Vor 3 Stunden · At zero temperature, when we have a partially filled band, the highest occupied energy level within the band is the Fermi level \(\epsilon_F\). The value of \(\epsilon_F\) can be calculated from (\ref{8.4.3}), knowing \(\bar{n}\), the number of electrons (not bound to sites); this is shown in Table 8.4.1. Since \(1\;eV\) is of the order \(10^4\;K\) in terms of temperature, we see that, for ...
Vor 11 Stunden · Newton's laws of motion are three physical laws that describe the relationship between the motion of an object and the forces acting on it. These laws, which provide the basis for Newtonian mechanics, can be paraphrased as follows: A body remains at rest, or in motion at a constant speed in a straight line, except insofar as it is acted upon by ...
Vor 10 Stunden · 9.7.2 Equations relating kinematics in rotating and fixed CS. With the following equations one can determine the velocity and acceleration vector of a point mass \(B\) as measured by the observer \(O\) if its velocity and acceleration as measured by the captain in the rotating and translating ship \(S\) are known:
Vor 11 Stunden · Theorem 10 implies that all those varieties \(\in {\mathscr {V}}_L\) defined over a global field L, which universally satisfy the Hasse principle, i.e., those also satisfy the Hasse principle over any finite extension of L, also satisfy the Hasse principle in both senses over any algebraic extension k of L.

Vor 11 Stunden · ePrint Report: Traceable Secret Sharing Based on the Chinese Remainder Theorem Charlotte Hoffmann . Traceable threshold secret sharing schemes, introduced by Goyal, Song and Srinivasan (CRYPTO'21), allow to provably trace leaked shares to the parties that leaked them. The authors give the first definition and construction of traceable secret ...
Vor 11 Stunden · Students often ask what the point of the formula is. You could ask the same about the Pythagorean theorem. But as you’ll see when we derive the arclength below, without Pythagoras is would be impossible for us to have discovered how to calculate the length of a given curve or arc.
