What is a quantum particle called?
There are two classes of quantum particles, those with a spin multiple of one-half, called fermions, and those with a spin multiple of one, called bosons. Electrons, protons, and neutrons are fermions.
Can quantum particles travel back in time?
Aspects of modern physics, such as the hypothetical tachyon particle and certain time-independent aspects of quantum mechanics, may allow particles or information to travel backward in time.
Is dark energy the same as vacuum energy?
“Dark energy” is a term that encapsulates everything that may be accelerating the expansion of Universe, and “vacuum energy” is a kind of energy that permeates the whole Universe and may be taken into account as a contribution for the dark energy.
What are quantum energy levels?
a possible value of the energy of a quantum system, that is, a system consisting of microparticles and obeying the laws of quantum mechanics. The mircoparticles may be electrons, protons, or other elementary particles, as well as atomic nuclei, atoms, or molecules.
Is backwards causation possible?
Hence, the future is not determinate. Hence, backward causation is not possible.
What is a manifold in quantum chemistry?
The use of the word “manifold” in most of the quantum chemistry literature is purely as a synonym for multiple or different. Usually it appears when the number may be very large. Nothing more complicated than that. For a simpler example than coupled cluster, consider configuration interaction with only single excitations (CIS).
How to view a quantum manifold with a Euclidean coordinate system?
By this requirement, zooming into a quantum manifold should allow you to view it with a Euclidean coordinate system. For the quantum part: A quantum system consists of quantum states that can be described by a coordinate system. They are vectors in n dimensional space, where n is the number of coordinates.
What is a higher dimensional manifold?
A manifold can have a dimension, so “higher dimensional manifolds” might make sense when it is clear what we’re comparing when we say that the dimensionality of one manifold is higher than that of another.
What is the shape of a quantum system?
For the quantum part: A quantum system consists of quantum states that can be described by a coordinate system. They are vectors in n dimensional space, where n is the number of coordinates. The shape can be very complex, but locally it should be Euclidean. 25 insanely cool gadgets selling out quickly in 2021.
