Magnetic-Flux-Controlled Giant Fano Factor for Coherent Tunneling Through a Parallel Double-Quantum-Dot 平行双量子点连贯渠道量子学物理研究我们由采用解决数字的量率方程通过联合平行的量点干涉仪在通道报导我们零频率的射击噪音的研究.我们证明在二条小径和强壮的库仑排斥之间的量干扰效果的联合能导致一个巨大的 ...
A new approach to perform high-pressure NMR at unprecedented pressures is introduced. A new pathway to nuclear magnetic resonance (NMR) spectroscopy for picoliter-sized samples (including those kept in harsh and extreme environments, particularly in diamond anvil cells) is introduced, using inductively...
Explain. Suppose the magnetic flux through a coil of wire varies with time, as shown in the diagram. Using the same timescale, sketch a graph showing how the induced voltage varies with time. Where does the induced voltage have its largest...
aDifferent values of magnetic flux lead to different values of core reluctance. These values can be easily computed through the use the magnetic material B-H curve. 磁性焊剂的不同的价值导致核心勉强的不同的价值。 这些价值可以通过用途容易地被计算磁性材料B-H曲线。[translate]...
magnets. The reading of the flux meter is related to the position of the sample in the measuring coil. The calibration of the test coil requires a constant current to test the size of the magnetic field in a zero magnetic field environment, and then the constant of the test coil is ...
We present mass spectrum and magnetic moments of the\(\bar{n}\bar{n}QQ\)states, where\(n=u,d,s\)and\(Q=c,b.\)We solve four-body Schrödinger equation with a quark potential model by using diffusion Monte Carlo (DMC) method. The quark potential is based on the Coulomb, confinemen...
The magnetic flux through the closed-loop leads to a new term in the free energy equality Eq. (4). The symbols and expressions for the propagators K are listed in the legend, where the tilde variables are those for the conjugate process and B is the magnetic field. The expressions for ...
A SQUID is a superconducting loop with two parallel Josephson junctions that can detect incredibly small changes in magnetic flux. The two other components that make up the SQUID magnetometer are a superconducting magnet and a cryostat, which allow field and temperature-dependent susceptibility ...
In general, any current loop has a magnetic field and a corresponding magnetic moment. Similarly, magnetic moments in a magnetized substance may be described as arising from internal currents at the atomic level. There are intrinsic magnetic moments for electrons, protons, neutrons, and other partic...
