Condensed matter physics is the field of physics that deals with the macroscopic and microscopic physical properties of matter, especially the solid and liquid phases, that arise from electromagnetic forces between atoms and electrons. More generally, the subject deals with condensed phases of matter: systems of many constituents with strong ...
Atomic physics is the subfield of AMO that studies atoms as an isolated system of electrons and an atomic nucleus, while molecular physics is the study of the physical properties of molecules. The term atomic physics is often associated with nuclear power and nuclear bombs, due to the synonymous use of atomic and nuclear in standard English.
Properties may also be classified with respect to the directionality of their nature. For example, isotropic properties do not change with the direction of observation, and anisotropic properties do have spatial variance. It may be difficult to determine whether a given property is a material property or not.
Such states of matter are studied in high-energy physics. In the 20th century, increased understanding of the properties of matter resulted in the identification of many states of matter. This list includes some notable examples.
[8] The book, along with Kittel is also used as a benchmark for other books on solid-state physics; the publisher's description for the book Advanced Solid State Physics by Philip Phillips that was supplied to the Library of Congress for its bibliography entry states: "This is a modern book in solid state physics that should be accessible to ...
The Fermi liquid is qualitatively analogous to the non-interacting Fermi gas, in the following sense: The system's dynamics and thermodynamics at low excitation energies and temperatures may be described by substituting the non-interacting fermions with interacting quasiparticles, each of which carries the same spin, charge and momentum as the original particles.
Quantum materials is a label that has come to signify the area of condensed-matter physics formerly known as strongly correlated electronic systems. Although the field is broad, a unifying theme is the discovery and investigation of materials whose electronic properties cannot be understood with concepts from contemporary condensed-matter ...
A quantum critical point is a point in the phase diagram of a material where a continuous phase transition takes place at absolute zero.A quantum critical point is typically achieved by a continuous suppression of a nonzero temperature phase transition to zero temperature by the application of a pressure, field, or through doping.
