This course introduces the quantum mechanical concept of angular momentum operator and its relationship with rotation operator. It then presents the angular momentum operators, their eigenvalues and ...

A unique propagation phenomenon of acoustic waves has been discovered, paving the way for developing advanced communication ...

The orbital angular momentum operator is defined and its commutation relations with the position and momentum operators, and generally with vector operators, are obtained; the relationship between the ...

In the case of a qubit, quantum information relating to the 0 or 1 states of a classical computer can be encoded on the "'spin up"' and "'spin down"' states of an atom — spin being the intrinsic ...

Quantum Spin Chains: A model in quantum mechanics where spins (quantum angular momentum) are arranged in a one-dimensional chain, allowing for the study of quantum interactions and entanglement.

A group of physicists has claimed that a key motivation for the many worlds interpretation of quantum mechanics is unnecessary. They seem to think that the many worlds interp ...

Surprisingly, they uncovered quantum coherence—features such ... involving photon-number-resolving detection and orbital angular momentum (OAM) measurements, the researchers projected a ...
