Roughness-induced magnetic decoupling at organic-inorganic interface

Hiroki Ono, Yoshitaka Umeda, Kaito Yoshida +8

We have investigated structural, electronic and magnetic properties of HPc on FeN/Fe using low-energy electron diffraction and soft x-ray absorption spectroscopy/x-ray magn…

Nanostructural polymorphism in the low-birefringence chiral phase of an achiral bent-shaped dimer

Khoa V. Le, Michael R. Tuchband, Hiroshi Iwayama +3

Polymorphism, the phenomenon that a species can exist in many discrete forms, is common in nature, such as hair colors in an animal species, flower colors in a tree species, and bl…

Specific chemical bond relaxation unravelled by analysis of shake-up satellites in the oxygen single site double core hole spectrum of CO

Anthony Ferté, Francis Penent, Jérôme Palaudoux +7

We developed recently [A. Ferté, et al., J. Phys. Chem. Lett. 11, 4359 (2020)] a method to compute single site double core hole (ssDCH or K) spectra. We refer to that method…

Superfluorescence, free-induction decay, and four-wave mixing: propagation of free-electron laser pulses through a dense sample of helium ions

James R Harries, Hiroshi Iwayama, Susumu Kuma +9

We report an experimental and numerical study of the propagation of free-electron laser pulses (wavelength 24.3 nm) through helium gas. Ionisation and excitation populates the He$^…

Simultaneous measurements of super-radiance at multiple wavelengths from helium excited states: (I) Experiment

Kyo Nakajima, James R. Harries, Hiroshi Iwayama +8

In this paper, we report the results of measurements of the intensities and delays of super-radiance decays from excited helium atoms at multiple wavelengths. The experiment was pe…
