Selective Mottness as a key to iron superconductors
Luca de' Medici, Gianluca Giovannetti, Massimo Capone
The phase diagram of the high-Tc cuprates is dominated by the Mott insulating phase of the parent compounds. As we approach it from large doping, a standard Fermi-liquid gradually…
Dynamical quantum phase transitions and broken-symmetry edges in the many-body eigenvalue spectrum
Giacomo Mazza, Michele Fabrizio
Many body models undergoing a quantum phase transition to a broken-symmetry phase that survives up to a critical temperature must possess, in the ordered phase, symmetric as well a…
XXZ spin-1/2 representation of a finite-U Bose-Hubbard chain at half-integer filling
Domenico Giuliano, Davide Rossini, Pasquale Sodano +1
Using a similarity Hamiltonian renormalization procedure, we determine an effective spin-1/2 representation of the Bose-Hubbard model at half-integer filling and at a finite on-sit…
Spin-liquid versus spiral-order phases in the anisotropic triangular lattice
Luca F. Tocchio, Hélène Feldner, Federico Becca +2
We study the competition between magnetic and spin-liquid phases in the Hubbard model on the anisotropic triangular lattice, which is described by two hopping parameters t and t' i…
Gapless spin-liquid phase in the kagome spin-1/2 Heisenberg antiferromagnet
Yasir Iqbal, Federico Becca, Sandro Sorella +1
We study the energy and the static spin structure factor of the ground state of the spin-1/2 quantum Heisenberg antiferromagnetic model on the kagome lattice. By the iterative appl…
Augmented hybrid exact-diagonalization solver for dynamical mean field theory
C. Weber, A. Amaricci, M. Capone +1
We present a new methodology to solve the Anderson impurity model, in the context of dynamical mean-field theory, based on the exact diagonalization method. We propose a strategy t…
