A macroscopic collective motion of a Bose–Einstein condensate (BEC) is commonly associated with phenomena such as superconductivity and superfluidity, often generalised by the term supercurrent. Another type of motion of a quantum condensate is second sound—a wave of condensate’s parameters. Recently, we reported on the decay of a BEC of magnons caused by a supercurrent outflow of the BEC from the locally heated area of a room temperature magnetic film. Here, we present the observation of a… 

Magnon Bose–Einstein Condensate and Supercurrents Over a Wide Temperature Range

Magnon Bose–Einstein Condensates (BECs) and supercurrents are coherent quantum phenomena, which appear on a macroscopic scale in parametrically populated solid state spin systems. One of the most

Experimental observation of Josephson oscillations in a room-temperature Bose-Einstein magnon condensate

The alternating current (ac) Josephson effect in a time-independent spatially-inhomogeneous setting is manifested by the occurrence of Josephson oscillations - periodic macroscopic phase-induced

Spatial separation of degenerate components of magnon Bose–Einstein condensate by using a local acceleration potential

This work shows that motion of the clouds can be described well based on the peculiarities of magnon dispersion characteristics, and shows that, during the motion, the condensate cloud harvests non-condensed magnons, which results in a partial compensation of condensates depletion.

Confinement of Bose–Einstein magnon condensates in adjustable complex magnetization landscapes

Coherent wave states such as Bose–Einstein condensates (BECs), which spontaneously form in an overpopulated magnon gas even at room temperature, have considerable potential for wave-based computing

Direct evidence of spatial stability of Bose-Einstein condensate of magnons

Direct experimental evidence is provided for a repulsive interaction of magnons in the condensate resulting in its stabilization and a mechanism, which is responsible for this interaction, is proposed.

Bose-Einstein Condensation of Nonequilibrium Magnons in Laterally Confined Systems

A high density of weakly interacting quasiparticles can initiate a phase transition into a macroscopic Bose- Einstein condensate (BEC). Theory predicts that magnon condensation is unstable in

Bose–Einstein condensation of nonequilibrium magnons in confined systems

We study the formation of a room temperature magnon Bose–Einstein condensate (BEC) in nanoscopic systems and demonstrate that its lifetime is influenced by the spatial confinement. We predict how

The appearance of spontaneous coherence is a fundamental feature of a Bose-Einstein condensate and an essential requirement for possible applications of the condensates for data processing and

This article discusses two different coherent quantum phenomena of magnonic bosons: Bose–Einstein condensation (mBEC) and Superfluid State of Magnons (SSM). What is the difference between the two?

Stabilization of a nonlinear magnonic bullet coexisting with a Bose-Einstein condensate in a rapidly cooled magnonic system driven by spin-orbit torque

Bose-Einstein condensation in an ultra-hot gas of pumped magnons.

It is demonstrated that external pumping can create remarkably high effective temperatures in a narrow spectral region of the lowest energy states in a magnon gas, resulting in strikingly unexpected transitional dynamics of Bose-Einstein magnon condensate.

A comprehensive set of experiments giving compelling evidence for BEC of polaritons of bosonic quasi-particles are detailed, which indicate the spontaneous onset of a macroscopic quantum phase.

By using a technique of microwave pumping it is possible to excite additional magnons and to create a gas of quasi-equilibrium magnons with a non-zero chemical potential, and a Bose condensate of magnons is formed.

Observation of Bogoliubov excitations in exciton-polariton condensates

The observation of so-called Bogoliubov excitations provides the first sign of possible superfluid behaviour in an exciton-polariton condensate. Einstein’s 1925 paper predicted the occurrence of

Observations of a parametrically populated magnon gas in a single-crystal film of yttrium iron garnet by means of wave-vector-resolved Brillouin light scattering spectroscopy evidence a novel condensation phenomenon: A spontaneous accumulation of hybrid magnetoelastic bosonic quasiparticles at the intersection of the lowest magnon mode and a transversal acoustic wave.
