  • The periodic modulation of the magnetic properties of magnonic crystals controls the flow of spin waves. An optical method is now shown that can produce such modulations by heating, which can be reprogrammed during operation.

  • In contrast to real atoms, Bose–Einstein condensation of quasi-particles does not require low temperature, but is obtained via external pumping. Here, the authors show an unexpected transitional dynamics of a Bose–Einstein condensate of magnons due to a nonlinear evaporative supercooling mechanism.

  • Studies of supercurrent phenomena, such as superconductivity and superfluidity, are usually restricted to cryogenic temperatures, but evidence suggests that a magnon supercurrent can be excited in a Bose–Einstein magnon condensate at room temperature.

  • Adding to the significant interest in quantum computing schemes, this work focuses on classical analogs for which entanglement is not required. Specifically, this work demonstrates through micromagnetic numerical simulations the use of wavevector-selective parametric pumping to controllably initialize and manipulate a room-temperature two-component magnon condensate on the Bloch sphere and reveals the possibility of Rabi-like oscillations in the wavevector domain.

  • The field of magnonics studies the dynamic excitations of a magnetically ordered material. This Review surveys coherent magnonics, discussing the design of spin-wave devices and the use of magnon Bose–Einstein condensates to enable a broad range of applications.
