Light polarisation and photon spin

Click For Summary
The link between light polarization and photon spin is established through the projection of the photon's spin state. A photon with helicity +1 exhibits 100% left circular polarization. This relationship highlights how the intrinsic angular momentum of photons correlates with their polarization characteristics. Understanding this connection is crucial for applications in quantum optics and photonics. The discussion emphasizes the fundamental nature of light's polarization in relation to photon spin.

What is the link between the polarisation of light and photon spin?
 
Physics news on Phys.org
Polarization is related to the projection of the spin of the photon.
 
Light is 100% left circular polarized for a photon with helicity +1.
 
Thank you
 

Thread 'Two equivalent statements of time reversal symmetric Hamiltonian'

Time reversal invariant Hamiltonians must satisfy ##[H,\Theta]=0## where ##\Theta## is time reversal operator. However, in some texts (for example see Many-body Quantum Theory in Condensed Matter Physics an introduction, HENRIK BRUUS and KARSTEN FLENSBERG, Corrected version: 14 January 2016, section 7.1.4) the time reversal invariant condition is introduced as ##H=H^*##. How these two conditions are identical?
