The discovery of ferroelectricity in two-dimensional (2D) van der Waals (vdW) materials has
brought important functionalities to the 2D materials family, and may trigger a revolution in …

Structurally different from conventional oxide ferroelectrics with rigid lattices, van der Waals
(vdW) ferroelectrics have stable layered structures with a combination of strong intralayer …

The superconducting analogue to the semiconducting diode, the Josephson diode, has long
been sought with multiple avenues to realization being proposed by theorists,–. Showing …

Quantum geometric properties of Bloch wave functions in solids, that is, Berry curvature and
the quantum metric, are known to significantly influence the ground-and excited-state …

Quantum geometry in condensed-matter physics has two components: the real part quantum
metric and the imaginary part Berry curvature. Whereas the effects of Berry curvature have …

Since the discovery of Rochelle salt a century ago, ferroelectric materials have been
investigated extensively due to their robust responses to electric, mechanical, thermal …

Two-dimensional (2D) ferroelectrics, which are rare in nature, enable high-density
nonvolatile memory with low energy consumption. Here, we propose a theory of bilayer …

Given its innate coupling with wavefunction geometry in solids and its potential to boost the
solar energy conversion efficiency, the bulk photovoltaic effect (BPVE) has been of …

The photoexcitation life cycle from incident photon (and creation of photoexcited electron–
hole pair) to ultimate extraction of electrical current is a complex multiphysics process …

In noncentrosymmetric materials, the responses (for example, electrical and optical)
generally depend on the direction of the external stimuli, called nonreciprocal phenomena …
