Phys.org January 26, 2023 The concept of quasiparticles has become a cornerstone of condensed quantum matter, where it explains a variety of emergent many-body phenomena such as superfluidity and superconductivity. Researchers in South Korea used quasiparticles to explain the collective behaviour of a classical system of hydrodynamically interacting particles in two dimensions. In the disordered phase of this matter, measurements revealed a subpopulation of long-lived particle pairs. Modelling and simulation of the ordered crystalline phase identified the pairs as quasiparticles, emerging at the Dirac cones of the spectrum. The quasiparticles stimulated supersonic pairing avalanches, bringing about the melting of the […]

Evidence for a new property of quantum matter revealed
Science Daily June 12, 2018 Quantum spin liquids do not achieve an ordered magnetic state, even at the lowest temperatures. An international team of researchers (USA – Johns Hopkins University, Georgia Institute of Technology, NSF, Argonne National Laboratory, Russia) studied an organic compound called k-(BEDT-TTF)2Hg(SCN)2 Br that may be both a spin liquid and a dipole liquid. They observed that in this quantum material even at super-cold temperatures, electrical dipoles are still present and fluctuate according to the laws of quantum mechanics. The discovery has potential application in quantum computing and information storage… read more. TECHNICAL ARTICLE
