Charge-Stripe Crystal Phase in an Insulating Cuprate
He Zhao, Zheng Ren, Bryan Rachmilowitz +5
High-Tc superconductivity in cuprates is generally believed to arise from carrier doping an antiferromagnetic Mott (AFM) insulator. Theoretical proposals and emerging experimental…
Ultrafast time-resolved x-ray scattering reveals diffusive charge order dynamics in LaBaCuO
Matteo Mitrano, Sangjun Lee, Ali A. Husain +15
Charge order is universal among high-T cuprates but its relevance to superconductivity is not established. It is widely believed that, while static order competes with supercon…
Emergence of topologically protected states in MoTe Weyl semimetal with layer stacking order
John A. Schneeloch, Chunruo Duan, Xiaoping Wang +3
Electronic tunability in crystals with weakly-bound layers can be achieved through layer stacking order. One such example is MoTe, where the low-temperature orthorhombic T…
Nanocalorimetric Evidence for Nematic Superconductivity in the Doped Topological Insulator SrBiSe
Kristin Willa, Roland Willa, Kok Wee Song +6
Spontaneous rotational-symmetry breaking in the superconducting state of doped has attracted significant attention as an indicator for topological supe…
Three-dimensional quantum Hall effect and metal-insulator transition in ZrTe5
Fangdong Tang, Yafei Ren, Peipei Wang +8
Symmetry, dimensionality, and interaction are crucial ingredients for phase transitions and quantum states of matter. As a prominent example, the integer quantum Hall effect (QHE)…
Tracking the nematicity in cuprate superconductors: a resistivity study under uniaxial pressure
Tao Xie, Zhaoyu Liu, Yanhong Gu +14
Overshadowing the superconducting dome in hole-doped cuprates, the pseudogap state is still one of the mysteries that no consensus can be achieved. It has been suggested that the r…
Superconducting proximity effect in a topological insulator using Fe(Te,Se)
He Zhao, Bryan Rachmilowitz, Zheng Ren +6
Interest in the superconducting proximity effect has recently been reignited by theoretical predictions that it could be used to achieve topological superconductivity. Low-T…
Unambiguous connection between the Fermi surface topology and the pseudogap in BiSrCaCuO
B. Loret, Y. Gallais, M. Cazayous +7
We study the behavior of the pseudogap in overdoped BiSrCaCuO by electronic Raman scattering (ERS) and angle-resolved photoemission spectroscopy (ARPES) on th…
Coexistence of superconductivity and short-range double-stripe spin correlations in Te-vapor annealed FeTeSe with
Zhijun Xu, J. A. Schneeloch, Ming Yi +8
In as-grown bulk crystals of FeTeSe with , excess Fe () is inevitable and correlates with a suppression of superconductivity. At the same t…
Spin-wave induced phonon resonance in multiferroic BiFeO
Zhijun Xu, J. A. Schneeloch, Jinsheng Wen +13
We report the direct observation of a "resonance" mode in the lowest-energy optic phonon very near the zone center around (111) in the multiferroic BiFeO using neutron scatteri…
Evidence for magnetic-field-induced decoupling of superconducting bilayers in LaCaCuO
Ruidan Zhong, J. A. Schneeloch, Hang Chi +3
We report a study of magnetic susceptibility and electrical resistivity as a function of temperature and magnetic field in superconducting crystals of LaCaCuO…
