WitrynaNoteworthy, the spin S couples to the QI via the Ising-type exchange interaction.} As the Majorana zero-modes (MZMs) at the edges of the TSC chain are overlapped, we counterintuitively find a regime wherein the Ising term modulates the localization of a fractionalized and resonant MZM at the QI site. Interestingly enough, the fermionic … WitrynaDes spins d'Ising en interaction ferromagnetique sont places sur un reseau fractal (tel qu'un cluster de percolation) avec T c =0, et sont dotes d'une dynamique simple de retournement de spin.

Witryna2. The Ising model has a huge number of different interpretations, usually with no link to magnetism at all, and the interpretation of the coupling constant J i j is different in each case. Note also that, even if you restrict yourself to the magnetic interpretation, the Ising model was introduced before the proper microscopic origins of ... WitrynaThe theoretical description of phase transitions is very difficult. We have already explained some reasons for this in the preceding sections. Only a few models can be treated in the framework of statistical mechanics without large numerical efforts. One is due to Lenz (1920), and was later on worked out in detail by his pupil Ising (1925). indexar ficheros

WitrynaThe Ising measure at β =∞ concentrates on the two ground states: all the spins are aligned. As β varies continuously from 0 to inﬁnity, the interaction between the spins increase, which favors the alignment between them.
