How Quantum State Transitions Differ from Classical?

A quantum phase transition (QPT) is a fundamental shift in the state of a material that occurs at absolute zero temperature. Unlike classical phase transitions driven by temperature or pressure, QPTs are driven by quantum fluctuations. This video introduces the nature of QPTs, their implications, and their significance in understanding new materials and technologies.

How do quantum fluctuations differ from thermal fluctuations in driving phase transitions? How do entanglement and quantum correlations change near a quantum critical point?

If time keeps moving on slower and slower, would it really stop. At extremely short time spans would a rolling bowling ball or a floating particle of dust be just teleporting one extremely short distance at a time.
If something that is moving never did teleport at extremely short time spans, there would be no present, just the past, therefore we could not exist because our consciousness does not exist in the past. Time spans that are too short for us to be able to take any notice of still flow smoothly with out jumping. Say we don’t become self aware until a certain amount of time goes by like a 20th of a second, that means our self awareness would be like a cartoon book that is getting flipped through, where each page is a 20 second interval. Even If our consciousness was made up of these still pages of the cartoon book, we still wouldn’t be conscious because it doesn’t matter how fast the pages get flipped through each page is still, and our consciousness is never still no matter how fast the pages get flipped through.
To us 1 second feels like 1 second second. If a 20th of a second feels like 1 second to us, would 1 second therefore feel like 20 seconds to the physical world such as moving molecules or dust particles.
Let’s say it takes 1 second for a dust particle to move a centre metre. If we see it as taking 20 seconds to move a centre metre, the particle of dust might feel like it has taken a 20th of a second to move a centre metre. The shorter time span we would experience, the faster time would be moving on according to the floating dust particle. If this was the case, then the floating dust particle would not have to teleport at extremely short time spans.

e to the power of x is meant to be 2.718 to the power of x. So how can a point on the slope of e to the power of x be (2, 7.4)? 2.718 to the power of 2 is not 7.4.

e is meant to be 2.718. (1+1/x) to the power of x, which is what e is meant to equal, doesn’t equal 2.718.

Yeah, and my grandmother has bionic hips. You people are living in an Alice and Wonderland world, where Santa Claus is the quantum president on crack.
