Competition and coexistence of baryonic condensates in AdS hardwall model

Abstract

Cold dense QCD admits several order parameters for baryon-number breaking, among them diquark and dibaryon condensates. We ask whether they exclude one another or coexist, using a five-dimensional AdS hardwall model with full backreaction in which two charged scalars, dual to operators of charges qi and dimensions Δi, couple to a common U(1)B gauge field. With the diquark-like operator fixed at q1=2, Δ1=3, both operators condense only within a narrow window of Δ2, which widens with q2 and closes when the operators coincide. Outside the window, only a single condensate forms. The structure persists in both confined and deconfined phases. In the μB-T plane, confined matter with both condensates is preferred at low temperature, below a narrow band of deconfined matter with one condensate.

AB  - Cold dense QCD admits several order parameters for baryon-number breaking, among them diquark and dibaryon condensates. We ask whether they exclude one another or coexist, using a five-dimensional AdS hardwall model with full backreaction in which two charged scalars, dual to operators of charges q_i and dimensions Δ_i, couple to a common U(1)_B gauge field. With the diquark-like operator fixed at q_1=2, Δ_1=3, both operators condense only within a narrow window of Δ_2, which widens with q_2 and closes when the operators coincide. Outside the window, only a single condensate forms. The structure persists in both confined and deconfined phases. In the μ_B-T plane, confined matter with both condensates is preferred at low temperature, below a narrow band of deconfined matter with one condensate.
