Single-photon decision maker
... In this study, we report decision making based on single photons. One of the most significant attributes of single photons is literally its particle and yet probabilistic nature. For example, consider a single photon that impinges on a beam splitter. The probability of observing the single photon in ...

Path Integral Formulation of Quantum Mechanics
... In (2.13) L(~r, ~r˙ , t) is the Lagrangian of the classical particle. However, in complete distinction from Classical Mechanics, expressions (2.12, 2.13) are built on action integrals for all possible paths, not only for the classical path. Situations which are well described classically will be dis ...

... The coaction of Mq on the generators of Ω(Aq ) is given by equation (1.1). In principle, the theorem can be verified directly from the definitions. But that is not a good approach because it does not tell us how to construct Ω(Aq ) and Mq in the first place. We now address this question. 1.7. Method ...

Also, the complex multibody interaction between the two rare gas atoms is simplified in three two-body problems: the interactions between the active electron (3p) and each of the two cores, Ne+ (2p5 ) and He(1s2 ), at which the core–core interaction is added.
