Effect of dipolar interaction in molecular crystals.
In this paper we investigate the ground state and the nature of the transition from an orientational ordered phase at low temperature to the disordered state at high temperature in a molecular crystal. Our model is a Potts model which takes into account the exchange interaction J between nearest-neighbor molecules and a dipolar interaction between molecular axes in three dimensions. The dipolar...
متن کاملLong-range quantum gates using dipolar crystals.
We propose the use of dipolar spin chains to enable long-range quantum logic between distant qubits. In our approach, an effective interaction between remote qubits is achieved by adiabatically following the ground state of the dipolar chain across the paramagnet to crystal phase transition. We demonstrate that the proposed quantum gate is particularly robust against disorder and derive scaling...

متن کاملCritical Dynamics of Dipolar Ferromagnets
The dynamics of isotropic ferromagnets as EuO, EuS and Fe has been in focusever since the very beginnings ofthe field of critical dynamics. Despite the largeamount of experimental [1—6]and theoretical investigations [7,8], there remain importantopen problemswhich havenot been resolved up to now. (i) The expected crossover from isotropic to dipolar critical behaviour, accompanied by a change of ...
متن کاملCRITICAL DYNAMICS AND DIPOLAR INTERACTION IN EuO
Recent neutron scattering studies of the critical behaviour of isotropic ferromagnets revealed the apparent contradiction between a good agreement with dynamic scaling at T = T, and drastic deviations from scaling at T > Tc. In EuO the experimental findings are consistent with latest theoretical results taking into account dipolar interactions. The ferromagnetic-paramagnetic phase transition at...
