Quantum mechanics physics

According to Wikipedia, there's an infinite set of possible wavefunctions (orbitals) for the hydrogen atom: $$\psi_{n\ell m}(r,\theta,\phi) = \sqrt {{\left ( \frac{2}{n a_0} \right )}^3\frac{(n-\e...

THE QUANTUM SOURCE OF SPACE TIME Background. We recently published a news story on how quantum entanglement can be used to bridge the theoretical gap between quantum mechanics and general relativity,...

A particle is trapped inside a black hole. What is the probability it will escape via quantum tunneling? To figure this out, we begin by defining the variables involved: The diagram below shows two regions: I and O. Region I is inside the event horizon, within the Schwarzshild radius (rs). Region O is outside the event horizon. The question we ask is what is the probability the particle (red dot) will reach region O? And, we could also ask what is the probability the particle will fail to…

Dr Victoria Porozova | Theoretical physicist on Instagram: "What’s the difference between Quantum and Classical mechanics? It is going to be a list and intersections between both. Moreover an atom can be in some cases be described by classical (Newton’s laws) or quantum mechanics (Schrödinger equation, Density matrix formalism). About these things we will talk in further videos. For now let’s start with the notion of trajectory. The main difference is that in classical mechanics you can…

Learn what quantum physics is all about, with elegant and clear cartoon drawings that help you visualize the most important aspects of quantum physics.

Quantum mechanics can be challenging to comprehend due to its foundation on postulates about wave functions that are hard to relate to. Furthermore, quantum particles do not adhere to classical laws, making it challenging to predict their behavior.

We identify an experimental method which could finally reveal whether objects much larger than atoms - such as humans or animals - can exist in several places at once.
