Gaussian black holes are a significant category of regular black holes, representing a set of spherically symmetric static solutions derived from Einstein’s equations in the presence of the cosmological constant. The research explores the thermodynamic properties of these black holes within the framework of pure quadratic modified gravity. By applying the laws of black hole thermodynamics, various quantities such as Hawking temperature, equation of state, and Gibbs free energy are analyzed. Moreover, the study examines the phase transitions of such black holes, accompanied by graphical representations of the relevant quantities. Based on the critical points identified, the stability and phase transition behavior of the system are evaluated. The investigation also delves into the assessment of stability, instability, and the Swallowtail behavior exhibited by the system. Also the presence of a discontinuity in the heat capacity leads to a phase transition within the system, reminiscent of Van der Waals-like phase transitions observed between small-large black holes.</div></div>","PeriodicalId":8249,"journal":{"name":"Annals of Physics","volume":"473 ","pages":"Article 169910"},"PeriodicalIF":3.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143149603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}

We show that electromagnetic radiation imparts an electric potential energy to an electron which is proportional to the product of the angular frequency of radiation field, magnetic flux and the magnitude of electron charge. While assuming magnetic flux quantisation and phasor representation of electromagnetic fields, the mathematical expression of the energy of a photon, as well as Planck’s constant, have been derived using the principles of classical electromagnetism. It implies that the particle like behaviour of electromagnetic radiation under interaction with matter emerges as a consequence of magnetic flux quantisation and discrete energy transfer to charges.</div></div>","PeriodicalId":8249,"journal":{"name":"Annals of Physics","volume":"473 ","pages":"Article 169893"},"PeriodicalIF":3.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143149606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"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}
