Symmetries in quantum mechanics describe features of spacetime and particles which are unchanged under some transformation, in the context of quantum...

represented by a Feynman diagram according to perturbation theory in quantum mechanics. Quantum field theory emerged from the work of generations of theoretical...

notable textbooks on classical mechanics and quantum mechanics arranged according to level and surnames of the authors in alphabetical order. Feynman, Richard...

The many-worlds interpretation (MWI) is an interpretation of quantum mechanics that asserts that the universal wavefunction is objectively real, and that...

thermodynamics predicts the time symmetry to hold. However, quantum noninvasive measurements are predicted to violate time symmetry even in equilibrium, contrary...

Lagrangian retains that symmetry. By definition, spontaneous symmetry breaking requires the existence of physical laws (e.g. quantum mechanics) which are invariant...

mathematical formulations of quantum mechanics are those mathematical formalisms that permit a rigorous description of quantum mechanics. This mathematical formalism...

non-Hermiticity. Parity–time (PT) symmetry was initially studied as a specific system in non-Hermitian quantum mechanics. In 1998, physicist Carl Bender and...

distances, quantum mechanics has a profound effect on physical phenomena. Each theory of quantum gravity uses the term "quantum geometry" in a slightly...

theory. The primary question that quantum chaos seeks to answer is: "What is the relationship between quantum mechanics and classical chaos?" The correspondence...
