Field evolution of the magnetic structure and spin Hamiltonian in CsRuO
S. D. Nabi, E. Ressouche, D. G. Mazzone +5
We report neutron diffraction under applied magnetic fields and complementary zero-field neutron spectroscopy measurements on CsRuO. Previous work [S. D. Nabi et al., Phys.…
Flux-induced strengthening of the magnetic couplings in a flat-band diamond chain
Biplab Pal, Maxime Thumin, Georges Bouzerar
The physics in flat bands has emerged as an essential field in condensed matter physics where a plethora of phenomena can be unveiled, such as anomalous transport properties, super…
Field-induced states and thermodynamics of the frustrated Heisenberg antiferromagnet on a square lattice
Andreas Honecker, M. E. Zhitomirsky, Alexander Wietek +1
We investigate the ground-state and finite-temperature properties of the - Heisenberg antiferromagnet on the square lattice in the presence of an external magnetic field.…
Optical spectra of small silver clusters with the Bethe-Salpeter formalism: a Reassessment
Xavier Blase, Ivan Duchemin
We study the optical absorption spectra of small Ag_n (n=2,4,6,8) clusters using the Bethe-Salpeter equation (BSE) formalism with a Hamiltonian built from GW quasiparticle energies…
Wide Electrical Tunability of the Valley Splitting in a Doubly gated Silicon-on-Insulator Quantum Well
Nathan Aubergier, Vincent T. Renard, Sylvain Barraud +2
The valley splitting of 2D electrons in doubly-gated silicon-on-insulator quantum wells is studied by low temperature transport measurements under magnetic fields. At the buried th…
PRIMA: PRIMAger, a far-infrared hyperspectral and polarimetric instrument
Laure Ciesla, Charles Darren Dowell, Marc Sauvage +27
The PRobe far-Infrared Mission for Astrophysics (PRIMA) is an infrared observatory for the next decade, currently in Phase A, with a 1.8m telescope actively cooled to 4.5K. On boar…
