Phys.org February 9, 2024 Detecting the Bragg glass phase has been challenging despite its sharp theoretical definition in terms of diverging correlation lengths. A team of researchers in the US (Cornell University, Stanford University, National Accelerator Laboratory, Argonne National Laboratory provided bulk probe evidence supporting a Bragg glass phase in the systematically disordered charge-density-wave material of PdxErTe3. They established a diverging correlation length in samples with moderate intercalation over a wide temperature range. According to the researchers their work advances our understanding of the complex interplay between disorder and fluctuation and the use of their analysis technique to target fluctuations […]

‘Back to basics’ approach helps unravel new phase of matter
Science Daily September 27, 2021 It was thought that the properties of prethermal discrete time crystals (DTCs) were reliant on quantum physics. An international team of researchers (UK, Germany) found that a simpler approach, based on classical physics can be used to understand these mysterious phenomena. Using a computer simulation they studied many interacting spins under the action of a periodic magnetic field using classical Hamiltonian dynamics. The resulting dynamics showed in a neat and clear way the properties of prethermal DTCs: for a long time, the magnetization of the system oscillates with a period larger than that of the […]
