Decades of research have predominantly focused on external factors such as temperature, load, and unloading rate, leaving the role of inherent electronic properties fundamentally unresolved. This Letter addresses this gap by demonstrating that hole doping (i.e., hole concentration) is a critical governing factor in the pressure-induced phase transformation. We experimentally establish, for the first time, that high hole-doping redirects the phase transformation by facilitating the amorphization of Si. Our simulations powered by carrier-dependent interatomic potentials reveal that the three-coordinated Si atoms are dynamically stabilized by the localized holes during the decompression from β-tin (Si-II) phase, irreversibly driving the collapse of long-range order in Si to facilitate amorphization. Furthermore, we experimentally observe the hole-facilitated amorphization in Ge and SiC, while GaAs shows a somewhat weaker yet consistent trend. Our Letter unveils the hidden role of holes from mere charge carriers to fundamental mediators of structural stability under high pressure, establishing a new perspective on the interplay between electronic and structural properties in semiconductors.","PeriodicalId":20069,"journal":{"name":"Physical review letters","volume":"137 14","pages":"146101"},"PeriodicalIF":9.4,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149207788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We show that an analogous charge-conjugating boundary condition emerges from a purely lattice duality defect. Starting from a Majorana representation of the transverse-field Ising chain, we construct a folded lattice model in which a boundary Majorana impurity implements a one-site translation of a staggered Majorana chain. In the continuum, this translation becomes a chiral fermion-parity defect: it flips the sign of the only left-moving Majorana mode while leaving the right-moving mode unchanged. When the two Majorana modes are recombined into a complex fermion in the folded geometry, this sign flip becomes the Andreev-like boundary condition. Our lattice formulation gives a microscopic interpretation of the Emery-Kivelson boundary of the two-channel Kondo problem and of Maldacena-Ludwig monopole scattering, while identifying the boundary as the interface between a Kitaev-chain symmetry-protected topological phase and a gapless chain. The same Majorana translation defect also provides a lattice realization of an axial U(1)_{A}-symmetric charge-flip boundary.","PeriodicalId":20069,"journal":{"name":"Physical review letters","volume":"137 14","pages":"146504"},"PeriodicalIF":9.4,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149207643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Typically, intrinsic Chern insulators are stabilized at odd moiré fillings, as even fillings often result in valley-balanced, topologically trivial states at zero magnetic field. In this Letter, we report the observation of a Chern insulator with C=1 state at moiré filling ν=2 in the rhombohedral octalayer graphene/hexagonal boron nitride moiré superlattice. In the vicinity of this topological phase, we also observe a robust topologically trivial correlated insulator at the same filling, highlighting the intense competition between different ground states. Observing such a Chern insulator, in particular with C=1 at ν=2 is intriguing, as the lowest moiré band in each flavor is expected to host Chern number C=1 or -1. We further demonstrate that such a state could originate from the hybridization between the low-energy moiré flat bands and high-energy remote bands in a single flavor by self-consistent Hartree-Fock calculation. Our findings extend the known topological phase diagram of rhombohedral multilayer graphene moiré systems and establish this platform as highly promising for investigating strong electron correlations and multiband hybridized transport at fillings higher than ν=1.","PeriodicalId":20069,"journal":{"name":"Physical review letters","volume":"137 14","pages":"146505"},"PeriodicalIF":9.4,"publicationDate":"2026-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149207681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
