Die neuen Phosphidosilicate Li2SiP2 und LiSi2P3 wurden aus den Elementen bei 1123 K synthetisiert und durch Einkristallstrukturanalyse charakterisiert. Li2SiP2 (I41/acd, Z=32, a=12.111(1) Å, c=18.658(2) Å) enthält zwei sich durchdringende Diamant‐analoge Tetraedernetzwerke aus eckenverknüpften T2‐Supertetraedern [(SiP4/2)4]. In der komplexen Struktur von LiSi2P3 (I41/a, Z=100, a=18.4757(3) Å, c=35.0982(6) Å) liegen Sphalerit‐analoge sich durchdringende Netzwerke aus T4‐ und T5‐Supertetraedern mit je einer gemeinsamen SiP4‐Gruppe vor. Lithium ist in den Zwischenräumen der Supertetraeder durch vier bis sechs Phosphoratome koordiniert. Temperaturabhängige 7Li‐MAS‐NMR‐Spektren deuten auf eine hohe Beweglichkeit der Li+‐Ionen mit geringen Aktivierungsenergien von 0.1 eV für Li2SiP2 und 0.07 eV für LiSi2P3.

“…CdSiP 2 and the germanate ZnGeP 2 with the tetragonal chalcopyrite-type structure have been studied as nonlinear optical materials. [11,12] Recently reported Li-phosphidosilicates like LiSi 2 P 3 [13] and Li 2 SiP 2 [2] attract considerable interest as Li ion conductors. Due to the same fundamental tetrahedral building unit, the structural chemistry of phosphidosilicates resembles to some extend those of the much bigger families of oxido-and nitridosilicates.…”

“…Indeed, this feature allows CBPs to be used for all-optical diagnostics of anomalous Hall and topological phases, as well as pumped or periodically driven systems, e.g., as in Ref. [38,39]. Optical probes of the latter are particularly appealing since transport measurements require contacts that often complicate and destroy the novel electron distributions and coherences of driven systems.…”

Plasmons, the collective oscillations of interacting electrons, possess emergent properties that dramatically alter the optical response of metals. We predict the existence of a new class of plasmonschiral Berry plasmons (CBPs)-for a wide range of 2D metallic systems including gapped Dirac materials. As we show, in these materials the interplay between Berry curvature and electronelectron interactions yields chiral plasmonic modes at zero magnetic field. The CBP modes are confined to system boundaries, even in the absence of topological edge states, with chirality manifested in split energy dispersions for oppositely directed plasmon waves. We unveil a rich CBP phenomenology and propose setups for realizing them, including in anomalous Hall metals and optically pumped 2D Dirac materials. Realization of CBPs will offer a powerful paradigm for magnetic field-free, subwavelength optical nonreciprocity, in the mid-IR to terahertz range, with tunable splittings as large as tens of THz, as well as sensitive all-optical diagnostics of topological bands.topological materials | interactions | nonreciprocal response | Berry curvature I n electronic systems, chirality expresses the system's ability to discriminate between forward and backward propagation of electronic signals along certain directions. This technologically useful and hotly sought-after property can be achieved through the application of external magnetic fields. However, the need for strong applied fields "on-chip" brings many challenges for applications. Recently, materials exhibiting chirality in the absence of a magnetic field have started to gain prominence. These materials include metals exhibiting anomalous (1) and quantum anomalous (2-6) Hall effects, as well as nonmagnetic materials pushed out of equilibrium, where, for example, a zero-field charge Hall effect was recently demonstrated (7). In each case, zero-field chirality arises from Bloch band Berry curvature, a fundamental property of Bloch eigenstates that dramatically affects single-particle electronic motion and material responses (1,8,9).Here we show that Berry curvature can work in concert with interactions, leading to new types of collective modes in 2D topological metals, with nonvanishing Berry flux (i.e., net Berry curvature), F. In particular, F gives rise to chiral plasmonic excitations-propagating charge density waves with split dispersion for oppositely directed modes-in the absence of a magnetic field (Fig. 1). We refer to these collective modes as chiral Berry plasmons (CBPs). Notably, these chiral modes are localized to the edge of the 2D metal, even in the absence of topological edge states, and exhibit a rich phenomenology (see below).We expect CBPs to be manifested in a wide variety of magnetic and nonmagnetic materials. The former are materials that exhibit anomalous Hall effects, wherein time reversal symmetry (TRS) breaking is encoded in the Bloch band Berry curvature. The latter include a range of readily available gapped Dirac materials, e.g., transition metal dichalcoge...
