1. If you want to do research in theoretical physics, you have to be very strong in math (abstract math). Otherwise, if your goal is to understand what's going on in quantum physics, field theory etc, then you will not need any math beyond Boas' mathematical methods. Share. Cite.

Quantum Physics: A First Encounter: Interference, Entanglement, and Reality; Six Quantum Pieces: A First Course in Quantum Physics. All three books are modern: instead of stressing (otherwise free) particle(s) in a box and the Bohr's atom, they emphasize one particle interference, entanglement, local realism, quantum teleportation.

But in quantum physics, usually even for simple problems I can get stuck or don't know where to start. I want to rebuild my knowledge from a new source. The literature I've used so far is: Introduction to Quantum Mechanics by David J.Griffiths, Quantum physics by Leonard Schiff, Modern Quantum Mechanics (Revised Edition) by J.J.Sakurai.

a quantum state ρ ρ, which is a mathematical object describing the quantum system at a given time 1 1. Given these two ingredients one can compute the probability p(λ|ρ, A) p (λ | ρ, A) that the measurement of A A on a system in state ρ ρ yields the outcome λ λ. The recipe for computing p(λ|ρ, A) p (λ | ρ, A) is known as the Born ...

Improve this question. asked Aug 16, 2015 at 2:03. Lynn. 271 1 2 4. Are you talking quantum field theory where there are operator valued fields defined in space and locality is about operators determined by spacelike separated regions commuting. Or nonrelativistic quantum mechanics where the wavefunction is not defined on space (it is defined ...

Speculations on quantum gravity are in fact the darling of many popular programs and ideas about physics. But because the original theory of general relativity by a fellow named Einstein was a purely geometric theory without a shred of quantum anything to it, it remains to this day a theory that is difficult to fold into the kind of pure ...

Using quantum field theory allows us to calculate the behaviour of electrons whether they happen to be involved in particle-like or wave-like interactions. This doesn't mean that the electron is a quantum field, and we'll almost certainly replace quantum field theory by some even more complicated e.g. some future development of string theory.

Quantum physics is generally accepted as the more correct version of physics compared to classical physics. That is, classical physics is mostly wrong. However, classical physics is usually correct enough that, for most everyday applications, you wouldn't notice the difference between the quantum and classical results.

These are sinusoidal functions which means they not only have an amplitude ( a measure) but also a phase. Coherence means that the phases of the wave function are kept constant between the coherent particles. Coherence also exists in classical dimensions wherever there are sinusoidal functions describing the situation.
