Quantum optical application of Pascal Principle

In summary, DaTario is asking if the Pascal principle, which states that pressure is equal in all directions in a confined fluid, is still valid in a quantum optical context where light pressure effects are taken into account. They provide a thought experiment with thin wires in an U tube with different terminal areas as a potential proof of the finiteness of space nature. They also question if this principle can be observed experimentally with light, which is considered a field with infinitely many degrees of freedom. Marlon does not directly answer the question, but instead poses a question about the behavior of light in this scenario.

Hello,

Supose you have an U tube, in which the inner walls are made absolutelly reflective. Now, put a termical state (temperature T) for the radiation field inside the tube and close it with reflective discs which can slide without friction. Supose further that de diameter of the tube in its terminations are not equal. For the sake of definiteness, let's assume 2 sq meters cross section in one side and 10 sq meters in the other. My question is: Taking into account light pressure effects, is the Pascal principle valid in this quantum optical context ?


Best Regards

Why do you think that light exhibits "different" behaviour in this case ?

Hi,

Suppose you have an U tube with different areas (A1 and A2) in its terminals.
Thinking mechanically (not with photons) , now imagine you start to put thin wires through this tube, the length of which are exactly equal to the tube. Suppose this wires do not have friction with one another, so that they can slide freely along.

In the limit where these wires become geometrical lines, you will have the U tube filled with infinitely many wires, each one going from A1 to A2. Applying a force F in one end of a given wire will require an equal force F at the other end of the same wire in order to maintain the equilibrium. As it happens to all wires we may say that if forces comunicate with continuum density from one plate (A1) to the other (A2), the equilibrium condition will not be p1 = p2 but F_r1 = F_r2, where F_r is resultant.
This gedanken experiment seems to me to act like a proof of the finiteness of the space nature, specifically in what concerns force propagation.

As light is thought to be a field, with infinitelly mane degrees of freedom, it occurs to me to ask if experimentally this principle of equal pressure will show up.

Best wishes

DaTario
 

1. What is Quantum optical application of Pascal Principle?

Quantum optical application of Pascal Principle is the use of principles from quantum optics and Pascal's Principle to manipulate and control light at the quantum level. This involves studying the behavior of light as both a wave and a particle and using it to create advanced technologies such as quantum computers and quantum communication systems.

2. How does Pascal Principle apply to quantum optics?

Pascal Principle states that when pressure is applied to a confined fluid, it is transmitted equally in all directions. In quantum optics, this principle is used to manipulate light by controlling the flow of photons in a confined medium, similar to how pressure is transmitted in a confined fluid. This allows for precise control and manipulation of light at the quantum level.

3. What are some potential applications of Quantum optical application of Pascal Principle?

Some potential applications of this technology include quantum computing, quantum cryptography, and quantum teleportation. It can also be used in the development of advanced sensors, imaging techniques, and precision measurements.

4. What are the challenges in implementing Quantum optical application of Pascal Principle?

One of the main challenges is maintaining the delicate quantum state of light while manipulating it with precision. This requires advanced techniques and technologies, as well as highly controlled environments. Another challenge is scaling up these technologies for practical use, as they currently only work on a small scale.

5. How does Quantum optical application of Pascal Principle impact the field of quantum mechanics?

Quantum optical application of Pascal Principle provides a new way to study and manipulate light at the quantum level, which can further our understanding of quantum mechanics. It also opens up new possibilities for practical applications of quantum technologies, which can have a significant impact on various industries and fields of study.
