Although the finiteness of the cavity, being bounded by reflecting mirrors, endows the cavity photons with an effective mass, they become massless at the continuous phase-transition point. We consider the matter part coming from the fermions hopping on a honeycomb lattice near half-filling, featuring doped Dirac cones at two sets of inequivalent valleys. This choice is dictated by the presence of a fermion–boson interaction vertex, which can give rise to Landau damping of the critical bosons, eventually leading to an NFL phase for the fermions. To set up the quantum effective action, we identify the hot-spots of the generically anisotropic (trigonally-warped) Fermi surfaces, which give the sets of points having parallel/antiparallel tangent vectors. The cavity photons act as charge density wave (CDW) order parameters, connecting pairs of hot-spots belonging to the Fermi surface of a single valley. With these ingredients, we set upon identifying NFL phases, using the tools of dimensional regularization and renormalization-group-flow equations. Our final results indicate that stable NFL phases exist in the low-energy limit, for the projections of the flows along the CDW coupling constant.</div></div>","PeriodicalId":8249,"journal":{"name":"Annals of Physics","volume":"474 ","pages":"Article 169925"},"PeriodicalIF":3.0,"publicationDate":"2025-01-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143097048","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}

This study is the first to investigate quantum tunneling through a fractal geometric Dirac comb potential.

The notion of cosmic dark energy may serve as a potential mechanism to counteract the relativistic gravitational collapse of stellar distributions into singularities. Dark energy plays a vital role in shaping the cosmos on the largest scales, as it is the driving force behind the observed accelerated expansion. Therefore, it is reasonable to think that dark energy influences the kinematics of gravitationally bound stellar structures (Sakti and Sulaksono, 2021) [65]. Motivated by this, we introduce a self-gravitating stellar system model under the influence of dark energy, which incorporates both dark and ordinary matter. The model assumes a direct proportionality between the dark energy density and the perfect fluid density. We will then analyze the astrophysical features, including the regularity of the metric variables, density, pressure, mass–radius relationship, stability, dark energy parameters, and equilibrium conditions associated with the model. The model is promising due to its adherence to energy conditions and lack of a central singularity. By examining a mass–radius diagram, we have found the maximum mass limit for this type of star. Our results show that our suggested model corresponds to a feasible and physically realistic star structure that satisfies all stability criteria.</div></div>","PeriodicalId":8249,"journal":{"name":"Annals of Physics","volume":"474 ","pages":"Article 169921"},"PeriodicalIF":3.0,"publicationDate":"2025-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143097022","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}
