Criticality of charged AdS black holes with string clouds in boundary conformal field theory
The aim of this letter is to study the universal thermodynamics and criticality of charged AdS black holes with string cloud in the bulk and in the boundary conformal field theory. For this system, we determined the critical quantities and noticed that the free energy in the bulk exhibits swallow…

Higgs field as architect of a geodesically complete universe and agent for new physics in interiors of black holes
The Higgs boson is often compared to a small ripple on a vast, calm ocean. This “ocean” is the universal Higgs vacuum expectation value, ≈ 246 GeV, permeating all space and generating particle masses. Its remarkable uniformity reflects the large-scale nature of the universe. Here I argue that the…

Observation of renormalization group invariance in symmetry-restored nuclear lattice effective field theory
Renormalization group (RG) invariance implies that the predictions of effective field theory are independent of the momentum cutoffs introduced during regularization. Here we report the first systematic verification of RG invariance for realistic nuclear few-body systems within nuclear lattice…

Viability of A4, S4 and A5 flavour symmetries in light of the first JUNO result
We update the analysis of the viability of the lepton mixing patterns originating from A4, S4 and A5 discrete flavour symmetries and leading to predictions for the solar neutrino mixing angle, θ12. We perform a statistical analysis using as an input (i) the results of the latest global fit to…

Harvesting entanglement from the Lorentz-violating quantum field vacuum in a dipolar Bose-Einstein condensate
We theoretically propose an experimentally viable scheme to explore the transfer of nonclassical correlations from a dipolar Bose-Einstein condensate (BEC) to a pair of impurities immersed in it. Operating at ultra-low temperature, density fluctuations of the dipolar BEC emulate a vacuum field with…

Generalized relative locality and causal sets
In this paper we introduce a new general framework for the study of phenomenological quantum gravity theories (PQG). The key idea is the introduction of two different types of spacetime, an observer-independent spacetime (modeled by a smooth orientable manifold) and an observer-dependent one (which…

Different triaxial shapes in the energy spectra of 154Sm
The 154Sm nucleus, which has long been regarded as a typical quantum system exhibiting axial symmetry, has been recently suggested to exhibit a small degree of triaxiality by Otsuka et al.. This small triaxiality was recently observed through the γ decay of the 154Sm isovector giant dipole…

Machine learning the single-Λ hypernuclei with neural-network quantum states
A thorough description of baryonic system beyond first-generation quark sector is indispensable for the maturation of nuclear ab initio methods. This study pioneers the application of neural-network quantum states to hypernuclei, with trainable parameters determined by variational Monte Carlo…

Ghost-free non-local F(R) gravity compatible with ACT
We confront the ghost-free non-local F(R) gravity theories with the latest Atacama Cosmology Telescope (ACT) constraints on the spectral index of the scalar perturbations and the updated constraints of Planck/BICEP on the tensor-to-scalar ratio. After reviewing how the ghost-free non-local version…

Mesons, baryons and the confinement/deconfinement transition
We identify an observable that could operate as a probe of the quark versus hadron content of a bath of quarks and gluons at finite temperature and chemical potential. To this purpose, we relate the Polyakov and anti-Polyakov loops, which determine how energetically costly it is to bring an…

Accurate spontaneous fission half-lives from a microscopic large-scale nuclear structure model
We demonstrate that energy density functional (EDF) models for atomic nuclei can achieve a level of accuracy in describing fission properties comparable to that of more phenomenological approaches, while maintaining predictive power for nuclear ground-state observables. Using multiple BSkG…

Unified field-theoretical description of flavor and chiral oscillations
Since chirality is not conserved during free propagation, massive fermions produced through weak interactions experience chiral oscillations. For analogous reasons, neutrinos also exhibit flavor oscillations. These phenomena have been extensively studied – both individually and within a unified…

Pseudodifferential calculus in Schwinger–DeWitt formalism: UV and IR parts
We consider expansions for the kernels of operator functions of second-order minimal operators on a curved background. We show that the terms of these expansions originate in the ultraviolet or infrared regions. We propose a systematic approach to obtaining ultraviolet terms using term-by-term…

Assessing background effects in search of the chiral vortical effect in relativistic heavy-ion collisions
The search for the Chiral Vortical Effect (CVE) in relativistic heavy-ion collisions is carried out by measuring azimuthal correlators for baryon pairs such as Λ and protons. Experimental results from the ALICE collaboration show significant separations in these correlator observables between…

Entropy of matter on the Carroll geometry
Two prescriptions for the construction of Carroll geometries, the expansion of geometric variables near horizon and the expansion of metric with zero limit of the expansion parameter c (speed of light in vacuum), are known to complement each other. The entropy of an ideal gas, confined in a box and…

Non-exotic wormhoe in Rastall theory
This paper examines exact wormhole solutions within the framework of Rastall theory. Given that the Einstein field equations are altered in 3+1 dimensions under Rastall’s gravitational theory, we have explored potential solutions utilizing various forms of the equation of state. The influence of…

Symmetrized operators or modified integration measure in generalized uncertainty principle models
Many Generalized Uncertainty Principle (GUP) models modify the inner-product measure to ensure symmetric position or momentum operators. We show that an alternate approach to these GUPs is to symmetrize the operators rather than modifying the inner product. This preserves the standard momentum…

Basis representation for nuclear densities from principal component analysis
We develop an efficient method to represent nuclear densities using basis functions extracted via Principal Component Analysis (PCA). Applying PCA to densities of 75 nuclei calculated with the relativistic continuum Hartree-Bogoliubov (RCHB) theory yields an orthogonal set of components that…

Confinement by monopole loops in inhomogeneous magnetic field
We show that a generalized Polyakov mechanism can lead to confinement at weak coupling in 3+1 dimensions when the theory is placed in a non-trivial, spatially varying magnetic field background. Depending on the magnitude of the field and the length scale of its spatial variation, the “dual”…

The (higher) Hamiltonians of (generalized) trigonometric and rational Calogero-Sutherland models by MO R-matrix
By using the integrable lattice model proposed by Maulik and Okounkov, we derive the (higher) Hamiltonians of the (generalized) trigonometric Calogero-Sutherland models. Then in terms of these (higher) Hamiltonians, we further construct certain nested structures and derive the commutative operators…
