The Aharonov–Bohm effect , sometimes called the Ehrenberg–Siday–Aharonov–Bohm effect, is a quantum mechanical phenomenon in which an electrically charged particle is affected by an electromagnetic field ( E , B ), despite being confined to a region in which both the magnetic field B and electric field E are zero. The underlying mechanism is the coupling of the electromagnetic potential with the complex phase of a charged particle's wavefunction , and the Aharonov–Bohm effect is accordingly illustrated by interference experiments . The most commonly described case, sometimes called the Aharonov–Bohm solenoid effect , takes place when the wave function of a charged particle passing around a long solenoid experiences a phase shift as a result of the enclosed magnetic field, despite the magnetic field being negligible in the region through which the particle passes and the particle's wavefunction being negligible inside the solenoid.

The Franck–Hertz experiment was a physics experiment that provided support for the Bohr model of the atom , a precursor to quantum mechanics .
The quantum Zeno effect is a name coined by George Sudarshan and Baidyanath Misra of the University of Texas in 1977 in their analysis of the situation in which an unstable particle , if observed continuously, will never decay. [ 1 ] One can "freeze" the evolution of the system by measuring it frequently enough in its (known) initial state. The meaning of the term has since expanded, leading to a more technical definition in which time evolution can be suppressed not only by measurement: the quantum Zeno effect is the suppression of unitary time evolution caused by quantum decoherence in quantum systems provided by a variety of sources: measurement, interactions with the environment, stochastic fields, and so on. [ 2 ] As an outgrowth of study of the quantum Zeno effect, it has become clear that applying a series of sufficiently strong and fast pulses with appropriate symmetry can also decouple a system from its decohering environment.

The double-slit experiment, sometimes called Young 's experiment (after Young's interference experiment ), is a demonstration that matter and energy can display characteristics of both waves and particles , and demonstrates the fundamentally probabilistic nature of quantum mechanical phenomena. In the basic version of this experiment, a coherent light source such as a laser beam illuminates a thin plate pierced by two parallel slits, and the light passing through the slits is observed on a screen behind the plate.
As the temperature decreases, the peak of the black-body radiation curve moves to lower intensities and longer wavelengths. The black-body radiation graph is also compared with the classical model of Rayleigh and Jeans.

Important in the field of quantum mechanics , the Stern–Gerlach experiment , [ 1 ] named after German physicists Otto Stern and Walther Gerlach , is a 1922 experiment on the deflection of particles , often used to illustrate basic principles of quantum mechanics. It can be used to demonstrate that electrons and atoms have intrinsically quantum properties, and how measurement in quantum mechanics affects the system being measured.
