Flat Electron Bands with Bad Valley Quantum Numbers in Twisted Bi-Layer Graphene
J. P. Rodriguez
We compute the energy spectrum of a nearest-neighbor electron hopping model for bi-layer graphene at commensurate twist angles. Specifically, we focus on the simplest bi-layer latt…
Quantum-Critical Spin-Density Waves in Iron-Selenide High-Tc Superconductors
J. P. Rodriguez
Hidden spin-density waves (hSDW) with Neel ordering vector (pi,pi) have been proposed recently as parent groundstates to electron-doped iron-selenide superconductors. Doping such g…
Spin Resonances in Iron-Selenide High-Tc Superconductors by Proximity to Hidden Spin Density Wave
J. P. Rodriguez
Recent inelastic neutron scattering studies by Pan et al., Nature Communications 8, 123 (2017), find evidence for spin excitations at energies above the quasi-particle gap in an ir…
Superconductivity by Hidden Spin Fluctuations in Electron-Doped Iron Selenide
J. P. Rodriguez
Berg, Metlitski and Sachdev, Science 338, 1606 (2012), have shown that the exchange of hidden spin fluctuations by conduction electrons with two orbitals can result in high-tempera…
Critical phenomena in an extended Dicke model
J. P. J. Rodriguez, S. A. Chilingaryan, B. M. Rodríguez-Lara
Spectral characterization is a fundamental step in the development of useful quantum technology platforms. Here, we study an ensemble of interacting qubits coupled to a single quan…
Isotropic Cooper Pairs with Emergent Sign Changes in Single-Layer Iron Superconductor
J. P. Rodriguez
We model a single layer of heavily electron-doped FeSe by spin-1/2 moments over a square lattice of iron atoms that include the 3d xz and 3d yz orbitals, at strong on-site Coulomb…
