QCD at finite baryon density: nucleon droplets and color superconductivity
- M. Alford, K. Rajagopal, F. Wilczek
- Physics
- 19 November 1997
Abstract We use a variational procedure to study finite density QCD in an approximation in which the interaction between quarks is modelled by that induced by instantons. We find that uniform states… Expand
Color flavor locking and chiral symmetry breaking in high density QCD
- M. Alford, K. Rajagopal, F. Wilczek
- Physics
- 27 April 1998
Abstract We propose a symmetry breaking scheme for QCD with three massless quarks at high baryon density wherein the color and flavor SU(3) color × SU(3) L × SU(3) R symmetries are broken down to the… Expand
Solution of the complex action problem in the Potts model for dense QCD ? ? This work is supported i
- M. Alford, S. Chandrasekharan, J. Cox, U. Wiese
- Physics
- 19 January 2001
Monte Carlo simulations of lattice QCD at non-zero baryon chemical potential μ suffer from the notorious complex action problem. We consider QCD with static quarks coupled to a large chemical… Expand
Magnetic fields within color superconducting neutron star cores
- M. Alford, J. Berges, K. Rajagopal
- Physics
- 6 October 1999
Abstract We discuss the Meissner effect for a color superconductor formed by cold dense quark matter. Though color and ordinary electromagnetism are broken in a color superconductor, there is a… Expand
COLOR-SUPERCONDUCTING QUARK MATTER
- M. Alford
- Physics
- 5 February 2001
▪ Abstract I review recent progress in our understanding of the color-superconducting phase of matter above nuclear density, giving particular emphasis to the effort to find observable signatures of… Expand
Astrophysics: Quark matter in compact stars?

- Nature
- 21 June 2006
Arising from: F. Özel. 441, 1115–1117 (2006)10.1038/nature04858; Özel repliesIn a theoretical interpretation of observational data from the neutron star EXO 0748–676, Özel concludes that quark matter… Expand
Astrophysical implications of gapless color-flavor locked quark matter: A hot water bottle for aging
- M. Alford, Pooja Jotwani, C. Kouvaris, Joydip Kundu, K. Rajagopal
- Physics
- 27 June 2005
The gapless color-flavor locked (gCFL) phase is a candidate for the second-densest phase of matter in the QCD phase diagram, making it a plausible constituent of the core of neutron stars. We show… Expand
Imaginary chemical potential and finite fermion density on the lattice
- M. Alford, A. Kapustin, F. Wilczek
- Physics
- 29 July 1998
Standard lattice fermion algorithms run into the well-known sign problem at real chemical potential. In this paper we investigate the possibility of using imaginary chemical potential, and argue that… Expand
Insight into the scalar mesons from a lattice calculation
Abstract We study the possibility that the light scalar mesons are q 2 q 2 states rather than q q . We perform a lattice QCD calculation of pseudoscalar meson scattering amplitudes, ignoring quark… Expand
Unlocking Color and Flavor in Superconducting Strange Quark Matter
- M. Alford, J. Berges, K. Rajagopal
- Physics
- 26 March 1999
Abstract We explore the phase diagram of strongly interacting matter with massless u and d quarks as a function of the strange quark mass m s and the chemical potential μ for baryon number.… Expand
