Topological Gap Opening without Symmetry Breaking from Dynamical Quantum Correlations

Francesca Paoletti, Laura Fanfarillo, Massimo Capone +1

Topological phase transitions are typically associated with the formation of gapless states. Spontaneous symmetry breaking can lead to a gap opening thereby obliterating the topolo…

Dimensionality-driven metal-insulator-transition in spin-orbit coupled SrIrO

P. Schütz, D. Di Sante, L. Dudy +10

Upon reduction of the film thickness we observe a metal-insulator transition in epitaxially stabilized, spin-orbit coupled SrIrO ultrathin films. By comparison of the experimen…

Doping driven metal-insulator transitions and charge orderings in the extended Hubbard model

K. J. Kapcia, S. Robaszkiewicz, M. Capone +1

We perform a thorough study of an extended Hubbard model featuring local and nearest-neighbor Coulomb repulsion. Using dynamical mean-field theory we investigated the zero temperat…

First order character and observable signatures of topological quantum phase transitions

A. Amaricci, J. C. Budich, M. Capone +2

Topological quantum phase transitions are characterised by changes in global topological invariants. These invariants classify many body systems beyond the conventional paradigm of…

Local moment dynamics and screening effects in doped charge-transfer insulators

A. Amaricci, N. Parragh, M. Capone +1

By means of Dynamical Mean-Field Theory we investigate the spin response function of a model for correlated materials with d- or f-electrons hybridized with more delocalized ligand…

Polaron Crossover and Bipolaronic Metal-Insulator Transition in the half- filled Holstein model

M. Capone, S. Ciuchi

The formation of a finite density multipolaronic state is analyzed in the context of the Holstein model using the Dynamical Mean-Field Theory. The spinless and spinful fermion case…

Interplay between Spin and Phonon Fluctuations in the double-exchange model for the manganites

M. Capone, S. Ciuchi

We present exact solutions, mainly analytical, for the two-site double-exchange-Holstein model, that allow us to draw a complete picture of the role of both phonon and spin quantum…

Theory of the Metal-Paramagnetic Mott-Jahn-Teller Insulator Transition in A_4C_{60}

M. Capone, M. Fabrizio, P. Giannozzi +1

We study the unconventional insulating state in A_4C_{60} with a variety of approaches, including density functional calculations and dynamical mean-field theory. While the former…
