The standard model of the universe, λCDM, is based on the FLRW metric with a flat coordinate space and the Friedmann equations. The cosmological constant λ provides the cancellation of the matter field contributions in the flat (Minkowski) space, as was proposed long ago in 1967 by Zeldovich. The dynamical dark energy appears on the surface of the vacuum energy of matter fields at the flat...

Understanding the non-perturbative properties of the quark-gluon plasma (QGP) formed in ultrarelativistic heavy-ion collisions remains a central challenge in QCD phenomenology. Conventional quasi-particle approaches rely on analytic parametrizations that often fail to capture the complex thermal structure of the medium, particularly near the deconfinement crossover region. To address this, we...

Neutron stars (NSs) are the superdense objects with exceptionally strong gravitational fields, providing an ideal laboratory for exploring general relativity (GR) in the high-curvature regime. They also open up exciting possibilities for probing new gravitational physics beyond the established framework of GR. Thus, investigating modified theories of gravity in the context of superdense stars...

In the presence of the chiral symmetry, the vector and axial-vector meson channels are expected to be degenerate. With Generation 2 and Generation 2L FASTSUM lattice gauge field ensembles at non-zero temperature, the FASTSUM collaboration studied the mesonic/baryonic correlator ratios at finite temperature. They also studied the effect of small baryon chemical potential on the mesonic...

The impact of density and temperature on pseudoscalar $D_s$ and $B_s$ mesons is analyzed within an isospin-asymmetric resonance matter using the chiral SU(3) model combined with a QCD sum-rule approach. The quark and gluon condensates obtained from the chiral SU(3) model serve as input to the QCD sum rule approach, enabling the calculation of in-medium masses of $D_s$ and $B_s$ mesons. These...

We investigate the $p_{\rm T}$-differential radial flow observable $v_0(p_{\rm T})$ in Au+Au collisions at $\sqrt{s_{\rm NN}} = 200$ GeV using AMPT model in its String Melting (SM) configuration. For inclusive charged hadrons, the AMPT-SM framework, that includes partonic dynamics, reproduces three hallmarks of genuine collective behavior: (i) long-range pseudorapidity correlations, (ii)...

The European Muon Collaboration (EMC) effect indicates that the nuclear medium is not merely a passive background but plays an active role in shaping the internal structure of nucleons, as the structure function of nucleons inside the nuclei comes out to be different from that of free nucleons. Motivated by the EMC effect, the present work focuses on the study of internal quark dynamics of the...

The Schwinger effect is a nonperturbative manifestation of vacuum instability and cannot be captured by a finite-order expansion in the external electric field. Its standard treatment already involves an appropriate resummation. For example, the vacuum decay rate is obtained in the in-out formalism from the imaginary part of the one-loop effective action, which compactly represents the sum of...

We construct an equation of state describing cold and dense matter in the core of neutron stars which includes an admixture of fermionic dark matter and incorporates nucleon effective masses derived from the relativistic Brueckner-Hartree-Fock (BHF) many-body approach within a relativistic mean-field model. Such a BHF-informed mixed-model approach increases stellar compactness, with...

We investigate the impact of dark matter on the structure and deformation of magnetars. We adopt a perturbative approach to model magnetic-field-induced deformation and assume that dark matter interacts with hadronic matter only through gravity. Under the assumption that dark matter is significantly softer than hadronic matter, we find that magnetic fields can indirectly influence the dark...

We investigate the pole structure of the (T_{cs}) resonance in a coupled-channel quark model. The model space is separated into a compact four-quark sector (P) and a two-meson continuum sector (Q={DK,D^\ast K^\ast}). Compact seed states are calculated using constituent-quark Hamiltonians with two-body one-gluon-exchange interactions and possible instanton-induced or three-body...

Neutron stars provide a unique astrophysical laboratory for probing dark matter under extreme density and strong gravity. Motivated by dark-sector interpretations of the neutron lifetime anomaly, we investigate neutron-to-dark-matter conversion in dense neutron-star matter and its impact on the equation of state and stellar observables.
We model baryonic matter within a non-linear...

We present a hybrid classical quantum approach for simulating lattice QCD in the strong coupling regime using a quantum annealer. In this limit, lattice QCD can be reformulated in terms of color singlet degrees of freedom monomers subject to local constraints arising from Grassmann integration. This dual representation eliminates the gauge fields while retaining essential non perturbative...

The QGP(Quark-Gluon Plasma) and the QCD phase transition from/to the hadronic phase are one of the hottest topics in high energy nuclear physics. In particular, the dense matter study via nuclei collisions at $\sqrt{s_\mathrm{NN}} \sim 5 - 10 \, \mathrm{GeV}$ is expected to bring more detailed information on the 1st order phase transition, whereas the hot matter study through nuclei collisions...

Much of the physics in the cold-dense region in the QCD phase diagrams are characterised by the formation of Cooper pairs on the Fermi surface. In two-flavour symmetric quark matter, a phase transition is expected to occur into the two-flavour colour superconducting (2SC) phase. A key feature of this phase is that certain quarks remain ungapped due to repulsive colour-symmetric interactions....

We study the possible existence of the hexaquark H particle (uuddss) in neutron stars. Within the Chromomagnetic Interaction framework, the flavor-singlet H exhibits a mass of 2212.7 MeV. Using the relativistic mean-field model, we explore how H particle couplings influence neutron star structure. Our results indicate that H particles could persist as stable constituents, reducing the maximum...

This work investigates heavy quark dynamics within the quark-gluon plasma (QGP) by incorporating memory effects through a generalized Langevin equation. We model time-correlated thermal noise with a power-law decay using a fractional differential equation based on the Caputo fractional derivative of order parameter (\nu ). To calculate the impact of memory, we systematically evaluate the...

Recent neutron-star observations and equation-of-state studies incorporating ab initio QCD constraints are placing increasingly stringent constraints on dense matter. In this context, homogeneous color superconductivity has attracted renewed phenomenological interest and has been actively studied in recent years.
On the other hand, inhomogeneous phases remain relatively less explored....

We study the effects of non-zero isospin density on the topological susceptibility in lattice simulations with $N_f = 2 + 1$ flavors of improved staggered quarks at multiple lattice spacings. To reduce lattice artifacts, we employ a generalization of the eigenvalue reweighting technique known from vanishing densities to non-zero isospin chemical potentials, using the (massive) singular values...
