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

As a strongly correlated electron material, vanadium dioxide (VO 2) has been a focus of
research since its discovery in 1959, owing to its well-known metal–insulator transition …

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 …

Electrons in correlated insulators are prevented from conducting by Coulomb repulsion
between them. When an insulator-to-metal transition is induced in a correlated insulator by …

Although phase transitions have long been a centerpiece of condensed matter materials
science studies, a number of recent efforts focus on potentially exploiting the resulting …

Studies of the electromagnetic response of various classes of correlated electron materials
including transition-metal oxides, organic and molecular conductors, intermetallic …

Memory effects are ubiquitous in nature and are particularly relevant at the nanoscale where
the dynamical properties of electrons and ions strongly depend on the history of the system …

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

Complex systems in condensed phases involve a multidimensional energy landscape, and
knowledge of transitional structures and separation of time scales for atomic movements is …

Unlike conventional optics, plasmonics enables unrivaled concentration of optical energy
well beyond the diffraction limit of light. However, a significant part of this energy is …
