Photoemission Spectroscopy of Low-Dimensional Charge-Density-Wave and Superconducting Materials

The discovery in 1986 of the high-Tc superconducting cuprates has ushered in a new era of research in condensed matter physics. There is still a great interest for these materials, which stems not only from the lack of a clear theoretical picture, but also ...

Improved confinement in high-density H-modes via modification of the plasma boundary with lower hybrid waves

Christian Gabriel Theiler, Yu Lin, Peng Xu

Injecting Lower Hybrid Range of Frequency (LHRF) waves into Alcator C-Mod's high-density H-mode plasmas has led to enhanced global energy confinement by increasing pedestal temperature and pressure gradients, decreasing the separatrix density, modifying th ...

Superconducting phase in the layered dichalcogenide 1T-TaS_{2} upon inhibition of the metal-insulator transition

Henrik Moodysson Rønnow, László Forró, Helmuth Berger, Marco Grioni, Julian Piatek, Ping-Hui Lin, Balazs Sipos, Peng Xu

When a Mott metal-insulator transition is inhibited by a small amount of disorder in the layered dichalcogenide 1T-TaS2, an inhomogeneous superconducting state arises below T=2.1 K and coexists with a nearly commensurate charge-density wave. By angle-resol ...

Measurement of Magnetic Excitations in the Two-Dimensional Antiferromagnetic Sr2CuO2Cl2 Insulator Using Resonant X-Ray Scattering: Evidence for Extended Interactions

Helmuth Berger, Henrik Moodysson Rønnow, Marco Grioni, Thorsten Schmitt, Bastien Dalla Piazza, Ping-Hui Lin, Marco Guarise, Peng Xu

We measured the momentum dependence of magnetic excitations in the model spin-1/2 2D antiferromagnetic insulator Sr2CuO2Cl2 (SCOC). We identify a single-spin-wave feature and a multimagnon continuum, with different polarization dependences. The spin waves ...
