The stationary field equation reduces to an inverse-square Schrödinger-type problem with a quadratic spectral parameter. By imposing a perfectly absorbing boundary condition at the singularity, the Hermitian inverse-square anomaly is naturally continued to an open dissipative system, where the geometric tower of bound states is reinterpreted as a hierarchy of resonant decay modes. We present an explicit analytical derivation showing that the resonance decay rates obey a universal log-periodic scaling relation determined solely by the anomalous scaling exponent and robust against generic subleading perturbations. The construction establishes a direct connection between self-adjoint boundary conditions and their non-Hermitian absorbing counterparts through analytic continuation of the boundary phase, demonstrating that the underlying discrete scale invariance survives in the presence of irreversible absorption. The resulting framework provides a minimal, exactly solvable laboratory for studying quantum scale anomalies, boundary-condition-induced non-Hermiticity, and quantized dissipation in relativistic open quantum systems.","PeriodicalId":20162,"journal":{"name":"Physics Letters B","volume":"35 1","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148691445","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 study, we investigate the dynamics of charged particles orbiting magnetized black holes in a noncommutative (NC) geometry. We study the circular motion and oscillations of charged particles orbiting a black hole in the presence of a magnetic field, focusing on their applications to QPOs. First, we obtain solutions to the Maxwell equations for the orthonormal components of the magnetic field around black holes in the radial and angular directions, and analyze their dependence on the NC parameter and magnetic interactions. We analyze the effective potential, specific angular momentum, energy, and innermost stable circular orbits (ISCOs) of charged particles to demonstrate how the black hole spacetime, with magnetic interaction and NC parameters, affects particle dynamics. Then, we calculate the Keplerian, radial, and vertical epicyclic frequencies, providing insight into the orbital and oscillatory behavior of particles near the black hole. Furthermore, we investigate twin-peak QPOs using the relativistic precession (RP), warped disc (WD), and epicyclic resonance (ER) models and compare the main results with those of the standard Schwarzschild limit. Finally, we employ Monte Carlo Markov Chain (MCMC) simulations to obtain constraint values for black hole mass, the NC, and magnetic interaction parameters, using QPO frequency data observed in microquasars (XTE J1550-564, GRO J1655-40, GRS 1915+105), intermediate-mass (M82 X-1), and supermassive (SgrA*) BHs. Our findings may provide valuable insights into understanding the combined effects of NC spacetime and electromagnetic interactions around black holes on astrophysical observations of QPOs and on testing gravity theories in the strong-gravity regime.","PeriodicalId":20162,"journal":{"name":"Physics Letters B","volume":"21 1","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-08-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148691443","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}

{"title":"First Law for Nonsingular Black Holes in 2D Dilaton Gravity","authors":"Peng Yu, Yuan Zhong","doi":"10.1016/j.physletb.2026.140826","DOIUrl":"https://doi.org/10.1016/j.physletb.2026.140826","url":null,"abstract":"A central issue in the thermodynamics of nonsingular black holes is the apparent violation of the first law. In this work, we use 2D dilaton gravity as a simple theoretical setting to study this issue. We systematically construct a broad class of nonsingular black hole solutions with metric function <mml:math altimg=\"si1.svg\"><mml:mrow><mml:mi>A</mml:mi><mml:mo>(</mml:mo><mml:mi>x</mml:mi><mml:mo>)</mml:mo><mml:mo>=</mml:mo><mml:mi>f</mml:mi><mml:mo>(</mml:mo><mml:mi>x</mml:mi><mml:mo>)</mml:mo><mml:mo>+</mml:mo><mml:mi>c</mml:mi></mml:mrow></mml:math>, through a procedure that is considerably simpler than in higher-dimensional theories. Using the Iyer-Wald covariant phase space formalism, we derive the correct energy formula and establish a consistent first law for this entire class of solutions. The apparent violation of the first law in a previous work arises because the energy used therein is not the Hamiltonian conjugate to the fixed time-translation generator adopted. Under the boundary conditions and normalization convention specified in the present work, the Iyer-Wald Hamiltonian energy is <mml:math altimg=\"si2.svg\"><mml:mrow><mml:mi>E</mml:mi><mml:mo linebreak=\"goodbreak\">=</mml:mo><mml:mo>−</mml:mo><mml:mfrac><mml:mi>c</mml:mi><mml:mn>2</mml:mn></mml:mfrac></mml:mrow></mml:math>, and the first law is restored. Moreover, the energy formula agrees with the Casimir function in 2D dilaton gravity, thus confirming its interpretation as the physical black hole energy. Our results clarify the correct first law for 2D nonsingular black holes and may provide insights into the first law of nonsingular black holes in higher dimensions.","PeriodicalId":20162,"journal":{"name":"Physics Letters B","volume":"38 1","pages":""},"PeriodicalIF":4.4,"publicationDate":"2026-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148691448","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}
