Non-equilibrium variational cluster perturbation theory: quench dynamics of the quantum Ising model
Mohammad Zhian Asadzadeh, Michele Fabrizio, Enrico Arrigoni
We introduce a variational implementation of cluster perturbation theory (CPT) to address the dynamics of spin systems driven out of equilibrium. We benchmark the method with the q…
Superconductivity from spoiling magnetism in the Kondo lattice model
Mohammad Zhian Asadzadeh, Michele Fabrizio, Federico Becca
We find evidence that superconductivity intrudes into the paramagnetic-to-magnetic transition of the Kondo lattice model if magnetic frustration is added. Specifically, we study by…
Variational Monte Carlo approach to the two-dimensional Kondo lattice model
Mohammad Zhian Asadzadeh, Federico Becca, Michele Fabrizio
We study the phase diagram of the Kondo-lattice model with nearest-neighbor hopping in the square lattice by means of the variational Monte Carlo technique. Specifically, we analyz…
Phase diagram of the XXZ ferrimagnetic spin-(1/2, 1) chain in the presence of transverse magnetic field
A. Langari, J. Abouie, M. Z. Asadzadeh +1
We investigate the phase diagram of an anisotropic ferrimagnet spin-(1/2, 1) in the presence of a non-commuting (transverse) magnetic field. We find a magnetization plateau for the…
