In quantum mechanics, the Schrödinger equation describes how a system changes with time. It does this by relating changes in the state of the system to the energy in the system (given by an operator called the Hamiltonian). Therefore, once the Hamiltonian is known, the time dynamics are in principle known.
Sociobiology is a field of biology that aims to explain social behavior in terms of evolution.It draws from disciplines including psychology, ethology, anthropology, evolution, zoology, archaeology, and population genetics.
This article lists the companies worldwide engaged in the development of quantum computing, quantum communication and quantum sensing.Quantum computing and communication are two sub-fields of quantum information science, which describes and theorizes information science in terms of quantum physics.
In physics, a quantum mirage is a peculiar result in quantum chaos. Every system of quantum dynamical billiards will exhibit an effect called scarring, where the quantum probability density shows traces of the paths a classical billiard ball would take. For an elliptical arena, the scarring is particularly pronounced at the foci, as this is the ...
Soon, it became apparent that a new theory must be created in order to make sense of these absurdities, and the theory of quantum mechanics was born. [2] Quantum mechanics was formulated by Schrödinger using wave mechanics and Heisenberg using matrix mechanics. [17] The equivalence of these methods was proven later. [18]
Poincaré made many contributions to different fields of pure and applied mathematics such as: celestial mechanics, fluid mechanics, optics, electricity, telegraphy, capillarity, elasticity, thermodynamics, potential theory, quantum theory, theory of relativity and physical cosmology.
In quantum mechanics, the Hamiltonian of a system is an operator corresponding to the total energy of that system, including both kinetic energy and potential energy.Its spectrum, the system's energy spectrum or its set of energy eigenvalues, is the set of possible outcomes obtainable from a measurement of the system's total energy.
A depiction of the cGh cube. Quantum gravity (QG) is a field of theoretical physics that seeks to describe gravity according to the principles of quantum mechanics.It deals with environments in which neither gravitational nor quantum effects can be ignored, [1] such as in the vicinity of black holes or similar compact astrophysical objects, such as neutron stars, [2] as well as in the early ...
