... 1. Is the world local or nonlocal? What is nonlocality? 2. If nonlocal, i.e., superluminal, influences exist, then why can’t they be used for superluminal signalling and communication? 3. How is the role of the scientific observer/agent to be accounted for in realistic approaches to quantum theory? ...

Gravity - Duke Physics
... That is, if the gravitation force on a particle of mass m at a particular place is Fg , then the gravitational field at that place is given by g = Fg /m . Conversely, if the field g is known at a point in space, and if a particle of mass m is placed there, then it will experience a gravitational for ...

Lecture 21: Mean Field Theory of Ferromagnetism
... When we use the term ”magnetic interactions” we mean the dependence of the energy of two or more magnetic moments on their relative orientation. The main cause of ferromagnetism is the so-called exchange interaction or exchange energy, which is due to: i) Coulomb interaction between electrons; ii) P ...

Analytical method for determining quantum well exciton properties in
... Bohr radius equation (7). At the same time, inclusion of these terms in above energy formula does not lead to significant complication of the calculation. The change of the exciton size influences also the exciton transition dipole moment and consequently the optical exciton creation rates. In the c ...

Microcanonical Ensemble
... I haven’t told you how to answer this question; it’s harder. The formula above is the answer to a more restricted question. We’ve assumed here that we have picked a basis of the Hilbert space labelled by the quantum number k, and we know that the state is one of these basis vectors. The answer to th ...

Superconducting Circuits and Quantum Computation
... Superconductive quantum circuits (SQCs) comprising mesoscopic Josephson junctions quantized flux and/or charge states are analogous to the quantized internal levels of an atom. This SQC-atom analogy can be extended to the quantum optical effects associated with atoms, such as electromagnetically ind ...

... Note that the first absorption corresponds to the ground state to first excited state transition and occurs at 2B/h. Typically, however, it may be rather hard to decide exactly what line in a spectrum corresponds to the 0→1 transition. A much better way to determine 2B/h is to notice that the separa ...
