Quantum mechanics boldly points at several contradictions from many references. First the atom wave duality experiment gives us reference that there is no reality, the inhibitions of accuracy, and the endless debate on causality or predetermined universe. Is anyone still currently studing this field and why?

Yep people are still studying it, why because it is very interesting, and can lead to real world solutions to problems such as quantum encryption and entanglement.

QM is the basis for much of atomic and nuclear physics. Any legitimate degree in physics is going to involve at least one class in QM. So yes, it's studied. "Because that's how nature appears to behave" is why.

you can't just through it out because it is counterintuitive. much of sr is counterintuitive, but it is still used.

how active is the field of quantum physics

well, your television uses basic qm. radios, ect.

Quantum Mechanics is not studied much anymore, basically because it is incomplete. Quantum Field Theory (where the fields themseleves are also quantised) on the other hand is very widely studied.

I don't think QM is incomplete. It's our interpretation of QM which is either wrong or incomplete. QM has been highly successful. It gave us lasers, superconductivity, zero point energy, particle physics etc...

This does not make sense to me. QM is not some 'real thing' waiting to be discovered, digested and understood. QM is our interpretation of observations. You have perpetrated a tautology. Shame on you.

QM is a description of one particle states. To allow particle pair production you need QFT.

True, all physical theories are our interpretation of nature.

The problem is with Schroedinger's equation. It is not relativistic, reducing to Newtonian mechanics rather than relativistic mechanics in the correspondence limit.

Severian can you go into this slightly? I've never studied QFT but i have studied QM analysis of hydrogen.

 

Thank you
