Sub-cycle doublon-holon dynamics in one-dimensional Mott insulators revealed by two-color high-harmonic spectroscopy
Lance Hatch, Aditya Verma, Eric Schultz +7
Solid-state high-harmonic spectroscopy is becoming an emerging tool for probing nonequilibrium many-body dynamics. Yet, direct measurements of strongly driven, sub-optical-cycle dy…
The experimental observation of quantum Hall effect of l = 3 chiral charge carriers in trilayer graphene
Liyuan Zhang, Yan Zhang, J. Camacho +2
Low-energy electronic states in monolayer and bilayer graphenes present chiral charge carriers with unique and unusual properties of interest for electronic applications. Here, we…
Metal to insulator transition on the N = 0 Landau level in graphene
L. Zhang, Y. Zhang, M. Khodas +2
The magnetotransport in single layer graphene has been experimentally investigated in magnetic fields up to 18 T as a function of temperature. A pronounced T-dependence is observed…
Spin-polarized transport through domain wall in magnetized graphene
M. Khodas, I. A. Zaliznyak, D. E. Kharzeev
Atomically thin two-dimensional layer of honeycomb crystalline carbon known as graphene is a promising system for electronics. It has a point-like Fermi surface, which is very sens…
Breakdown of the N=0 Quantum Hall State in graphene: two insulating regimes
L. Zhang, J. Camacho, H. Cao +6
We studied the unusual Quantum Hall Effect (QHE) near the charge neutrality point (CNP) in high-mobility graphene sample for magnetic fields up to 18 T. We observe breakdown of the…
Short-range Charge and Spin Superstructures in Doped Layered Co Perovskites

We have investigated cobaltite relatives of the layered perovskite cuprates and nickelates, PrCaCoO () and LaSrCoO ($x = 0.61…
Polarized beam operation of the Hybrid Spectrometer at the pulsed Spallation Neutron Source
I. Zaliznyak, V. Ghosh, S. M. Shapiro +1
The concept of a neutron Hybrid Spectrometer (HYSPEC) combines the time-of-flight spectroscopy with the focusing Bragg optics and incorporates a polarized beam option. Here we desc…
Universal features of charge and spin order in a half-doped layered perovskite
I. A. Zaliznyak, J. M. Tranquada, G. Gu +2
We have investigated the peculiar structure of charge and spin ordering in the half-doped layered perovskite oxide LaSrCoO by elastic neutron scattering. Two sa…
