Color superconductivity and charge neutrality in Yukawa theory
Mark G. Alford, Kamal Pangeni, Andreas Windisch
It is generally believed that when Cooper pairing occurs between two different species of fermions, their Fermi surfaces become locked together so that the resultant state remains…
Liquid-Gas Phase Transitions and Symmetry in Quantum Field Theories
Hiromichi Nishimura, Michael C. Ogilvie, Kamal Pangeni
A general field-theoretic framework for the treatment of liquid-gas phase transitions is developed. Starting from a fundamental four-dimensional field theory at nonzero temperature…
Complex spectrum of spin models for finite-density QCD
Hiromichi Nishimura, Michael Ogilvie, Kamal Pangeni
We consider the spectrum of transfer matrix eigenvalues associated with Polyakov loops in lattice QCD at strong coupling. The transfer matrix at finite density is non-Hermitian, an…
Gap-bridging enhancement of modified Urca processes in nuclear matter
Mark G. Alford, Kamal Pangeni
In nuclear matter at neutron-star densities and temperatures, Cooper pairing leads to the formation of a gap in the nucleon excitation spectra resulting in exponentially strong Bol…
Complex spectrum of finite-density lattice QCD with static quarks at strong coupling
Hiromichi Nishimura, Michael C. Ogilvie, Kamal Pangeni
We calculate the spectrum of transfer matrix eigenvalues associated with Polyakov loops in finite-density lattice QCD with static quarks. These eigenvalues determine the spatial be…
Complex saddle points in finite-density QCD
Hiromichi Nishimura, Michael C. Ogilvie, Kamal Pangeni
We consider complex saddle points in QCD at finite temperature and density, which are constrained by symmetry under charge and complex conjugations. This approach naturally incorpo…
Complex Saddle Points and Disorder Lines in QCD at finite temperature and density
Hiromichi Nishimura, Michael C. Ogilvie, Kamal Pangeni
The properties and consequences of complex saddle points are explored in phenomenological models of QCD at non-zero temperature and density. Such saddle points are a consequence of…
Complex saddle points in QCD at finite temperature and density
Hiromichi Nishimura, Michael C. Ogilvie, Kamal Pangeni
The sign problem in QCD at finite temperature and density leads naturally to the consideration of complex saddle points of the action or effective action. The global symmetry $\mat…
