Electron spins interaction in the spin-Peierls phase of the organic spin chain (o -DMTTF) 2 X (X = Cl, Br, I)

Autor: Soriano, Loic, Pilone, Olivier, Kuz'Min, Michael D., Vezin, Herve, Jeannin, Olivier, Fourmigué, Marc, Orio, Maylis, Bertaina, Sylvain

We investigate the electron spin resonance of the organic spin-Peierls chain (o-DMTTF)2X with X = Cl, Br and I. We describe the temperature dependence of the spin gap during the phase transition and quantify the dimerization parameter $\delta$. At th

Magnetic properties and underlying magnetic models of the synthetic A$_2$Cu$_3$O(SO$_4)_3$ fedotovite (A = K) and puninite (A = Na) minerals, as well as the mixed euchlorine-type NaKCu$_3$O(SO$_4)_3$ are reported. We show that all these compounds con

Experimental protection of quantum coherence by using a phase-tunable image drive

Autor: Bertaina, Sylvain, Vezin, Hervé, De Raedt, Hans, Chiorescu, Irinel

Publikováno v: NPJ Scientific Report vol 10 21642 (2020)

The protection of qubit coherence is an essential task in order to build a practical quantum computer able to manipulate, store and read quantum information with a high degree of fidelity. Recently, it has been proposed to increase the operation time
