A Two-dimensional Model with Chiral Condensates and Cooper Pairs having QCD-like Phase Structure
Alan Chodos, Fred Cooper, Wenjin Mao +2
We generalize our previous model to an O(N) symmetric two-dimensional model which possesses chiral symmetry breaking and superconducting (Cooper pair condensates) phases at large-N…
Variational Ansatz for PT-Symmetric Quantum Mechanics
Carl Bender, Fred Cooper, Peter Meisinger +1
A variational calculation of the energy levels of a class of PT-invariant quantum mechanical models described by the non-Hermitian Hamiltonian H= p^2 - (ix)^N with N positive and x…
Competing Condensates in Two Dimensions
Alan Chodos, Fred Cooper, Hisakazu Minakata
We generalize our previous 2-dimensional model in which a pairing condensate psi-psi was generated at large N. In the present case, we allow for both psi-psi and a chiral condensat…
