With the advent of ultra-high-precision optical spectroscopy, it is also possible to use these isotope shifts to probe physics beyond the standard model, specifically whether a fifth force exists. This Perspective outlines the progress and challenges of these studies and provides an outlook on future possibilities. This Perspective explores how the frequency shifts of atomic spectral lines between isotopes can be effective probes of physics beyond the standard model, when measured to high precision using optical spectroscopy.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"7 2","pages":"119-125"},"PeriodicalIF":44.8,"publicationDate":"2025-01-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143363099","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}

Techniques such as high-order harmonic generation (HHG) and attosecond transient absorption and reflection spectroscopy (ATAS and ATRS) provide valuable insights into sub-cycle dynamics, rendering the interaction of solids with intense laser fields a pivotal area of research. However, discrepancies in the explanation of the underlying mechanisms remain, requiring further analysis. This Perspective focuses on the relationship between the above techniques, highlighting their efficacy in probing charge dynamics induced by intense laser pulses in solid-state systems. We emphasize the importance of unified theoretical frameworks to advance our understanding of the strong-field attoscience of solids, while recognizing points of disparity between theoretical descriptions and experimental findings. By drawing attention to the complementary nature of HHG and both ATAS and ATRS, and by illustrating the key applications enabled by them, this Perspective aims to motivate stronger collaborations and concerted efforts to bridge the existing gaps between theory and experiment and propel the field forward. This Perspective explores attosecond physics in solids, focussing on high harmonic generation and attosecond transient absorption and reflection spectroscopy. Combining physical realizations and theoretical concepts is a challenge for future progress.","PeriodicalId":19024,"journal":{"name":"Nature Reviews Physics","volume":"7 1","pages":"38-49"},"PeriodicalIF":44.8,"publicationDate":"2024-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142939491","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}
