PeroK replied to the thread Calculating <r> from <x> with no further calculation.Do you think the expected value of ##x## is positive or negative? I.e. to the right of the atomic nucleas or to the left? -
PeroK replied to the thread Conflicting definitions of linear independence.You are given three vectors, which are linearly independent. If you add a 4th vector, the zero vector, then that extended set of...

PeroK replied to the thread Conflicting definitions of linear independence.What precisely is "underdetermined" in this case?

PeroK reacted to Demystifier's post in the thread I The Extended Wigner's Friend Scenarios with
Informative.
The review https://arxiv.org/abs/2308.16220 argues that, among the many extended Wigner-type thought experiments considered recently... -
PeroK reacted to SergejMaterov's post in the thread I Would gravitons theoretically act like photons? with Informative.
Gravity’s coupling G is dimensionful, so you only get a meaningful gravitational fine‑structure constant once you specify masses or...

But it can, as long as the wave function has non-zero amplitude outside the box. Two consecutive position measurements will in general...

PeroK replied to the thread I Wigner's friend and quantum tunneling.I'm not sure I understand the question. Do you have a reference for the scenario in question?
-
PeroK replied to the thread Calculating <r> from <x> with no further calculation.Well, ##x## is frame dependent. So, I guess you have to know which side of the hydrogen atom is left and right.

Is Griffiths your first exposure to quantum mechanics? If so, you might consider working through the chapters on modern physics in an...

PeroK replied to the thread I Shape of wave function (probability distribution) of a single photon.Dirac's equation is for the electron. You need QED (Quantum Electrodynamics) for light. Feynman wrote a book on this...
