Over the past decades, physicists worldwide have been trying to gain a better understanding of non-equilibrium dynamics in quantum many-body systems. Some studies investigated what are known as quasiparticles, disturbances ...
A team of physicists from Germany, Russia, Ukraine and the United Kingdom has found a new way to observe magnon-polarons by using a nanopatterned magnetic structure lit with short laser pulses. In their paper published in ...
A new theoretical study at Monash University has improved our understanding of the interplay between quantum and thermal fluctuations (or excitations) in quantum matter.
