Higgs mode in superconductors
Web20 de jan. de 2024 · This Higgs mode is a state of matter found at the quantum scale of atoms, their electronic states and energetic excitations. The mode can be accessed and controlled by laser light flashing on the superconductor at terahertz frequencies of trillions of pulses per second. WebHiggs mode are amplitude oscillations of a quantum field. Effective Lorentz symmetry is necessary. Collective excitations in a quantum many-body systems Consequence of a spontaneous breaking of a continuous symmetry. Which identified systems? -Superconductors (locally gauge invariant)
