The video of an experiment showing vacuum fluctuations (in the red ring) amplified by spontaneous parametric down-conversion.. If the quantum field theory can be accurately described through perturbation theory, then the properties of the vacuum are analogous to the properties of the ground state of a quantum mechanical harmonic oscillator, or more accurately, the ground state of a measurement ...
The book has also been suggested as a complement to simplified introductory books in quantum mechanics. [ 3 ] Experimental physicist and 2022 Nobel laureate in Physics Alain Aspect , has frequently mentioned that the book was a revelation early in his career, helping him better understand the research papers of quantum mechanics and the work of ...
3D visualization of quantum fluctuations of the quantum chromodynamics (QCD) vacuum [1]. In quantum physics, a quantum fluctuation (also known as a vacuum state fluctuation or vacuum fluctuation) is the temporary random change in the amount of energy in a point in space, [2] as prescribed by Werner Heisenberg's uncertainty principle.
Quantum mechanics is a fundamental theory that describes the behavior of nature at and below the scale of atoms. [2]: 1.1 It is the foundation of all quantum physics, which includes quantum chemistry, quantum field theory, quantum technology, and quantum information science. Quantum mechanics can describe many systems that classical physics cannot.
In the context of quantum mechanics, the Void is no longer seen as a simple vacuum but as a quantum vacuum—a field filled with fluctuating energy. As Lawrence Krauss describes it in A Universe from Nothing (2012), even "empty" space is not truly empty but contains a seething field of virtual particles that continuously pop in and out of ...

Quantum mechanics can be used to describe spacetime as being non-empty at extremely small scales, fluctuating and generating particle pairs that appear and disappear incredibly quickly. It has been suggested by some such as Paul Dirac [ 13 ] that this quantum vacuum may be the equivalent in modern physics of a particulate aether.
Videos for all of these courses are available online. In addition, Susskind has made available video lectures over a range of supplement subject areas including: advanced quantum mechanics, the Higgs boson, quantum entanglement, string theory, and black holes. The full series delivers over 100 lectures amounting to something on the order of 200 ...
