jlcd said:id like to know how much is the momentum basis selected
bhobba said:I would say not at all. Most interactions, and that certainly would be the interactions in a cell, are radial in nature (ie have rotational symmetry) and it is well known that singles out the position basis.
Singling out the momentum basis is pretty much a contrived thing - not occurring naturally.
Thanks
Bill
jlcd said:Could you give an example of inducing a molecular system to choose momentum basis?
bhobba said:I have zero idea how to do that.
The only momentum outcomes I know of are contrived where you have a set-up designed to measure momentum.
Thanks
Bill
jlcd said:Can you give example of a simple quantum system where the momentum is measured.
bhobba said:Sure. Run an electron beam through a magnet an the circular path gives you the momentum. And no I can't really think of others - you will need to chat to an experimental type.
Thanks
Bill
jlcd said:Does this this running electron beam through a magnet an the circular path giving the momentum also give the position?
jlcd said:added: but momentum is supposed to be the energy of the atom..
bhobba said:It isn't. That's really basic classical physics.
Thanks
Bill
jlcd said:Mr. Hobba. The orbital angular momentum still use the position basis?? Then what is the momentum basis about?
bhobba said:Operators are basis independent, as are states.
Sometimes the momentum basis is better for solving problems than the position basis - mostly the wave-function which is a state expanded in terms of the position basis is used, but sometimes its better to use the momentum basis - especially in Quantum Field Theory.
Thanks
Bill
jlcd said:In QFT.. there is no position.. so no position basis is used..
Einselection, short for environment-induced superselection, is a process by which a quantum system becomes entangled with its surroundings, leading to the emergence of classical properties such as definite values for observable properties. In molecules, this process helps to explain why certain states are more stable and why certain molecular configurations are more likely to be observed.
Einselection occurs in molecules when the system interacts with its environment, causing the system to become entangled with the environment. This leads to the selection of certain states and configurations as the most stable and likely to be observed.
Einselection is significant in molecules as it helps to explain the emergence of classical properties from the quantum world. It also plays a role in determining the stability and behavior of molecules, as well as the likelihood of certain configurations being observed.
Yes, Einselection has been observed in various experiments involving molecules, such as in the decay of radioactive atoms and the behavior of molecular magnets. It has also been used to explain the stability of certain molecular configurations in nature.
Einselection is closely related to other quantum phenomena such as decoherence and entanglement. In fact, Einselection is a type of decoherence process that leads to the entanglement of a system with its environment. It also helps to bridge the gap between the quantum and classical worlds, as it explains how classical properties arise from the quantum behavior of molecules.
