Geomagnetically induced currents (GICs) arise when rapid variations in the Earth’s magnetic field, driven by solar storms and substorms, induce electric fields in the ground. These surface electric ...

Risks posed by geomagnetic disturbance (GMD) and electromagnetic pulse (EMP) events add challenges to an already complex power system environment. But they remain crucial to address. How prepared is ...

We present the study of the SiGe quantum ring (QR) modeled by an anharmonic axially symmetric potential with a centrifugal core in the effective mass approximation. We show how the femtosecond laser ...
