We discuss the particle method in quantum mechanics which provides an exact scheme to calculate the time-dependent wavefunction from a single-valued continuum of trajectories where two spacetime points are linked by at most a single orbit. A natural language for the theory is offered by the hydrod...
IN a recent re-examination 1 of the foundations of quantum mechanics, Dirac asserts, inter alia , that the Heisenberg and Schroedinger pictures in quantum electrodynamics are not equivalent because the unitary operator which connects both pictures, namely e iHt/h , where H = H Dirac field + H...
We propose a new systematic fibre bundle formulation of nonrelativistic quantum mechanics. The new form of the theory is equivalent to the usual one and is in harmony with the modern trends in theoretical physics and potentially admits new generalizations in different directions. In it the Hilbert ...
Albert Einstein(March 14, 1879 - April 18, 1955) was a theoretical physicist who is widely regarded as the greatest scientist of the 20th century. He proposed the theory of relativity and also made major contributions to the development of quantum mechanics, statistical mechanics, and cosmology....
Considered a very interesting problem in the formal structure of quantum mechanics, the Caldirola–Kanai oscillator deserves particular attention. For instance, it has been studied in terms of the quantum Arnold transformation [26,58], where exact solutions have been provided for the related ...
