Quantum particles Definition and 24 Threads

My article has been published in Entropy . Abstract: Schrödinger noticed in 1952 that a scalar complex wave function can be made real by a gauge transformation. The author showed recently that one real function is also enough to describe matter in the Dirac equation in an arbitrary...

Hi all, Given that the question: From what i know , I am not sure how this equation can help me estimate the von-klitzing constant? Or is there another way? Thanks!

Homework Statement I posted a picture of the question https://imgur.com/a/8byywYL Homework Equations P = $$(<\psi_{n}|\psi_{o}>)^2$$ The Attempt at a Solution I am guessing that I compute(denote by ##\psi_{o}## the ground state of the old well and by ##\psi_{n}## the ground state of the new...

Homework Statement Consider a system of two quantum particles. Each particle has two quantum states, one with zero energy and one with energy ε>0. For each of the three cases, draw a table of the possible microstates α of the system, and find the canonical partition function Z(β). a)The two...

So the Hawking radiation and the flinging of matter from the black hole, could this explain where all the matter goes? I am unsure of the theory for the second one, but if matter is broken to its quantum particles then why can't those quantum particles be in the Hawking radiation. Still very...

Hello. My name is Jon rotsler I'm an avid independent researcher when I have the time. I have a huge interest in quantum mechanics I'm also bid on thurmo dynamics and magnetic. But rarely have time to do all the fun things I would like so I'm settling for good discussion and a bouncing around of...

Hi all - forgive me, I'd asked a series of questions in a previous post that was deemed to be circular, but I still didn't obtain a satisfactory answer to the question I was asking. In this post, I'm going to try to be very careful to use terms that are at least less 'misplaced', per se...

I was just wondering if macroscopic things like a book or even a human can travel to another universe, like quantum particles.

How would a physicists expect a perfect relativist quantum particles simulation to look like? Can anyone give a description of its functionality? Let's say for example, someone would program a simulation, composed of a 4D space-time diagram. Within this simulation are a large amount of quantum...

Hi everyone: This concept has bothered me for a while. The concept being that two oppositely charged particles (electron and proton) are attracted to each other, but the electrons go on a orbital trajectory around the nucleus instead of directly "sticking to" the nucleus. The closest I have...

In class I learn that we can get the dispersion relation for particles by using E=hbar*w and p=hbar*k. The calculated phase velocity is w/k = hbar*k/2m, while the group velocity is dw/dk=hbar*k/m. All these make sense to me, except one thing: I always thought that E=hbar*w=hf is only applicable...

This is going to seem like it should be an educational question, and perhaps it should, but please bear with me, because I think that it has theoretical content. A nice quote that I recently heard someplace went something like: "We used to argue about whether electrons [etc] were particles or...

Since particles have their own space i heard they cannot meet. But how about the origin if we see the axes perpendicular ?

The 2 slits experiment can be carried out by firing a single electron at a time and then over time observing the gradual build up of what appear to be interference patterns characteristic of a wave passing through the 2 slits on the screen behind the slits. This is despite the fact that the...

Hi pf. From what I have read, when measured, a particles spin can only be in one direction. So either 100% spinning up or 100% spinning down and not in between. So, you can't have a spin that is in between (tilted) - it must be one or the other. But I recently learned that when we place a...

Question: "Write the quantum state for the following system of particles distributed over evenly spaced energy levels" The diagram (couldn't upload so hope its not too rough): 5 ---------------------- 4 ---------------------- 3 --------------X------- 2 ------X---X------X---- 1...

Does all types of quantum particles exist all time? If so where are charm and strange, top and bottom quarks located in an atom?

Is double slit experiment the only proof for quantum particles' superposition??

If we put a quantum particle in it's ground state in a cylinder with a movable piston there is an outward force on the piston? If we now put a quantum particle in the universe is there an outward force on space time however small? Thanks for any help!

Consider this experiment... A satellite is put into orbit around Mars and the date of the experiment is set for when Mars is directly opposite the sun from earth. This puts it about 21 light minutes away from earth. Assuming there are no aliens watching it is absolutely impossible for any...

A wave packet carries information such that when an observation is made, what is received is information, that reveals spin or position etc. All 'particles' at the quantum level can be described by wave packets and the states of those wave packets could be represented by information. The true...

It seems to me there is a problem with special relativity - at least involving a particle which is commonly used as evidence to support it! Am I missing something? Here it is: A spaceship is stationary in space next to the moon. An interstellar muon traveling near the speed of light passes...

So why is it that if you have a system with two distinguisable particles why is their state vector written as |psi>=|psi_1>|psi_2> what's this product? Is this product still "in" the original hilbert space? Kevin

Does anybody in this forum play chess? Or have an idea of how computer chess programs work? Even the very best of them, and lately they have gotten very, very good, work more or less the same way, and always have. In those algorithms, after the move generators and transposition tables and...
