Second order critical point in QCD phase diagram
… start by arguing that the critical point of the QCD phase diagram is second order and belongs to the three dimensional Ising model universality class. Then the singular part of the equation of state is derived. The singular part and non-singular part equation of state are glued together to find …

Characterization of the Transition Region in the QCD Phase Diagram
The study of the Quantum Chromodynamics (QCD) phase diagram has been the object of great effort in the scientific community both from theory and experiment, and has been investigated from first principles through lattice simulations in the low density regime. The transition between ordinary matter …

STRONGLY INTERACTING MATTER:ANALYSIS OF QCD PHASE DIAGRAM BY THERMODYNAMIC GEOMETRY
… on the study of the Quantum Chromodynamics (QCD) phase transition, both from a phenomenological and a theoretical point of view. Three main research lines have been considered: • The study of some phenomenological topics of the phase transition has been carried out. In particular, I studied …

Probing the Nonperturbative Physics of QCD with Normalizing Flows and a moderate number of Pions
Quantum Chromodynamics (QCD) is a cornerstone of the standard model of particle physics, and the best known theory of strong nuclear interactions. The only known systematically improvable ab-initio method for accessing the nonperturbative physics of QCD is Lattice QCD is, and this thesis presents …

Strong coupling methods for lattice QCD
Lattice QCD at finite baryon density suffers from the numerical finite density sign problem. Strong coupling methods, expanding in the inverse gauge coupling, give rise to alternative representations of the partition function that can make the sign problem milder. This Habilitation discusses the …

Non-perturbative determination of Karsch Coefficients in 2 Colour QCD
Lattice QCD can be used to study the QCD phase diagram at finite temperature and zero density. Non-zero density is implemented on the lattice using the chemical potential however this gives a possibility of a complex probability which means the statistical machinery normally used breaks down. …

Efficient Monte Carlo Sampling of Lattice Field Theories
… among other things, make determination of the QCD phase diagram and calculation of the correlation functions numerically difficult. As a step towards eventually overcoming these issues, the problem of infinite variance due to the exceptional configurations in fermionic Lattice Field Theories …

Color superconducting phase of cold dense quark matter
We investigate color superconducting phases of cold quark matter at densities relevant for the interiors of compact stars. At these densities, electrically neutral and weak-equilibrated quark matter can have unequal numbers of up, down, and strange quarks. The QCD interaction favors Cooper pairs …

Gapless color superconductivity
… the "Gapless Color-Flavor Locked" (gCFL) phase, a possible new phase of dense and cold quark matter. At high enough densities, quarks interact with each other and form pairs similarly to electrons in superconductors. This phenomenon in the case of quark matter is called Color …

From quarks to cold atoms: the phases of strongly-interacting systems
In this thesis we investigate the phase structure of dense quark matter, the structure and stability of neutron and quark stars, and the phases of ultracold fermions in the presence of an artificial spin-orbit coupling. While spanning an extraordinary twenty orders of magnitude in energy scales, …

QCD Equilibrium and Dynamical Properties from Holographic Black Holes
Strongly interacting matter undergoes a crossover phase transition at high temperatures and zero net-baryon density. A key question in Quantum Chromodynamics (QCD) is whether a dense quark-gluon system exhibits critical phenomena when breaking the balance between quarks and antiquarks. Lattice QCD …

Field Theoretical Approach to the Phases of QCD
The study of the phases of Quantum Chromodynamics (QCD), at finite temperature (T) and baryon chemical potential (mu_B), is one of the biggest challenges in theoretical physics and represents a significant step towards understanding the collective behavior of the strong force. The non-perturbative …

Cold, dense quark matter
… the symmetry pattern of different quark matter phases, the collective modes associated with spontaneous chiral symmetry breaking, a possible realization of quark-hadron continuity in the color-flavor locked (CFL) quark superfluid, and the implications of these issues to quark matter equations of …
