Kavli Affiliate: Gerald W. Feigenson | Summary:The presence and the properties of lipid bilayer nanometer-scale domains might be important for understanding the membranes of living cells. We used molecular dynamics (MD) simulations to investigate perturbations of a small patch of fluid-phase DPPC bilayer upon incorporation of fluorescent indocarbocyanine lipid probes commonly used to study membranes […]

Kavli Affiliate: Kyle Shen | First 5 Authors: K. M. Shen, K. M. Shen, , , | Summary: To elucidate the nature of the single-particle excitations in the undoped parent cuprates, we have performed a detailed study of Ca2CuO2Cl2 using photoemission spectroscopy. The photoemission lineshapes of the lower Hubbard band are found to be well-described […]

Kavli Affiliate: David Erickson | Summary:We present high-precision Monte Carlo data for the phase diagram of a two-species driven diffusive system, reminiscent of traffic across a narrow bridge. Earlier studies reported two phases with broken symmetry; the existence of one of these has been the subject of some debate. We show that the disputed phase […]

Kavli Affiliate: Richard D. Robinson | Summary:The Galaxy Evolution Explorer (GALEX) satellite has obtained high time resolution ultraviolet photometry during a large flare on the M4 dwarf star GJ 3685A. Simultaneous NUV (1750 – 2800A) and FUV (1350 – 1750A) time-tagged photometry with time resolution better than 0.1 s shows that the overall brightness in […]

Kavli Affiliate: Kyle Shen | First 5 Authors: K. M. Shen, K. M. Shen, , , | Summary: The evolution of Ca$_2-x$Na$_x$CuO$_2$Cl$_2$ from Mott insulator to superconductor was studied using angle-resolved photoemission spectroscopy. By measuring both the excitations near the Fermi energy as well as non-bonding states, we tracked the doping dependence of the electronic […]

Kavli Affiliate: Kyle Shen | First 5 Authors: Jian-Qi Shen, Jian-Qi Shen, , , | Summary: By using both the Lewis-Riesenfeld invariant theory and the invariant-related unitary transformation formulation, the present paper obtains the exact solutions to the time-dependent supersymmetric two-level multiphoton Jaynes-Cummings model and the Chiao-Wu model that describes the propagation of a photon […]

Kavli Affiliate: Richard D. Robinson | Summary:We present a survey of coronal forbidden lines detected in Far Ultraviolet Spectroscopic Explorer (FUSE) spectra of nearby stars. Two strong coronal features, Fe XVIII 974 A and Fe XIX 1118 A, are observed in 10 of the 26 stars in our sample. Various other coronal forbidden lines, observed […]

Kavli Affiliate: Kyle Shen | First 5 Authors: K. M. Shen, K. M. Shen, , , | Summary: We have addressed the possibility of surface ferromagnetism in Sr2RuO4 by investigating its surface electronic states by angle-resolved photoemission spectroscopy (ARPES). By cleaving samples under different conditions and using various photon energies, we have isolated the surface […]
