"Unraveling the Paradox: Aristotle's Icebreaker Explores Quantum Systems' Logic-Defying Freeze"

Originally Published 2 years ago — by SciTechDaily

Researchers have investigated the Mpemba effect in quantum systems, where hotter water can freeze faster than cooler water. They found that the quantum Mpemba effect retains memory of its initial conditions, affecting its thermal relaxation later. By using two systems with quantum dots, the team demonstrated the thermal quantum Mpemba effect across various conditions, suggesting potential broader applications beyond thermal analysis. The findings encourage further exploration of the quantum Mpemba effect in future applications.

The Mpemba Effect: Does Hot Water Freeze Faster?

Originally Published 2 years ago — by Phys.org

Researchers from Kyoto University and the Tokyo University of Agriculture and Technology have investigated the Mpemba effect, which refers to the phenomenon of hot water freezing faster than cold water. They studied the effect in quantum systems by preparing two systems with quantum dots connected to a heat bath. By observing the time evolution of these systems, they found evidence of the thermal quantum Mpemba effect, where the hotter part becomes colder and vice versa. The researchers believe that these findings could have potential applications beyond thermal analyses.
