Detuning the Honeycomb of -RuCl: Pressure-Dependent Optical Studies Reveal Broken Symmetry
Tobias Biesner, Sananda Biswas, Weiwu Li +10
The honeycomb Mott insulator -RuCl loses its low-temperature magnetic order by pressure. We report clear evidence for a dimerized structure at GPa and observe the brea…
Superconductivity in correlated BEDT-TTF molecular conductors: critical temperatures and gap symmetries
Karim Zantout, Michaela Altmeyer, Steffen Backes +1
Starting from an {\it ab initio}-derived two-site dimer Hubbard hamiltonian on a triangular lattice, we calculate the superconducting gap functions and critical temperatures for re…
Cu-Sb dumbbell arrangement in the spin-orbital liquid candidate BaCuSbO
Michaela Altmeyer, Frederic Mila, Andrew Smerald +1
The absence of both spin freezing and of a static Jahn-Teller effect have lead to the proposition that BaCuSbO is a quantum spin-orbital liquid. However, theoretical un…
Role of vertex corrections in the matrix formulation of the random phase approximation for the multiorbital Hubbard model
Michaela Altmeyer, Daniel Guterding, P. J. Hirschfeld +3
In the framework of a multiorbital Hubbard model description of superconductivity, a matrix formulation of the superconducting pairing interaction that has been widely used is desi…
Near-degeneracy of extended and order parameters in quasi-two-dimensional organic superconductors
Daniel Guterding, Michaela Altmeyer, Harald O. Jeschke +1
The symmetry of the superconducting order parameter in quasi-two-dimensional BEDT-TTF organic superconductors is a subject of ongoing debate. We report ab initio density functional…
Magnetism, spin texture and in-gap states: Atomic specialization at the surface of oxygen-deficient SrTiO
Michaela Altmeyer, Harald O. Jeschke, Oliver Hijano-Cubelos +7
Motivated by recent spin- and angular-resolved photoemission (SARPES) measurements performed on the two-dimensional electronic states confined near the (001) surface of SrTiO i…
Evidence for eight node mixed-symmetry superconductivity in a correlated organic metal
Daniel Guterding, Sandra Diehl, Michaela Altmeyer +10
We report a combined theoretical and experimental investigation of the superconducting state in the quasi-two-dimensional organic superconductor -(ET)Cu[N(CN)]Br. Applyi…
Role of layer packing for the electronic properties of the organic superconductor (BEDT-TTF)Ag(CF)(TCE)
Michaela Altmeyer, Roser Valenti, Harald O. Jeschke
The charge transfer compound (BEDT-TTF)Ag(CF)(TCE) crystallizes in three polymorphs with different alternating layers: While a phase with a packing motif has a low…
Effect of isoelectronic doping on honeycomb lattice iridate A_2IrO_3
S. Manni, Sungkyun Choi, I. I. Mazin +5
We have investigated experimentally and theoretically the series (NaLi)IrO. Contrary to what has been believed so far, only for the system for…
