There is a long time gap between the formulation of the basic theory of low-dimensional (low-
D) magnetism as advanced by Ising, Heisenberg and Bethe and its experimental …

Suitable for researchers and graduate students in physics and material science," Physical
Acoustics in the Solid State" reviews the modern aspects in the field, including many …

Among the series of polyanionic positive electrodes for sodium-ion batteries having the
general formula Na3V2 (PO4) 2F3–y O y (0≤ y≤ 2), the composition Na3V2 (PO4) 2F3 (y …

In recent times, ab initio density functional theory has emerged as a powerful tool for making
the connection between models and materials. Insulating transition metal oxides with a …

We examine two recently proposed models of charge ordering (CO) in the nominally 1 4-
filled, quasi-one-dimensional (1D) organic charge-transfer solids (CTS). The two models are …

We have performed high-pressure experiments on β-vanadium bronzes, β-A0. 33V2O5 (A=
Li+, Na+, Ag+, Ca2+, Sr2+ and Pb2+) which are quasi-one-dimensional conductors. All of …

Charge fluctuation and charge-ordering phenomena in compounds based on the 3d
electrons of transition-metal ions and 4f electrons of rare-earth ions are reviewed with …

We have analyzed the experimental evidence of charge and orbital ordering in La 0.5 Sr 1.5
MnO 4 using first principles band structure calculations. Our results suggest the presence of …

Abstract The “devil's staircase”-type phase transition in the quarter-filled spin-ladder
compound NaV 2 O 5 has been discovered at low temperature and high pressure by …

Transition metal oxides that realize s= 1/2 or s= 1 quantum spin systems with low
dimensionality or geometrically restricted connectivity are often described using simple …
