Ignorance Implicatures and Non-doxastic Attitude Verbs
This paper is about conjunctions and disjunctions in the scope of non-doxastic atti-
tude verbs. These constructions generate a certain type of ignorance implicature. I argue
that the best way to account for these implicatures is by appealing to a notion of contex-
tual redundancy (Schlenker, 2008; Fox, 2008; Mayr and Romoli, 2016). This pragmatic
approach to ignorance implicatures is contrasted with a semantic account of disjunctions
under `wonder' that appeals to exhaustication (Roelofsen and Uegaki, 2016). I argue
that exhaustication-based theories cannot handle embedded conjunctions, so a pragmatic
account of ignorance implicatures is superior

Resonant Two-Magnon Raman Scattering and Photoexcited States in Two-Dimensional Mott Insulators
We investigate the resonant two-magnon Raman scattering in two-dimensional
(2D) Mott insulators by using a half-filled 2D Hubbard model in the strong
coupling limit. By performing numerical diagonalization calculations for small
clusters, we find that the Raman intensity is enhanced when the incoming photon
energy is not near the optical absorption edge but well above it, being
consistent with experimental data. The absence of resonance near the gap edge
is associated with the presence of background spins, while photoexcited states
for resonance are found to be characterized by the charge degree of freedom.
The resonance mechanism is different from those proposed previously.Comment: REVTeX4, 4 pages, 3 figures, to be published in Phys. Rev. Let
Sliding Density-Wave in Sr_{14}Cu_{24}O_{41} Ladder Compounds
We used transport and Raman scattering measurements to identify the
insulating state of self-doped spin 1/2 two-leg ladders of Sr_{14}Cu_{24}O_{41}
as a weakly pinned, sliding density wave with non-linear conductivity and a
giant dielectric response that persists to remarkably high temperatures
