Understanding Quantum Spin: A Layman's Guide to Particle Spin …
2012年2月9日 · Quantum spin is related to the concept of superposition in that particles with a spin of 1/2 can exist in multiple spin states at the same time. This is known as superposition, and it is an essential aspect of quantum mechanics that allows for the strange and counterintuitive behavior of particles at the subatomic level.
Quantum Spin - If It’s Not Spinning, What Is It Doing? - Physics …
2021年11月5日 · Quantum spin is one of several quantum properties that particles possess, along with properties like charge and mass. These properties are all interconnected and can affect each other, making quantum spin an important factor in understanding the behavior of particles at the subatomic level.
What does spin quantum number mean? - Physics Forums
2018年11月21日 · What is the spin quantum number? The spin quantum number is a quantum number that describes the intrinsic angular momentum of a particle. It is represented by the symbol "s" and can have only two possible values: +1/2 or -1/2. How does the spin quantum number relate to spin? The spin quantum number is directly related to the concept of spin ...
Quantum Spin vs Spin - Understand the Difference - Physics Forums
2014年1月21日 · Quantum spin and spin are two terms that are often used interchangeably, but they actually refer to different physical phenomena. Spin refers to the intrinsic angular momentum of a particle, while quantum spin refers to the quantized values that spin can take on in …
Does the electron really spin 720 degrees? - Physics Forums
2016年10月4日 · What comes closest to this intrinsic quantum number in classical physics is a classical point particle with some dipole (e.g., a magnetic dipole, and even in the quantum theoretical generalization you have magnetic dipole moments associated with the spin of elementary particles).
Can you change a quantum particle's spin? - Physics Forums
2016年11月27日 · For a spin-1/2 particle (where here "1/2" refers to the magnitude of the spin only) like an electron, its spin state can be thought of as an arrow pointing in a particular direction; the probability of measuring +1/2 when we measure the electron's spin about a particular axis is then ##\cos \theta##, where ##\theta## is the angle between the ...
Quantum entanglement. -- Spin up, spin down, isn't it the same?
2021年4月26日 · What is meant by "spin up" and "spin down" in quantum entanglement? In quantum mechanics, spin refers to an intrinsic property of particles that can have two possible states: "up" or "down". In quantum entanglement, this spin state is used to describe the correlation between two particles.
Quantum spin, wavelength and frequency - Physics Forums
2021年8月31日 · FAQ: Quantum spin, wavelength and frequency What is quantum spin and how does it differ from classical spin? Quantum spin is an intrinsic property of subatomic particles, such as electrons, that determines their angular momentum. Unlike classical spin, which can take on any value, quantum spin is quantized and can only have discrete values.
Difference between "Spin" and "Angular Momentum"? - Physics …
2015年6月29日 · Spin is one of the identities of a particle, just like rest mass. One can't say two different particles as having equal spin angular momentum quantum numbers, if the spins are different then so are the particles. Orbital angular momentum is a kinetical quantity of a moving body, it can always be related to the change of spatial degree of freedom.
Spin Quantum Number: Why is it Always + or - 1/2? - Physics …
2009年8月7日 · This includes the spin quantum number, meaning that two particles with the same spin cannot occupy the same quantum state. Therefore, the spin quantum number helps to determine the allowed states for a particle and plays a crucial role in understanding the behavior of matter. What is the significance of the spin quantum number? The spin quantum ...
