Find the sum of the measures of the interior angles of each convex
Find the sum of the measures of the interior angles of each convex

... angles are congruent. Thus, the alternate interior angles at top and bottom must both have a measure of 4y as shown . Since the opposite sides of the parallelogram are parallel, the consecutive interior angles must be supplementary. So, set the sum of 42, 23, 4y, and 83 equal to 180 and solve for y. ...

... concept for understanding exotic phenomena in many different systems18–23. A natural question to ask is whether MFs can also exist in an FF or LO superconductor or superfluid? In this article, we propose that FF superconductors/superfluids may support MFs if they possess two crucial elements: gapped b ...

The well-established, empirically well-confirmed precursor theories – General Relativity and Quantum Mechanics –, together with the already existing empirical data that confirmed these theories, are still the only concrete elements that constitute a reasonable starting point for the different attemp ...

... that we look at. For example, in an optical absorption experiment, we apply light (the external perturbation) and we look at the light that comes back from the system (the response). In this particular case both correspond to the same type of perturbation, but this does not have to be the case, we m ...

Lectures on Quantum Mechanics (nonlinear PDE point of view)

... These lectures correspond to a three-semester course given by the author at the Faculty of Mathematics of the Vienna University in the academic years 2002/2003 and 2003/2004. We expose well known Schrödinger quantum mechanics with traditional applications to Hydrogen atom, but the form of the expos ...

... However, after averaging over the whole phase space, we find that the fidelity decay can be well fitted by an inverse power law 1 / t, as shown in Fig. 4. In this case, for the quantum evolution of initial coherent state BEC, high fidelity can be expected, because the fidelity has a slow power-law d ...

... exercises an action, or inversely, within which it can be acted upon, is restricted to a cube of side one millionth of a centimeter. This is a very small volume indeed, and one of the problems that we are confronted with is that we lose all intuitive feeling on such small scales. To understand fully ...

Gravitational interaction would bring in Planck length as a basic scale in this manner. P T in turn would define the twistor space in which the twistorial lifts of im ...

... A theorem in the algebraic setting Suppose that we do require B 6= C for the definedness of Circle3(A, B, C). Then: Theorem (with Freek Wiedijk) Circle3 is not definable from the other operations. Proof. Let t be a term definable without Circle3, with one free point variable x. Then t becomes undefi ...

As the magnetic field rotates more and more slowly, the time-energy uncertainty, proportional to the length of the quantum trajectory, calculated by the exact solution is entirely different from the one obtained by the adiabatic ...

According to the main result of the Lagrangian formulation of classical mechanics, solutions of Newton’s differential equation (2.2) correspond essentially to critical points of the action functional S. However, we need boundary conditions to obtain the correct statement (without them, the functiona ...

... 2. Motivation: a critical view • The big picture – In QC the circuits are prone to frequent failures – Safe recovery is a problem – A successful FTAM (for our error model – single random fault) means that, for a x fault rate, the overall circuit error rate is x 2 – Besides coding, structural redunda ...

The total length of the 1D optical lattice is chosen as N = 100, which is long enough to ensure that the coupling between two ends is vanishingly small (10−7 t). An ...

Instanton

An instanton (or pseudoparticle) is a notion appearing in theoretical and mathematical physics. An instanton is a classical solution to equations of motion with a finite, non-zero action, either in quantum mechanics or in quantum field theory. More precisely, it is a solution to the equations of motion of the classical field theory on a Euclidean spacetime.
