Textbooks often introduce the quantum harmonic oscillator with the example of a mass on a spring, giving the Hamiltonian
$$H = \frac{1}{2} k x^2 + \frac{1}{2m}p^2 \qquad [x,p] = i \hbar \, .$$
The raising/lowering operators are then introduced as
$$a = \sqrt{\frac{m \omega_0}{2 \hbar}} \left( x +...

In particle physics, quantum field theory in curved spacetime is an extension of standard, Minkowski space quantum field theory to curved spacetime. A general prediction of this theory is that particles can be created by time-dependent gravitational fields (multigraviton pair production), or by time-independent gravitational fields that contain horizons.

Interesting new phenomena occur; owing to the equivalence principle the quantization procedure locally resembles that of normal coordinates where the affine connection at the origin is set to zero and a nonzero Riemann tensor...
Entropic gravity, also known as emergent gravity, is a theory in modern physics that describes gravity as an entropic force—a force with macro-scale homogeneity but which is subject to quantum-level disorder—and not a fundamental interaction. The theory, based on string theory, black hole physics, and quantum information theory, describes gravity as an emergent phenomenon that springs from the quantum entanglement of small bits of spacetime information. As such, entropic gravity is said to abide by the second law of thermodynamics under which the entropy of a physical system tends to increase over...
Modern searches for Lorentz violation are scientific studies that look for deviations from Lorentz invariance or symmetry, a set of fundamental frameworks that underpin modern science and fundamental physics in particular. These studies try to determine whether violations or exceptions might exist for well-known physical laws such as special relativity and CPT symmetry, as predicted by some variations of quantum gravity, string theory, and some alternatives to general relativity.
Lorentz violations concern the fundamental predictions of special relativity, such as the principle of relativity, the...
Christian communism is a form of religious communism based on Christianity. It is a theological and political theory based upon the view that the teachings of Jesus Christ compel Christians to support communism as the ideal social system. Although there is no universal agreement on the exact date when Christian communism was founded, many Christian communists assert that evidence from the Bible suggests that the first Christians, including the Apostles, established their own small communist society in the years following Jesus' death and resurrection. As such, many advocates of Christian communism...
I have taken my first course on quantum mechanics, in order to get ready for the Monday test, I am trying to solve the previous year test.
One of the points is as in the title, I am going to present my answer and I want to know, whether it is correct and complete.
Moreover I would like to read ...
