The cooling laser beams comprised the incident, retroreflected, and four diagonally diffracted beams at an angle of 50° with respect to the normal direction of the grating surface. The intensity of the retroreflected beam was carefully adjusted to balance the radiation forces acting on the atoms. A significant number of cold atoms (7.0 × 106) were captured, in spite of the difficulty in a magneto-optical trap of cesium atoms, using nonorthogonal cooling beams owing to the high nuclear spin. The significance of the retroreflected beam in the trapping process was highlighted when the intensity of the retroreflected beam was reduced, resulting in the absence of trapped atoms. Notably, the cold atom cloud was generated near the edge of the region, where all the cooling beams were overlapped. The phenomenon is explained by the numerical calculations of the radiation forces considering all the Zeeman sublevels in the cooling transition and the Gaussian intensity profile of the incident beam.","PeriodicalId":8094,"journal":{"name":"Applied Physics Letters","volume":"12 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319437","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

In this work, 0.5 mol. % La-(1 − x)PMN-xPT transparent ceramics with different solid solution ratios (i.e., x = 0.10, 0.15, 0.20, 0.25) were fabricated to study the temperature-dependent electro-optic behaviors. Two distinct temperature dependencies are revealed: for 0.85PMN-0.15PT and 0.90PMN-0.10PT, the measured electro-optic coefficient decreases with increasing temperature, while for 0.75PMN-0.25PT and 0.80PMN-0.20PT, the electro-optic coefficient first increases and then decreases rapidly with the increase in temperature. Based on the temperature-dependent dielectric, ferroelectricity, x-ray diffraction, and piezoresponse domain image analysis, the ferroelectric–ferroelectric phase transition is suggested to play a dominant role, with the ferroelectric state to relaxor state transition providing an auxiliary enhancement. This study provides valuable insights into understanding temperature-dependent electro-optic behaviors and should be instructive for the design and optimization of advanced electro-optic devices.","PeriodicalId":8094,"journal":{"name":"Applied Physics Letters","volume":"11 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Bonded heterostructures offer distinct advantages over conventional two-dimensional (2D) monolayers by synergistically stabilizing lattice frameworks through interfacial interactions. 2D hybrid lattices composed of honeycomb and kagome structures have garnered significant attention due to their unique geometries and tailored electronic states. Herein, via first-principles calculations, we propose a strongly bonded β12-borophene (β12-B)/hybrid honeycomb–kagome silicene (hhk-Si) heterostructure as a high-performance anode for lithium/sodium-ion batteries (LIBs/SIBs). This bonded configuration exhibits superior structural stability compared to van der Waals counterparts, as evidenced by machine learning-accelerated ab initio molecular dynamics simulations spanning an extended 100 ps timeframe. The heterostructure demonstrates intrinsic structural robustness during multi-ion intercalation, coupled with stable adsorption sites featuring ultralow diffusion barriers (Li: 0.35 eV; Na: 0.20 eV). Notably, the predicted maximum sodium storage capacity reaches 1823 mAh/g, outperforming both monolayers and most 2D heterostructures. These findings suggest that the proposed β12-B/hhk-Si is a promising anode for SIBs and paves the way for kagome–honeycomb hybrid lattices in energy storage applications.","PeriodicalId":8094,"journal":{"name":"Applied Physics Letters","volume":"600 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319575","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}

Argon was used as a quasi-hydrostatic pressure-transmitting medium. The phase transition from low-density β-Ga2O3 to high-density α-Ga2O3 was observed, beginning at approximately 20.57 GPa and completing in the pressure range of 39.70–42.29 GPa. The α-Ga2O3 phase remains stable up to approximately 80 GPa at ambient temperature, and the β-to-α phase transition is an irreversible reconstructive phase transition. A third-order Birch-Murnaghan equation of state fit to the unit-cell volume as a function of pressure yielded a zero-pressure bulk modulus B0 of 200.2(22) GPa for β-Ga2O3, with a pressure derivative B0′ of 3.0(11) GPa. For α-Ga2O3, the fit gave B0 = 354.8(43) GPa and B0′= 2.2(8) GPa. When B0′ was fixed at 4, a re-fit of the experimental data provided B0 = 267.9(7) GPa for the α-phase, which is higher than B0 = 182.6(7) GPa for the β-phase, indicating that α-Ga2O3 exhibits greater resistance to compression. Based on high-pressure experimental results for β-Ga2O3 at different temperatures, the phase boundary for the β-to-α transition, exhibiting a negative Clapeyron slope, is presented in this study. With increasing temperature, the onset pressure of the β-to-α transition gradually decreases, and the phase transition hysteresis effect weakens.","PeriodicalId":8094,"journal":{"name":"Applied Physics Letters","volume":"44 1","pages":""},"PeriodicalIF":4.0,"publicationDate":"2025-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144319489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
