Fate of the topological susceptibility in two-color dense QCD
Journal of High Energy Physics, 2023 We explore the topological susceptibility at finite quark chemical potential and zero temperature in two-color QCD (QC2D) with two flavors. Through the Ward-Takahashi identities of QC2D, we find that the topological susceptibility in the vacuum solely ...

Non-vanishing zero-temperature normal density in holographic superfluids
, 2020 International audienceThe low energy and finite temperature excitations of a d + 1-dimensional system exhibiting superfluidity are well described by a hydrodynamic model with two fluid flows: a normal flow and a superfluid flow.

Journal of High Energy Physics, 2022 The phase diagram on the θ-T plane in four dimensional SU(3) Yang-Mills theory is explored. We revisit the θ dependence of the deconfinement transition temperature, T c (θ), on the lattice through the constraint effective potential for Polyakov loop. The

Holographic correlation functions at finite density and/or finite temperature [PDF]
, 2022 We calculate holographically one and two-point functions of scalar operators at finite density and/or finite temperature. In the case of finite density and zero temperature we argue that only scalar operators can have non-zero VEVs.

Frontiers in Energy Research, 2022 Porcelain insulators play a vital role for the safety and stability operations of electric systems. In a strong electric field, these insulators easily break down and become zero resistance insulators, which impacts the safety and stability operations of

The instanton liquid and the axion [PDF]
, 2010 The ultimate goal of this thesis is to improve our understanding of the cosmology of axions. Axions couple to QCD instantons and these non-perturbative effects are modeled within the framework of the interacting instanton liquid model (IILM).

Pion screening mass at finite chemical potential
Journal of High Energy Physics, 2023 We present a method to compute the responses of meson screening masses to the chemical potential by Taylor expanding the correlator using lattice QCD simulation. We start by comparing the free theory lattice results with the analytical expression.

Equation of state in two-, three-, and four-color QCD at nonzero temperature and density
Physical Review D, 2015 We calculate the equation of state at non-zero temperature and density from first principles in two-, three- and four-color QCD with two fermion flavors in the fundamental and two-index, antisymmetric representation. By matching low-energy results (from a `hadron resonance gas') to high-energy results from (resummed) perturbative QCD, we obtain results

Journal of High Energy PhysicsIn our previous paper [1], we found that the complex Langevin (CL) method works for QCD at finite density on the 163 × 32 lattice in the low-temperature high-density regime within the range μ/T = 1.6 – 9.6 with μ and T being the quark chemical potential ...
