    Starting from the quadratic expansion in the photon fields of non-linear electrodynamics Lagrangian model, we study relevant vacuum properties in a scenario involving the propagation of a photon probe in the presence of a background constant magnetic field.

    We study the structure of the QCD vacuum, and its relation with the special gluonic configurations. These non-trivial topological configurations so called instantons. The spontaneous chiral symmetry breaking via QCD axial anomlay will be discuss. We propose an effective model starting of the Maxwell-Chern-Simons theory, where a chiral current generation will be calculated associated to an...

    We investigate the influence of the equation-of-state (EoS) of strongly interacting hadronic and partonic matter created in heavy-ion collisions on the light cluster and hypernuclei production within the Parton-Hadron-Quantum-Molecular Dynamics (PHQMD) microscopic transport approach (PHQMD) [1-5]. The PHQMD is a microscopic n-body transport model based on the QMD propagation of the baryonic...

    We present results on the production of light clusters in heavy ion collisions. We show that a coalescence approach yields a good description of the available data over the whole energy range. We extend our analysis to anti-deuterons (currently of interest due to the AMS measurement ni relation to dark matter) and strange hyper-clusters which are relevant for our understanding of the structure...

    The vector $U$-bosons, or so-called 'dark photons', are potential candidates for dark matter mediators. They are expected to interact with standard matter via a 'vector portal' due to the $U(1)-U(1)^\prime$ symmetry group mixing, which may make them detectable in particle and heavy-ion experiments. Although there has been no confirmed observation of dark photons, detailed analyses of various...

    Correlations between the harmonic flow coefficients v1, v2, v3 and v4 of nucleons in peripheral Au+Au collisions at 1.23A GeV are investigated with the Ultra-relativistic Quantum Molecular Dynamics model employing different Equations-of-State (hard Skyrme, soft Skyrme, Chiral-Mean-Field). Using an event-by-event selection based on the final state it is shown that the triangular flow changes...

    We investigate heavy quark mass near the phase transition by combining the statistical model on hadronic side and the quasi-particle model on partonic side. We find heavy quark mass much larger than the bare mass in QCD Lagrangian. This massive heavy quark is supported by the thermal production of heavy quark in heavy-ion collision experiments.

    We provide the first analysis of the variable X-ray sky obtained with eROSITA using standard normalized excess variance, maximum amplitude variability tests, and Bayesian tests to constrain the variability of different object classes.

    The equation of state of strongly interacting matter is explored by
    earthbound experiments, by studying neutron star properties and most
    recently also by
    analyzing gravitational waves from neutron star mergers. I will discuss
    in the contribution the situation for earthbound experiments, how one
    can get information
    about the equation of state, what is needed to extract this...

    We study the possible generation of relativistic jets induced by a chiral imbalance in a strongly magnetized electron–positron plasma in magnetospheres of spinning black holes. Stationary, axisymmetric, force–free magnetospheres Kerr black holes are analyzed. We explore the chiral symmetry breaking induced by longitudinal photons as a possible condition for the creation of relativistic jets....

    We investigate the emission of gravitational waves from spheroidal, magnetized strange stars in two scenarios: an isolated, slowly rotating star and a binary system. For the isolated star, we compute the quadrupole moment and the amplitude of the gravitational waves that may be emitted. In the case of the binary system, we determine the tidal deformability by simultaneously solving the...

    A low-energy model is built to study systems such as Dirac/Weyl semimetals, according to statistical quantum electrodynamics formalism. We report that the introduction of a pseudoscalar, associated to longitudinal photons propagating along a magnetic field B, could transforms a Dirac semimetal into a Weyl semimetal with a pair of Weyl nodes for each point of Dirac. The nodes are separated by a...

    Nowadays the neutrino oscillations is one of the main problems in particle physics. The problem of the mass, which is an essential condition to describe the oscillation of flavors is not clear. Experimental evidence suggests the possibility of a new physics beyond standard model where the neutrino oscillations can be understood. On the other hand, the spontaneous breaking of Lorentz symmetry,...

    We evaluate the feasibility of Bose-Einstein condensate stars (BECS) as models for the interior of neutron stars (NSs). BECS are compact objects composed of bosons, formed through the spin-parallel pairing of neutrons. Here, we utilize the astronomical data from GW170817, XMMU J173203.3-344518 (the lightest NS known), and a novel lower limit on NS core heat capacity to scrutinize the...

    In relativistic heavy ion collisions, a deconfined QCD matter called quark-gluon plasma (QGP) is produced. Heavy quarks, due to their large masses, are mostly produced in the early stages of heavy ion collisions and experience the whole evolution of the produced matter. So it can be a nice probe to the QGP. Meanwhile, the heavy quark energy loss, hadronization, quarkonium evolution and...

    The energy and centrality dependence of the kaon resonance ratio $(K^{*0}+\bar{K}^{*0})/(K^+ + K^-)$ is explored in the RHIC-BES and CBM-FAIR energy regime. To this aim, the Ultra-relativistic Quantum Molecular Dynamics (UrQMD) model is employed to simulate reconstructable $K^{*}$ resonances in Au+Au and p+p collisions from $\sqrt{s_{\text{NN}}}=3-39$ GeV. We obtain a good description of the...

    The work explores the emergence of space-time from tensor networks. Following a known prescription we construct a bulk 2D Ising model, whose free energy captures the partition function of a random tensor network, reproducing the entanglement entropy of particular boundary theories. We assume the Ryu-Takayanagi formula, and the Ising model couplings are obtained with a machine learning...

    Hypercompact HII regions (HC) are regions of ionized gas associated with the earliest stages of high-mass star formation. With the aim of better understanding their characteristics, we have carried out a study of five candidates for HC HII regions. For this, we performed observations with the Jansky Very Large Array (JVLA) at 2 and 6 cm, with an angular resolution of ∼0.900 . As a result, we...

We reproduce the low temperature behavior of the boson gas characterized by two plateus of specific heat the first one at 1/2, the reduction on one dimensional gas due to the strong magnetic field provokes that all the bosons are in the...
