0a041aa2ed32d84c | My problem involves the solution of a second-order ODE with a fixed-step (input and output). Specifically, this ODE is the radial part of Dirac and Schrödinger equation for a spherical symmetric potential.
This is for example the ODE of the radial part Schrödinger equation:
$$\left(\frac{d^2}{dr^2} +2r\frac{d}{dr} -\... |
0b095f33a0a5cf57 | When developing algorithms in quantum computing, I've noticed that there are two primary models in which this is done. Some algorithms - such as for the Hamiltonian NAND tree problem (Farhi, Goldstone, Guttman) - work by designing a Hamiltonian and some initial state, and then letting the system evolve according to the... |

Jump to: navigation, search
A Bose–Einstein condensate (BEC) is a state of matter of bosons confined in an external potential and cooled to temperatures very near to absolute zero (0 K or −273.15 °C). Under such supercooled conditions, a large fraction of the atoms collapse into the lowest qu... |
1c4eb53cd057eec4 | Cutting-Edge Computational Chemistry Enabled by Deep Learning
Machine learning is becoming a bigger part of chemistry as of the last two or three years. Industries need to have people trained in both fields, and it’s taken time for them to make their way into this sector. Olexandr Isayev is at the forefront of that wa... |
77e40f56bd3c287c | If an EM wave only gives us a probability of where a photon may be at a given moment, and the HUP tells us that we can't know the exact location of the photon. Then would it be correct to say that a photon does not travel in a straight line?
If this is true, wouldn't the photon's crooked path mean that it must travel ... |

Atomic Theory III: Wave-Particle Duality and the Electron
by Adrian Dingle, B.Sc., Anthony Carpi, Ph.D.
As discussed in our Atomic Theory II module, at the end of 1913 Niels Bohr facilitated the leap to a new paradigm of atomic theoryquantum mechanics. Bohr’s new idea that electrons could... |

Most textbooks explain quantum mechanics as a story where each step follows naturally from the one preceding it. However, the development of quantum mechanics was exactly the opposite. It was a zigzag route, full of pe... |
27aa6a48853cf70f | As is well-known, the Maxwell equations can be phrased vectorially as,
\begin{align} \nabla \cdot \mathbf E &= \frac{\rho_f}{\varepsilon}, &\text{Gauss's law,}\\\ \nabla \cdot \mathbf B &= 0, &\text{No-name law (no monopoles),}\\\ \nabla \times \mathbf E &= - \partial_t \mathbf B, &\text{Faraday's law,}\\\ \nabla \tim... |
