Here we demonstrate giant phonon rectification in solid-state \"phonon Tesla valves\", inspired by Nikola Tesla's fluidic one-way valve but governed by fundamentally different transport physics. Using ab initio Boltzmann transport simulations with full scattering matrices, we show that hydrodynamic phonon transport in graphite coupled with asymmetric valve geometry produces strong forward-backward contrast in phonon relaxation. Single-stage devices achieve rectification ratios of up to approximately 8, while multistage configurations reach ratios of approximately 16, far exceeding those of prior thermal diodes. The rectification mechanism originates from asymmetric relaxation of nonequilibrium phonons at diffusive boundaries, in contrast to inertia-driven fluid Tesla valves. These results examine the performance limits of phonon Tesla valves and establish a platform for directional heat control and highlight the unique potential of hydrodynamic phonons for thermal information processing and energy technologies.","PeriodicalId":20109,"journal":{"name":"Physical Review Applied","volume":"25 5","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13353512/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148423294","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using a femtosecond pump pulse above the Mn K edge to generate simultaneous 1s core holes, and a second-color tunable seed pulse to initiate the stimulated emission process, we were able to enhance individual lines within the Kα 1 emission. This approach allows to resolve the fine multiplet features that are obscured by lifetime broadening in conventional (spontaneous) Mn Kα XES. The work builds on our previous observation that S-XES from Mn(II) and Mn(VII) complexes pumped at high intensities can exhibit stimulated emission without sacrificing the chemical sensitivity to oxidation states. This technique opens the door to controlled high-resolution electronic structure spectroscopy in transition-metal complexes beyond the core-hole lifetime, with potential applications in catalysis, inorganic chemistry, and materials science.","PeriodicalId":20109,"journal":{"name":"Physical Review Applied","volume":"25 5","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13465953/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148726169","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
