Discovery of a hidden quantum critical point in two-dimensional superconductors

Weak fluctuations in superconductivity, a precursor phenomenon to superconductivity, have been successfully detected by a research group at the Tokyo Institute of Technology (Tokyo Tech). This breakthrough was achieved by measuring the thermoelectric effect in superconductors over a wide range of magnetic fields and over a wide range of temperatures, from much higher than the

Study outlines spectroscopic signatures of fractionalization in octupolar quantum spin ice

Quantum spin liquids are fascinating quantum systems that have recently attracted significant research attention. These systems are characterized by a strong competition between interactions, which prevents the establishment of a long-range magnetic order, such as that observed in conventional magnets, where all spins align along the same direction to produce a net magnetic field.Quantum Physics
