‘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 […]
