Open AccessBand-selective Holstein polaron in Luttinger liquid material A0.3MoO3 (A = K, Rb)
(Quasi-)one-dimensional systems exhibit various fascinating properties such as Luttinger liquid behavior, Peierls transition, novel topological phases, and the accommodation of unique quasiparticles (e.g., spi...

Giant thermal Hall conductivity in the pseudogap phase of cuprate superconductors
The nature of the pseudogap phase of the copper oxides (‘cuprates’) remains a puzzle. Although there are indications that this phase breaks various symmetries, there is no consensus on its fundamental nature1. Fe...

Thermodynamic signatures of quantum criticality in cuprate superconductors
The three central phenomena of cuprate (copper oxide) superconductors are linked by a common do** level p*—at which the enigmatic pseudogap phase ends and the resistivity exhibits an anomalous linear dependence...

Open AccessPseudogap phase of cuprate superconductors confined by Fermi surface topology
The properties of cuprate high-temperature superconductors are largely shaped by competing phases whose nature is often a mystery. Chiefly among them is the pseudogap phase, which sets in at a do** p* that is m...

Open AccessJahn-Teller distortion driven magnetic polarons in magnetite
The first known magnetic mineral, magnetite, has unusual properties, which have fascinated mankind for centuries; it undergoes the Verwey transition around 120 K with an abrupt change in structure and electric...

Competition between heavy fermion and Kondo interaction in isoelectronic A-site-ordered perovskites
With current research efforts shifting towards the 4d and 5d transition metal oxides, understanding the evolution of the electronic and magnetic structure as one moves away from 3d materials is of critical import...

Open AccessZhang-Rice physics and anomalous copper states in A-site ordered perovskites
In low dimensional cuprates several interesting phenomena, including high Tc superconductivity, are deeply connected to electron correlations on Cu and the presence of the Zhang-Rice (ZR) singlet state. Here, we ...

Open AccessHigh pressure route to generate magnetic monopole dimers in spin ice
The gas of magnetic monopoles in spin ice is governed by one key parameter: the monopole chemical potential. A significant variation of this parameter could access hitherto undiscovered magnetic phenomena aris...

Enhancement of the Nernst effect by stripe order in a high-Tc superconductor
The Nernst effect in metals is highly sensitive to two kinds of phase transition: superconductivity and density-wave order. The large positive Nernst signal observed in hole-doped high-Tc superconductors above th...

Identification of a new type of electronic state in the magnetoresistive orthomanganites
PEROVSKITES of composition Ln1–xAxMnO3 (where Ln and A are rare-earth and alkaline-earth elements respectively) have become the focus of scientific and technological interest because of their extraordinary elect...
