Examples of atoms in singlet, doublet, and triplet states. In quantum mechanics, a triplet state, or spin triplet, is the quantum state of an object such as an electron, atom, or molecule, having a quantum spin S = 1. It has three allowed values of the spin's projection along a given axis m S = −1, 0, or +1, giving the name "triplet".
Early investigations [5] studied the coexistence of conventional s-wave superconductivity with itinerant ferromagnetism. However, the scenario of spin-triplet pairing soon gained the upper hand. [6] [7] A mean-field model for coexistence of spin-triplet pairing and ferromagnetism was developed in 2005. [8] [9]
Superconductivity in UTe 2 appears to be a consequence of triplet electrons spin-pairing. [2] The material acts as a topological superconductor, stably conducting electricity without resistance even in high magnetic fields. [1] It has superconducting transition temperature at Tc= 2K. [3]
Chin-Sen Ting is a Chinese American physicist from Taiwan and an academic.He is a distinguished professor of physics at the University of Houston. [1]Through his research, Ting has explored condensed matter theories in semiconductors, magnetism, superconductivity, and correlated electron systems, focusing on solid state systems using methods like diagrammatic many body theory and Monte Carlo ...
The superscript three (read as triplet) indicates that the multiplicity 2S+1 = 3, so that the total spin S = 1. This spin is due to two unpaired electrons, as a result of Hund's rule which favors the single filling of degenerate orbitals. The triplet consists of three states with spin components +1, 0 and –1 along the direction of the total ...
In physics, reentrant superconductivity is an effect observed in systems that lie close to the boundary between ferromagnetic and superconducting.By its very nature (normal) superconductivity (condensation of electrons into the BCS ground state) cannot exist together with ferromagnetism (condensation of electrons into the same spin state, all pointing in the same direction).
The radical-pair mechanism explains how external magnetic fields can prevent radical-pair recombination with Zeeman interactions, the interaction between spin and an external magnetic field, and shows how a higher occurrence of the triplet state accelerates radical reactions because triplets can proceed only to products, and singlets are in ...
The spin-dependence of Andreev reflection gives rise to the Point contact Andreev reflection technique, whereby a narrow superconducting tip (often niobium, antimony or lead) is placed into contact with a normal material at temperatures below the critical temperature of the tip. By applying a voltage to the tip, and measuring differential ...
