Applications of Quantum Mechanics
Academic Editor: Marek Szopa

Quantum mechanics is one of the most prolific theories of all time. Despite the many con troversies it has aroused since the dawn of its history, its predictions have been confirmed experimentally with incredible accuracy. One of the fields that uses the quantum mechan ics formalism is quantum economics - a very promising novel field of its application. The impetus for the development of this field was the emergence of programmable quantum computers. The various areas of quantum economics research include: quantum game theory, market games, duopoly problems, auctions and competitions, gambling, quantum money, quantum annealing, quantum cryptography and security issues quantum optimal transport, high-frequency trading or quantum probability amplitude in quantum statistics.

Definition: Two-dimensional (2D) materials are generally defined as crystalline substances with a few atoms thickness.Two-dimensional transition metal dichalcogenide (2D-TMDs) semiconducting (SC) materials have exhibited unique optical and electrical properties. The layered configuration of the 2D-TMDs materials is at the origin of their strong interaction with light and the relatively high mobility of their charge carriers, which in turn prompted their use in many optoelectronic applications, such as ultra-thin field-effect transistors, photo-detectors, light emitting diode, and solar-cells. Generally, 2D-TMDs form a family of graphite-like layered thin semiconducting structures with the chemical formula of MX2, where M refers to a transition metal atom (Mo, W, etc.) and X is a chalcogen atom (Se, S, etc.). The layered nature of this class of 2D materials induces a strong anisotropy in their electrical, chemical, mechanical, and thermal properties. In particular, molybdenum disulfide (MoS2) is the most studied layered 2D-TMD.
