-11 - 2022
The D-dimensional Schrodinger equation with generalized Cornell potential (GCP) is transformed into a form that is compatible with extended Nikiforov–Uvarov (ENU) method, and its approximate solutions are obtained using this formalism. The energy spectrum for the GCP is obtained in closed form, and the wave function is determined using the biconfluent Heun differential equation. Some numerical res...... hiện toàn bộ
RETRACTED ARTICLE: A critical assessment of extreme events trends in times of global warmingAbstract This article reviews recent bibliography on time series of some extreme weather events and related response indicators in order to understand whether an increase in intensity and/or frequency is detectable. The most robust global changes in climate extremes are found in yearly values of heatwaves (number of days, maximum duration and cumulated heat), while ... ... hiện toàn bộ
