Physicists at TU Dortmund University demonstrate non-local synchronization of electron-nuclear spin oscillations, opening routes to controllable spin networks. Many time crystals can form in the same material and synchronize their oscillations, even at distances exceeding one thousand times the size of an individual oscillator.
Researchers observe a fully coherent quantum dance between light-induced electronic excitations and crystal lattice vibrations in perovskite nanocrystals. The interaction between excitons and phonons is found to remain well-defined at low temperatures, enabling the evolution of quantum coherence for up to 10 picoseconds.
Researchers have developed a method to generate and detect sound waves at sub-terahertz frequencies using optically driven devices. The discovery was made possible by launching shear hypersound pulses with exceptionally large amplitudes in metal halide perovskites.
Researchers periodically drove a time crystal and observed a range of nonlinear dynamic behaviors, from perfect synchronization to chaotic motion. The team discovered the 'Farey tree sequence' and the 'devil's staircase,' which indicate specific patterns of behavior in response to periodic driving.
A study by Professor Graf-Vlachy's team found that CEOs with high levels of narcissism appoint managers who mirror their own traits, resulting in a 18% increase in narcissism among new hires. This leads to higher turnover rates and increased costs for companies.
Researchers at TU Dortmund University have developed a highly durable time crystal that outlasts previous experiments by tens of thousands of times. The team discovered a way to stabilize the crystal using nuclear spins, enabling it to maintain its periodic behavior for up to 40 minutes.
