Here, through diamond anvil cell experiments combined with synchrotron X-ray diffraction and Raman spectroscopy techniques, we demonstrate that post-symmetrization, the crystal structure of ice X continuously distorts with pressure. Subjecting ice to pressures in excess of 308(5) GPa, we observe a first-order phase transition to ice XXII, consistent with the long-predicted phase possessing an orthorhombic crystal structure with Pbcm symmetry. We find that ice XXII is stable to pressures of at least 340(5) GPa.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"29 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148899604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we demonstrate reversible electric-field switching of phonon angular momentum in the technologically relevant ferroelectric BaTiO3. Using circularly dichroic resonant inelastic X-ray scattering, we directly resolve phonon chirality via angular momentum transfer between circularly polarized X-rays and the lattice. We observe a momentum-dependent dichroic response that switches with ferroelectric polarization, establishing a robust and non-volatile gyroelectric effect. The measured dichroism is in quantitative agreement with first-principles calculations. These results establish phonon angular momentum as an electrically controllable degree of freedom and provide a pathway towards phonon-based information and energy technologies.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"2 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148899606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we demonstrate the electrically programmable symmetry breaking of phonon polaritons via non-Hermitian dissipation engineering. In a heterostructure composed of α-MoO3 and aligned carbon nanotubes (A-CNTs), we identify the A-CNT layer as an anisotropic dissipative medium. Driven by overdamped carrier dynamics, the nanotubes preclude polariton hybridization, exerting a proximity-induced resistive coupling instead. Thus, the A-CNT layer operates as a tunable momentum-space loss filter that selectively attenuates propagation along specific crystallographic directions. By electrostatically gating the A-CNTs to regulate their Drude loss, we achieve the continuous and reversible tuning of the polariton topology with transitions from symmetric hyperbolas to asymmetric shear wavefronts. Unlike refractive-index engineering that requires strict wavevector matching, this dissipative filtering mechanism allows for topology shaping without coherent hybridization, establishing dissipation as a programmable degree of freedom in topological nanophotonics and non-Hermitian device physics.","PeriodicalId":19058,"journal":{"name":"Nature Materials","volume":"12 1","pages":""},"PeriodicalIF":41.2,"publicationDate":"2026-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148899605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show that interlayer moiré twisting, spanning a broad range of twist angles commensurate with the crystal's translational symmetry, can be controllably introduced through simple off-axis compression in ternary bulk layered van der Waals crystals. It facilitates efficient stress relaxation under mechanical loading with a further increase in the moiré twist angles and enables a substantial increase by up to 360% in room-temperature macroscopic tensile ductility, reaching 30% tensile strain along the a-b plane. Moreover, moiré twisting occurs only between layers and, thus, negligibly affects the in-plane electronic properties.
