Fermi-Liquid Resistivity: Dynamical Mean-Field Theory Meets Experiment
Fabian B. Kugler, Jeremy Lee-Hand, Harrison LaBollita +6
Direct-current resistivity is a key probe for the physical properties of materials. In metals, Fermi-liquid (FL) theory serves as the basis for understanding transport. A beh…
Capping effects on spin and charge excitations in parent and superconducting Nd1-xSrxNiO2
S. Fan, H. LaBollita, Q. Gao +19
Superconductivity in infinite layer nickelates Nd1-xSrxNiO2 has so far been achieved only in thin films raising questions on the role of substrates and interfaces. Given the challe…
Assessing the formation of spin and charge stripes in LaNiO from first-principles
Harrison LaBollita, Victor Pardo, Michael R. Norman +1
We employ correlated density-functional theory methods (DFT + Hubbard ) to investigate the spin-density wave state of the bilayer Ruddlesden-Popper (RP) nickelate LaNi$_{2…
Electronic correlations, layer distinction, and electron doping in the alternating single-layer trilayer LaNiO polymorph
Harrison LaBollita, Soumen Bag, Jesse Kapeghian +1
We employ a density-functional theory plus dynamical mean-field theory framework to investigate the correlated electronic structure of the alternating single-layer trilayer (1313)…
Electronic structure and magnetic tendencies of trilayer LaNiO under pressure: structural transition, molecular orbitals, and layer differentiation
Harrison LaBollita, Jesse Kapeghian, Michael R. Norman +1
Motivated by the recent observation of superconductivity in the pressurized trilayer LaNiO Ruddlesden-Popper (RP) nickelate, we explore its structural, electronic, a…
Hydrogen is not necessary for superconductivity in topotactically reduced nickelates
Purnima P. Balakrishnan, Dan Ferenc Segedin, Lin Er Chow +19
A key open question in the study of layered superconducting nickelate films is the role that hydrogen incorporation into the lattice plays in the appearance of the superconducting…
Pressure effects on the electronic structure and magnetic properties of infinite-layer nickelates
Shekhar Sharma, Myung-Chul Jung, Harrison LaBollita +1
Motivated by the discovery of superconductivity in infinite-layer nickelates RNiO (R= rare-earth), and the subsequent enhancement of their T with pressure, we investigate t…
