It sounds like one of the easiest experiments possible: Take two cups of water: one hot, one cold. Place both in a freezer and note which one freezes first. Common sense suggests that the colder water ...

The genuine quantum Mpemba effect in a many-qubit system manifests at different timescales. Credit: Physical Review Letters (2024). DOI: 10.1103/PhysRevLett.133.140404 Initially investigating out of ...

Then the experiment #3 proceeds to demonstrate mpemba effect on water that froze through the frost in the fridge. Then the experiment #8 had shown that if you use different waters, you can make mpemba ...

Does hot water freeze faster than cold water? On its face this idea seems like it should be ridiculously simple to test, and even easier to intuit, but this question has in fact had physicists arguing ...

The question I have is - under which conditions would you say that the experiment shows the reasoning wrong, instead of experiment itself having been 'done wrong'? For example - if you do something as ...

Physicists have developed a new theoretical framework which unifies a wide array of seemingly unrelated "Mpemba effects": counterintuitive cases where systems driven further from equilibrium relax ...

The Mpemba effect is originally referred to the non-monotonic initial temperature dependence of the freezing start time, but it has been observed in various systems -- including colloids -- and has ...

Kyoto, Japan -- Does hot water freeze faster than cold water? Aristotle may have been the first to tackle this question that later became known as the Mpemba effect. This phenomenon originally ...

Heating up Physicists have shown that a colder trapped-ion qubit can warm-up faster than a hotter qubit. (Courtesy: Shutterstock/Evgenia-Fux) The inverse Mpemba ...

Not every scoop of ice cream can be described as “fateful.” But a batch of ice cream Erasto Mpemba made as a teenager in Tanzania in 1963 made waves in physics that are still being felt nearly 60 ...

Researchers from Trinity College Dublin have just described the existence of the paradoxical Mpemba effect within quantum systems. Initially investigating out of pure curiosity, the discovery has ...
