Electron-phonon coupling plays a significant role in the phenomenon of superconductivity, where materials exhibit resistance-free electrical conductance. The interaction between electrons and vibrations in a lattice, known as phonons, is crucial for the formation of Cooper pairs. These pairs of electrons are bound together via attractive interactions and condense into a coherent state, leading to
Photonic alloys, materials that combine two or more photonic crystals, show great promise in controlling the propagation of electromagnetic waves. However, one major limitation of these materials is light backscattering, which reflects light back in the direction it originated, hindering data and energy transmission. Overcoming this challenge is crucial for unlocking the full potential of
Discovering one Higgs boson was already a monumental task, but now scientists are faced with the challenge of finding two Higgs bosons in the same place at the same time – a process known as di-Higgs production. This intricate process sheds light on the self-interaction of the Higgs boson, specifically the measurement of its “self-coupling,”
