1. Researchers at the Max Planck Institute for the Structure and Dynamics of Matter have discovered a light-induced Meissner effect in YBa2Cu3O6.48 using laser pulses. 2. This effect allows the material to expel magnetic fields, similar to conventional superconductors, even at ambient temperatures. 3. The findings suggest that tailored light pulses could potentially induce superconductivity at much higher temperatures than previously possible.
