Representation Theory and Topology of Coherent Photons with Angular Momentum
Shinichi Saito
Photons are elementary particles of lights, which have both spin and orbital angular momentum as internal degrees of freedom. Nature of spin is known as polarisation, which is wide…
Photonic Quantum Chromo-Dynamics
Shinichi Saito
Vortexed photons with finite orbital angular momentum have a distinct mode profile with topological charge at the centre of the mode, while propagating in a certain direction. Each…
Macroscopic Singlet, Triplet, and Colour-Charged States of Coherent Photons
Shinichi Saito
A ray of photons, emitted from a laser source, is in a coherent state, where macroscopic number of photons are degenerate in the same quantum state. The coherent state has degrees…
Topological Polarisation States
Shinichi Saito
Polarisation states are described by spin expectation values, known as Stokes parameters, whose trajectories in a rotationally symmetric system form a sphere named after Poincaré.…
Macroscopic Single-Qubit Operation for Coherent Photons
Shinichi Saito
Polarisation is described by an wavefunction due to macroscopic coherence of photons emitted from a ubiquitous laser source, and thus, a laser pulse is expected to behave a…
SU(2) Symmetry of Coherent Photons and Application to Poincaré Rotator
Shinichi Saito
Lie algebra is a hidden mathematical structure behind various quantum systems realised in nature. Here, we consider wavefunctions for polarisation states of coherent photon…
