Special Issue Information

Dear Colleagues.

Quantum mechanics is the most accurate physical theory discovered to date to explain nature. Like any physical theory, quantum mechanics has two interrelated components—mathematical formalism and physical interpretations. The mathematical formalism of quantum mechanics is nothing but the algorithmic structure containing equations and other mathematical concepts, mainly employing a part of functional analysis, especially Hilbert spaces. On the other hand, we need physical interpretations to compare the results predicted by these mathematical models with the experimental observations. Apart from its role as the fundamental physical theory in almost all branches of physics, the present research endeavours focusing on the foundational aspects of quantum mechanics, quantum information theory and quantum computation rely to a large extent on ever-improving mathematical analyses of quantum mechanics along with their physical interpretations. This Special Issue looks for novel developments of mathematical analyses involved in quantum mechanics, including, but not limited to:

  1. Deriving new uncertainty relations;
  2. Mathematical frameworks developing experimental tests of Bell nonlocality;
  3. Fundamental mathematical structure of entanglement theory;
  4. Mathematical development of LOCC distinguishability;
  5. Studying spatial quantum correlations in the context of no-signalling polytope;
  6. Mathematical descriptions of temporal quantum correlations;
  7. Improving the mathematical formalism of generalized quantum measurements and measurement incompatibility;
  8. Quantum channel, CPTP map.

Abstract
We extend the scope of the unified factorization method to the solution of conditionally and unconditionally exactly solvable models of quantum mechanics, proposed in a previous paper [R.R. Nigmatullin, A.A. Khamzin, D. Baleanu, Results in Physics 41 (2022) 105945]. The possibilities of applying [...] Read more.
We extend the scope of the unified factorization method to the solution of conditionally and unconditionally exactly solvable models of quantum mechanics, proposed in a previous paper [R.R. Nigmatullin, A.A. Khamzin, D. Baleanu, Results in Physics 41 (2022) 105945]. The possibilities of applying the unified approach in the factorization method are demonstrated by calculating the energy spectrum of a potential constructed in the form of a second-order polynomial in many of the linearly independent functions. We analyze the solutions in detail when the potential is constructed from two linearly independent functions. We show that in the general case, such kinds of potentials are conditionally exactly solvable. To verify the novel approach, we consider several known potentials. We show that the shape of the energy spectrum is invariant to the number of functions from which the potential is formed and is determined by the type of differential equations that the potential-generating functions obey.
