Magnon crystal
WebApr 15, 2024 · Magnons are bosonic quasiparticles satisfying Bose–Einstein distribution at thermal equilibrium. Due to their low energy consumption and long coherence length, spin waves or magnons are promising information carriers as an upgrade of electrons. 2–5 2. V. WebFeb 3, 2024 · The concept of space-time crystals (STC), i.e., translational symmetry breaking in time and space, was recently proposed and experimentally demonstrated for quantum systems. Here, we transfer this concept to magnons and experimentally demonstrate a driven STC at room temperature.
