The rapid development of information technology has led to urgent requirements for high
efficiency and ultralow power consumption. In the past few decades, neuromorphic …

Complex oxides with 4 d and 5 d transition-metal ions recently emerged as a new paradigm
in correlated electron physics, due to the interplay between spin–orbit coupling and electron …

Orbital occupancy control in correlated oxides allows the realization of new electronic
phases and collective state switching under external stimuli. The resultant structural and …

Strong electronic correlations are often associated with the proximity of a Mott-insulating
state. In recent years however, it has become increasingly clear that the Hund's rule …

A review of the basic ideas and techniques of the spectral density-functional theory is
presented. This method is currently used for electronic structure calculations of strongly …

We investigated the electronic structure of 5 d transition-metal oxide Sr 2 IrO 4 using angle-
resolved photoemission, optical conductivity, x-ray absorption measurements, and first …

A wide variety of experimental results and theoretical investigations in recent years have
convincingly demonstrated that several transition metal oxides and other materials have …

This review presents a summary and evaluations of the superconducting properties of the
layered ruthenate Sr 2 RuO 4 as they are known in the autumn of 2011. This paper appends …

Superconductivity in so-called unconventional superconductors is nearly always found in
the vicinity of another ordered state, such as antiferromagnetism, charge density wave …

Pairing symmetry is a fundamental property that characterizes a superconductor. For the iron-
based high-temperature superconductors,, an s±-wave pairing symmetry has received …
