"London penetration depth is one of the most fundamental parameters describing superconductors; it basically tells you how robust superconductivity is," said Prozorov. "I've been measuring this quantity using different techniques for most of my research career and NV sensing represents a significant ad...
Why is heat transfer a no equilibrium phenomenon? You are standing with your bag in your hands on that ice in the middle of a pond. The ice is so slippery that it can offer no friction. How can you come out of the ice? If air is a bad conductor of heat, wh...
A new ultrafast laser angle-resolved photoemission spectroscopy (ARPES) technique may soon help scientists realize some of the biggest obstacles to the electronic states of high-temperatures superconductors so that they may one day put these energy-saving metals to practical use. Superconductivity, in...
In physics, the black body emits all the incident radiation on it and re-radiates the energy, which is a characteristic of this type of system only. In this phenomenon of black body radiation, the black body is a perfect absorber for all incid...
There can be “multiple rates of time” in one frame if the frame is non-inertial. This phenomenon is closely related to gravitational time dilation and the equivalence principle. However, it is not likely (in my opinion) to help you learn electromagnetism. I think you have gone far...
phenomenon known as theKondo effect-- which also has its roots in quantummagneticeffects. Based on what they knew of this effect, they created a model of a "Kondo lattice," a fine-grained mesh of electrons that behaved like those that had been observed in Kondo studies of real-world ...
A phenomenon where the sound created by tapping a cup of hot liquid rises in pitch as a soluble powder is added. Perky effect An experiment in which participants were asked to visualize an object while staring at a screen on which the outline of that object was subtly projected. Participants...
Name the material of which it is made. Give two reasons for using that material. Why do substances expand when the temperature is increased? Give the reason(s) for superconductivity at low and at high temperatures. What are the properties of thermal radiation? H...
The refrigeration refers to the amount of heat which is required to extract from a space in order to produce a temperature lower than the surroundings. The device used is known as a refrigerator. It works on the principle of reversed Carnot cycle. The efficiency of a refrigerator is expressed...
Briefly describe the phenomenon of magnetization. What is a magnetic dipole? How is its strength defined? On which pair of particles would a force of attraction occur? Explain. What would you do if you could change one thing about the laws of physics and why? Explain why nucl...
