Preface:
Heat is one of the fundamental topics of Natural Sciences and Whole of Physics. But heat has different definitions according to the different versions of Physics.
According to Classical Physics:
Heat transfers from one place to another in the form of radiation.(Vacuum State)
According to Quantum Physics:
Heat can be transferred through vaccum without forming radiation.
I know the physics is getting messed up. But you all have to understand that, It’s Quantum Physics! So, we gonna be talking which will and is illogical!
=======================================================
Now we get to our question ‘How on earth Quantum Physics does that?’ It is really a new part of Quantum Physics. Only 2 years old. The research paper was published in 2019 by Stanford University.
I came across with research and I am explaining in common human language ‘How it’s done!’
Main:
Example:
Imagine! You waked up in the morning. Today, your beautiful wife made a lovely warm black coffee for you with her lovely hands. Now you hold the mug and it is really warm. You said, Darling, Oh! I love you! Thanks for the Coffee!.
Explanation:
‘How did you felt the coffee as warm?’Good Question! You felt the temperature, cause the molecules in the coffee shaked and gave heat as energy to the side molecule and then the other gave the other and so forth. Then the mug got involved in this love story and they also gave each other something! Then you hand jumped in the ceremony of giving and you felt the warmness of the Coffee.
(Classical Physics)
===================================================
Now you can see that it is one the fundamental way ‘How heat travels in classical physics.
In vacuum, heat travels in the form of radiation.(Classical Physics)
===========================================================================
Then what does this stupid ‘Quantum Physics do?’ Good Question! It does something which makes 0 sense in human life but larger sense in Civilized Human Life.
Why we need to know this question’s answer?
-Cause we use rockets in missiles, ICBM and Satelites and Don’t forget Elon Musk. He also needs one!
-------------------------------
Normal Vacuum:
It means the absence of particles and properties. It means ‘Nothing’. Like when you have a crush for the beautiful girl but there is 0 chance she will be your Girlfriend.
Abnormal Vacuum:
It still means absence of particles. It adds, it has some fleeting electromagnetic waves and particles which pop in and out into existence.Like the girl you have a crush on. There is a chance she loves your smile and she can ever love you.
Single Don’t kill me. But nowadays it is the most best form of explaining something. And everyone loves beautiful girls. Unless you are part of some sort of community.
------------------------------------
There should be couple of questions that I raised when I was talking about ‘Quantum Vacuum’
-Quantum Vacuum Energy
-Quantum Fluctuation
-Zero point energy
What is Quantum Vacuum Energy?
-The vacuum energy is a special case of zero point energy that relates to the Quantum Vacuum.
What is Quantum Fluctuation?
-A quantum fluctuation is the apperance of energetic particle from empty space. Cause Hisenberg Principle.
What is Zero-point energy?
-Zerp-point is the lowest energy that a Quantum Mechanical system may have.
Now when I finished talking and explaining the topics of the research paper I will end my giving a summary of the research paper.
Summary:
In 2019,Dec 11, Researchers at Stanford University. They invented the concept and proved the fact that heat travels differently in Quantum Vacuum.
Physicists showed that little vibrations of heat can travel upto several nanometers. The experiment exploited an uncanny feature of Quantum Vacuum that it is not empty.
Hao Jun Li said, They showed that two objects are able to communicate between two of them, for example hundreds of nanometers. Even though it is considered as infinitesimal for humans.
In 2011 study found out that Quantum Vacuum might me able to carry heat through molecular vibrations.
Applied Physics Letter, pointed out that Quantum Vacuum is understood as a place of rolling energy.Random fluctualtions of matter or energy can pop up or and disappear in small scale.Generally in small scale that people can imagine.
These fluctuations are chaotic and unpredictable. But they still can support as the stepping stone for carrying energy.In our case heat. In the form of Quantum excilation known as phonon(In physics, it is considered as a collective excilations in periodic, elastic arrangement of atoms or molecules in a condensed form of matter like solid and some liquids)-gap. If you aare a phonon then if you wanted to jump from an inch gap. The chances are low that the right fluctuations will happen. But if we reduce it to nanometers then the chances improve and you can carry heat easily. The researchers showed the best gap would be 5 nanometers.
This weird hopscotch can greatly improve the way we transfer heat across empty space. Outpacing even electromagnetic radiation. Which was previously thought as the only way to transfer heat in vacuum.
That’s it!
Conclusion:
The researcher paper even had proofs and ‘How the experiment should be conducted for falsification test’ But it was not subject to my article. If the article seems interesting to you guys then tell me. I would consider to add an experiment version. I am writing about physics after 3 months. So, the way kinda changed of my writing. Still I added more information than ever. Cause previously I use to do fun and be sarcastic a lot. Which I know you guys loved. But being serious is more good.
