Quantum Entanglement

Image
Quantum Entanglement Annihilation is the condition in which matter and antimatter gets collide together and produce energy. When electron and positron collides it produces two photons which are entangled. Means one photon is in "up" state whereas another will be in "down" state when we measure any one of the photon. But if we don't measure then photons are in both state "up" and "down" simultaneously. If one photon is kept one side of the universe and another in another side of the universe measuring one state of photon can affect another photon at the same time. If we find one photon is in "up" state at the same time another will be in "down" state. This phenomenon is called Quantum Entanglement. Equation for Quantum Entanglement I cannot decide which state to collapse the composite system into, and therefore cannot transmit information to Bob by acting on her system. Causality is thus preserved, in this parti...

Fermions in Particle Physics -(Pauli Exclusion Principle) #Physik_World

Image
Fermions: Fermions are those particles which includes  quarks and leptons. Quarks and leptons are spin -1/2  particles, implying that they are fermions according to the spin-statistics theorem . Fermions follows Fermi-Dirac statistics. These particles obey the Pauli exclusion principle. The Pauli exclusion principle is the quantum mechanical principle which states that two or more identical fermions (particle with half integer spin) cannot occupy the same quantum state within a quantum system simultaneously. In the case of electrons in atoms, it can be stated as follows: n, the principle quantum number, l, the angular momentum, m l , themagnetic quantum number and m s, the spin quantum number. For example, if two electron reside in the same orbital, and if their n, l and  m l value are same, then their  m s  must be different and thus the electrons must have opposite half-integer spin projection of 1/2 and -1/2. (Spin Up and Down) ...

Gauge Bosons Or Vector Bosons

Image
Gauge Bosons Or Vector Bosons (Force Carrier): In particle physics, a vector boson is a boson with the spin equals to 1.  Gauge Bosons includes: The photon of electromagnetism. The W and Z bosons of the weak interaction. The gluon of the strong interaction. All known gauge bosons includes spin 1. Therefore, all known gauge bosons are vector bosons.  Gauge bosons are different from other kinds of bosons : Fundamental scalar bosons (the higgs bosons), mesons, larger composite non-force-carrying bosons, such as certain atoms.
