Physicists crack the math connecting ultraslow quantum magnetism to ultrafast black-hole physics
A team led by University at Buffalo physicists has found a mathematical solution that shows how a frustrated quantum magnet can transition from ultraslow behavior to ultrafast, highly entangled behavior resembling that of a black hole.
Physicists at the University at Buffalo have discovered a mathematical connection between ultrasmall quantum magnetism and ultrafast black hole physics. The team's solution reveals how a frustrated quantum magnet can transition from ultra-slow behavior to highly entangled behavior, similar to that of a black hole. This finding links spin glasses—states of matter characterized by disordered magnetic spins—to the SYK model, which describes fast, entangled states used to study black hole physics and quantum chaos.
Dr. Jamir Marino, lead author of the study published in Physical Review Letters, explains that the team found that as quantum fluctuations increase at extremely low temperatures, a spin glass can transition from slow, information-preserving dynamics to fast, rapidly scrambling dynamics described by the SYK model. This unexpected result suggests that quantum effects can "melt" the spin glass, causing particles to become highly entangled and lose their individual identities.
The discovery could help improve the control of information storage and spread in quantum technologies.
