The evolution of their spatio-temporal dynamics is of particular interest. In the present work, the spatio-temporal evolution of ultrashort Laguerre Gauss (LG) vortex with power exponential spectrum, also called power exponential (PE) pulse is numerically explored, in dispersive and nonlinear media. The evolution of space-time non-separable ultrashort vortex pulse is specifically addressed. The study reveals the asymmetric spatio-temporal evolution and splitting in the spatio-temporal plane. Compression at the trailing edge of the pulse is observed with increase in the strength of the nonlinearity. The study further reveals that the temporal, spectral, and chirp evolution patterns of the pulse vary uniquely across different spatial regions and these variations depend upon the strength of nonlinearity and propagation distance. In weak nonlinear regime, a redshift in the spectrum is observed as one moves radially outward from the bright caustic of the ultrashort LG vortex, while a blueshifted spectrum emerges as one approaches the phase singularity. Interestingly, as the pulse furthers in the medium, nonlinearity induced spectral shift is witnessed and with stronger nonlinearity, a complex spectral evolution is observed.</p>","PeriodicalId":7896,"journal":{"name":"Annalen der Physik","volume":"537 5","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143939681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"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}

To enhance the HR performance of a square molten salt absorber tube (AE) at low <i>Re</i>, a wavy-tape insert (WET) is first introduced. The performance of square molten salt AE with WET is evaluated under various operational conditions and structural parameters. Results show that the WET generates a substantial swirling flow in the square molten salt AE, which promotes the fluid mixing and then enhances HR. Compared to a smooth SAT, the friction factor (<i>f</i>) for square molten salt AE with WET increases by at least 2.55 times, whereas the Nusselt number (<i>Nu</i>) increases by 1.11–5.77 times. Additionally, the entropy generation rate (EGR) and exergy loss (EL) decrease by 35.54%–82.65% and 43.43%–84.61%, respectively. Furthermore, the transport efficiency of thermal energy (TETE) and exergy efficiency (EE) increase by 6.58%–26.24% and 10.26%–46.13%, respectively.
