On reduced density matrices for disjoint subsystems
Ferenc Igloi, Ingo Peschel
We show that spin and fermion representations for solvable quantum chains lead in general to different reduced density matrices if the subsystem is not singly connected. We study t…
Critical behavior and entanglement of the random transverse-field Ising model between one and two dimensions
Istvan A. Kovacs, Ferenc Igloi
We consider disordered ladders of the transverse-field Ising model and study their critical properties and entanglement entropy for varying width, , by numerical applicat…
Disordered Potts model on the diamond hierarchical lattice: Numerically exact treatment in the large-q limit
Ferenc Igloi, Loic Turban
We consider the critical behavior of the random q-state Potts model in the large-q limit with different types of disorder leading to either the nonfrustrated random ferromagnet reg…
Nonequilibrium dynamics of fully frustrated Ising models at T=0
M. Karsai, J-Ch. Angles d'Auriac, F. Igloi
We consider two fully frustrated Ising models: the antiferromagnetic triangular model in a field of strength, , as well as the Villain model on the square lattice. After…
