Magnetic dual chiral density wave: A candidate quark matter phase for the interior of neutron stars

EJ Ferrer, V de la Incera - Universe, 2021 - mdpi.com
In this review, we discuss the physical characteristics of the magnetic dual chiral density
wave (MDCDW) phase of dense quark matter and argue why it is a promising candidate for …

Analogy between rotation and density for Dirac fermions in a magnetic field

HL Chen, K Fukushima, XG Huang, K Mameda - Physical Review D, 2016 - APS
We analyze the energy spectra of Dirac fermions in the presence of rotation and magnetic
field. We find that the Landau degeneracy is resolved by rotation. A drastic change in the …

Inhomogeneous chiral symmetry breaking in dense neutron-star matter

M Buballa, S Carignano - The European Physical Journal A, 2016 - Springer
An increasing number of model results suggests that chiral symmetry is broken
inhomogeneously in a certain window at intermediate densities in the QCD phase diagram …

Dual chiral density wave induced oscillating Casimir effect

D Fujii, K Nakayama, K Suzuki - Physical Review D, 2024 - APS
The Casimir effect is known to be induced from photon fields confined by a small volume,
and also its fermionic counterpart has been predicted in a wide range of quantum systems …

Scrutinizing the pion condensed phase

S Carignano, L Lepori, A Mammarella… - The European Physical …, 2017 - Springer
When the isospin chemical potential exceeds the pion mass, charged pions condense in the
zero-momentum state forming a superfluid. Chiral perturbation theory provides a very …

Phase transitions and resilience of the magnetic dual chiral density wave phase at finite temperature and density

W Gyory, V de la Incera - Physical Review D, 2022 - APS
We study the phase transitions at finite temperature and density of the magnetic dual chiral
density wave (MDCDW) phase. This spatially inhomogeneous phase emerges in cold …

Chiral symmetry breaking and phase diagram of dual chiral density wave in a rotating quark matter

SMA Tabatabaee Mehr - Physical Review D, 2023 - APS
We study the inhomogeneous phase of a two-flavor quark matter under rotation at finite
temperature and density using the Nambu-Jona-Lasinio model. To do this, we consider the …

How transverse thermal fluctuations disorder a condensate of chiral spirals into a quantum spin liquid

RD Pisarski, AM Tsvelik, S Valgushev - Physical Review D, 2020 - APS
For a scalar theory with a global O (N) symmetry, when N= 2 a spatially inhomogeneous
condensate arises when the term in the Lagrangian with two spatial derivatives has a …

Tidal deformability of strange stars and the GW170817 event

O Lourenço, CH Lenzi, M Dutra, EJ Ferrer… - Physical Review D, 2021 - APS
In this work we consider strange stars formed by quark matter in the color-flavor-locked
(CFL) phase of color superconductivity. The CFL phase is described by a Nambu-Jona …

Axion-polaritons in quark stars: a possible solution to the missing pulsar problem

EJ Ferrer, V Incera - The European Physical Journal C, 2024 - Springer
This paper proposes an alternative mechanism to solve the so-called missing pulsar
problem, a standing paradox between the theoretical expectations about the number of …
