The intrinsic scaling-down ability, simple metal-insulator-metal (MIM) sandwich structure,
excellent performances, and complementary metal-oxide-semiconductor (CMOS) …

Scaling down materials to an atomic-layer level produces rich physical and chemical
properties as exemplified in various two-dimensional (2D) crystals including graphene …

Topologically stable matter can have a long lifetime, even if thermodynamically costly, when
the thermal agitation is sufficiently low,. A magnetic skyrmion lattice (SkL) represents a …

Electrons in condensed matter have internal degrees of freedom, such as charge, spin, and
orbital, leading to various forms of ordered states through phase transitions. However, in …

Due to the fast evolution of information technology, high-speed and scalable memory
devices are being investigated for data storage and data-driven computation. Resistive …

In the MnSi bulk chiral magnet, magnetic skyrmion strings of 17 nm in diameter appear in the
form of a lattice, penetrating the sample thickness, 10–1000 μm. Although such a bundle of …

We show that introducing long-range Coulomb interactions immediately lifts the massive
ground state degeneracy induced by geometric frustration for electrons on quarter-filled …

Charge ordering (CO) is a phenomenon in which electrons in solids crystallize into a
periodic pattern of charge-rich and charge-poor sites owing to strong electron correlations …

Dimensional and functional scaling 1 1 Functional Scaling: Suppose that a system has been
realized to execute a specific function in a given, currently available, technology. We say that …

Exploration for superconductivity is one of the research frontiers in condensed matter
physics. In strongly correlated electron systems, the emergence of superconductivity is often …
