NUMERICAL DETERMINATION OF THE ORDER OF PHASE-TRANSITIONS IN ISING SYSTEMS WITH MULTISPIN INTERACTIONS
(American Physical Soc, 1991-01-01)
The method of the fourth-order cumulant of Challa, Landau, and Binder is used together with the Monte Carlo histogram technique of Ferrenberg and Swendsen to study the order of the phase transitions of two-dimensional Ising ...

DQ-DRENAR: a new NMR technique to measure site-resolved magnetic dipole-dipole interactions in multispin-1/2 systems: theory and validation on crystalline phosphates
(American Institute of Physics - AIPCollege Park, 2013)
A new solid state NMR technique is described for measuring homonuclear dipole-dipole interactions in multi-spin-1/2 systems under magic-angle spinning conditions. Re-coupling is accomplished in the form of an effective ...
Fase nemática no modelo J1-J2
(2020)
Neste projeto, estudamos através de simulações de Monte Carlo o modelo J1-J2 numa rede quadrada bidimensional com variáveis de Ising na presença de campo magnético externo. Neste modelo, a interação entre primeiros vizinhos ...
Control of spin dynamics with laser pulses: Generation of entangled states of donor-bound electrons in a Cd 1-xMn xTe quantum well
(American Physical Society, 2005-12)
A quantum-mechanical many-particle system may exhibit nonlocal behavior in that measurements performed on one of the particles can affect a second one that is far apart. These so-called entangled states are crucial for the ...
