Fractional quantum ferroelectricity

open access: yesNature Communications, 2023
For an ordinary ferroelectric, the magnitude of the spontaneous electric polarization is at least one order of magnitude smaller than that resulting from the ionic displacement of the lattice vectors, and the direction of the spontaneous electric ...

Stabilization of sliding ferroelectricity through exciton condensation [PDF]

open access: yesNature Communications
Sliding ferroelectricity is a phenomenon that arises from the insurgence of spontaneous electronic polarization perpendicular to the layers of two-dimensional systems upon the relative sliding of the atomic layer constituents. Because of the weak van der

Enhanced superconductivity and coexisting ferroelectricity at oxide interfaces [PDF]

open access: yesNature Communications
The coexistence of superconductivity and ferroelectricity is rare due to their conflicting requirements: superconductivity relies on free charge carriers, whereas ferroelectricity typically occurs in insulating systems.

Ferroelectricity-Driven Phonon Berry Curvature and Nonlinear Phonon Hall Transports [PDF]

open access: yes
Berry curvature (BC) governs topological phases of matter and generates anomalous transport. When a magnetic field is applied, phonons can acquire BC indirectly through spin–lattice coupling, leading to a linear phonon Hall effect.

Ferroelectricity in biological building blocks: Slipping on a banana peel?

open access: yesJournal of Advanced Dielectrics, 2023
Ferroelectricity in biological system has been anticipated both theoretically and experimentally over the past few decades. Claims of ferroelectricity in biological systems have given rise to confusion and methodological controversy.

Biferroelectricity of a homochiral organic molecule in both solid crystal and liquid crystal phases

open access: yesNature Communications, 2022
Ferroelectricity normally exists in either solid crystals or liquid crystals. Here, the authors report a homochiral organic compound which shows ferroelectricity in both solid crystal and liquid crystal phases.

A ferroelectric memristor [PDF]

open access: yesNature Materials, 2012
Memristors are continuously tunable resistors that emulate synapses. Conceptualized in the 1970s, they traditionally operate by voltage-induced displacements of matter, but the mechanism remains controversial. Purely electronic memristors have recently emerged based on well-established physical phenomena with albeit modest resistance changes.

Pressure-induced ferroelectric-like transition creates a polar metal in defect antiperovskites Hg3Te2X2 (X = Cl, Br)

open access: yesNature Communications, 2021
Generally, ferroelectricity in ABO3 perovskites is suppressed by hydrostatic compression, but the evidence for pressure-induced ferroelectricity remains elusive. Here, the authors find a direct ferroelectric-like structural transition induced by pressure
