Phases of hadron-quark matter in (Proto) neutron stars
(Molecular Diversity Preservation International, 2019-07)
In the first part of this paper, we investigate the possible existence of a structured hadron-quark mixed phase in the cores of neutron stars. This phase, referred to as the hadron-quark pasta phase, consists of spherical ...
Heavy quark collisional energy loss in the quark-gluon plasma including finite relaxation time
(American Physical Society, 2014-07)
In this paper, we calculate the soft-collisional energy loss of heavy quarks traversing the viscous quarkgluon plasma including the effects of a finite relaxation time τπ on the energy loss. We find that the collisional ...
Quark matter and meson properties in a Nonlocal SU(3) chiral quark model at finite temperature
(SP MAIK Nauka/Interperiodica, 2012-06)
We study the finite temperature behavior of light scalar and pseudoscalar meson properties in the context of a three-flavor nonlocal chiral quark model. The model includes mixing with active strangeness degrees of freedom, ...
Neutrino emissivity in the quark-hadron mixed phase
(MDPI Multidisciplinary Digital Publishing Institute, 2018-05)
In this work we investigate the effect a crystalline quark-hadron mixed phase can have on the neutrino emissivity from the cores of neutron stars. To this end we use relativistic mean-field equations of state to model ...
Role of heavy quarks in light hadron fragmentation
(American Physical Society, 2016-08)
We investigate the role of heavy quarks in the production of light flavored hadrons and in the determination of the corresponding nonperturbative hadronization probabilities. We define a general mass variable flavor number ...
1/Nc expansion and the spin-flavor structure of the quark interaction in the constituent quark model
(American Physical Society, 2010-12)
We study the hierarchy of the coefficients in the 1/Nc expansion for the negative parity L=1 excited baryons from the perspective of the constituent quark model. This is related to the problem of determining the spin-flavor ...

Quark deconfinement in high-mass neutron stars
(American Physical Society, 2014-01)
In this paper, we explore whether or not quark deconfinement may occur in high-mass neutron stars such as J1614 - 2230 (1.97±0.04M) and J0348 + 0432 (2.01±0.04M). Our study is based on a nonlocal extension of the SU(3) ...
Surface tension of hot and dense quark matter under strong magnetic fields
(American Physical Society, 2019-03)
We study the surface tension of hot, highly magnetized three-flavor quark matter droplets, focusing specifically on the thermodynamic conditions prevailing in neutron stars, hot lepton-rich protoneutron stars, and neutron ...
