Holographic quantum criticality and strange metal transport
Bom Soo Kim, Elias Kiritsis, Christos Panagopoulos
A holographic model of a quantum critical theory at a finite but low temperature, and finite density is studied. The model exhibits non-relativistic z=2 Schrödinger symmetry and is…
Tunable magnetic interaction at the atomic scale in oxide heterostructures
J. W. Seo, W. Prellier, P. Padhan +9
We report on a systematic study of a number of structurally identical but chemically distinct transition metal oxides in order to determine how the material-specific properties suc…
Skyrmions in a Doped Antiferromagnet
I. Raicevic, Dragana Popovic, C. Panagopoulos +4
Magnetization and magnetoresistance have been measured in insulating antiferromagnetic La_{2}Cu_{0.97}Li_{0.03}O_{4} over a wide range of temperatures, magnetic fields, and field o…
Relaxor characteristics at the interfaces of [NdMnO3/SrMnO3/LaMnO3] superlattices
J. W. Seo, B. T. Phan, J. Stahn +2
We have investigated the magnetic properties of transition metal oxide superlattices with broken inversion symmetry composed of three different antiferromagnetic insulators, [NdMnO…
Transparent and flexible polymerized graphite oxide thin film with frequency-dependent dielectric constant
D. W. Lee, J. W. Seo, G. R. Jelbert +4
Here we report on the preparation of transparent and flexible polymerized graphite oxide, which is composed of carbons with sp3-hybridized orbitals and a non-planar ring structure,…
Nernst effect and diamagnetic response in a stripe model of superconducting cuprates
Ivar Martin, C. Panagopoulos
We examine the possibility that the experimentally observed enhancement of superconducting (SC) fluctuations above the SC transition temperature in the underdoped cuprates is cause…
