A German-Japanese research team applies quantum geometry to non-Hermitian photonic systems, introducing a new degree of complexity. They develop a method to measure the quantum metric directly, enabling the creation of programmable artificial potentials for light and new design possibilities for photonic systems.
Koun Shirai bridges conventional physics and nonequilibrium materials to provide robust thermodynamic description of glasses. He redefines equilibrium as energy extraction impact, allowing tools of thermodynamics to apply to glasses.
Researchers at the University of Surrey discovered evidence of opposing arrows of time emerging from quantum systems. The study suggests that time's arrow may not be fixed, and instead could flow in both forward and backward directions due to processes taking place at the quantum level.
Scientists at the Paul Scherrer Institute have found a quantum phenomenon known as time-reversal symmetry breaking occurring at the surface of the Kagome superconductor RbV₃Sb₅ at temperatures up to 175 K. This discovery sets a new record for the temperature at which this phenomenon is observed among Kagome systems.
A research team from USTC has demonstrated the realization of time reversal through input-output indefiniteness in a photonic system, achieving a high success probability of 99.6%. This breakthrough shows significant advantages over traditional methods and opens up new possibilities for quantum information and photonic technologies.
Researchers at Rice University have discovered a way to transform a rare-earth crystal into a magnet by using chirality in phonons. Chirality, or the twisting of atoms' motion, breaks time-reversal symmetry and aligns electron spins, creating a magnetic effect.
Researchers at CUNY ASRC detail a breakthrough experiment in which they observed time reflections of electromagnetic signals in a tailored metamaterial. The effect causes a significant portion of the broadband signals to be instantaneously time reversed and frequency converted, forming a strange echo.
Researchers demonstrate spontaneous time-reversal symmetry breaking in a cavity quantum electrodynamics system using dipole interaction. Exceptional points are identified at critical thresholds, exhibiting robust dynamics and topological protection.
Researchers observed a long-theorized exception to time reversal symmetry, finding certain particle types change into one another six times more often in one direction than the other. The BaBar experiment provided clear conditions for a direct measurement of time violation, confirming quantum field theory.
