In materials, a photon quasiparticle isa photon as affected by its interactions with the material. ... A polaron is a quasiparticle which comes about when an electron interacts with the polarization of its surrounding ions. An exciton is an electron and hole bound together. What is electron hol...
Feynman's Polaron Theory: Translation into Hamiltonian Language This is an attempt to translate the Feynman polaron path integral method into the language of a Hamiltonian formalism. The lowest energy and the effective mass expressions of Feynman are exactly reproduced in a Hamiltonian language. But ...
The Kondo effect, one of the few examples in physics where many particles collectively behave as one object (a single quantum-mechanical body), has intrigued scientists around the world for decades. When a single magnetic atom is located inside a metal, the free electrons of the metal 'scree...
(calculus) The operation of finding the of a function. (biology) In evolution, the process by which the manifold is compacted into the relatively simple and permanent; supposed to alternate with differentiation as an agent in species' development. ...
aThe charge-doping could introduce a polaron level between the HOMO and LUMO levels, which results in a narrow er frontier orbital energy gap, lower exitation energy, and smaller bond length alternation parameter comparing to the undoped system. 充电掺杂能介绍一个polaron水平在拉人之间和 LUMO水平,...
Ueda says a consensus is now emerging among theorists that the Kondo effect can dominate and overcome the RKKY effect, provided certain conditions of electron density and electron energy states are met in the band of orbits that contributes most to the magnetic effects of the rare-earth ions, ...
