A new theoretical approach is proposed to explain the nature of the well-known narrow and intense optical J-band of ...

Two-photon emission (2PE) is a process in which an electron transition between quantum levels occurs through the simultaneous emission of two photons. Two-photon emission is interesting because it ...

to \(E_{1}\) the energy of the photon can be worked out using the following: As the energy levels have different values, each of the possible electron transitions within an atom will produce a ...

Recent studies have focused on understanding the interactions between these charge carriers, including electron-phonon coupling, Coulomb drag effects, and structural phase transitions, which are ...

This creates vacancies, leading to a cascade of electron transitions within the atom as electrons from higher energy levels drop down to fill the vacancy. The energy released during these transitions ...

It came when the one electron of the hydrogen atom transitioned ... Conventional quantum mechanics didn't have such transitions, and Dirac's relativistic Schrödinger equation (naturally called ...
