Query: Sliding Luttinger liquid with alternating interwire couplings   We study a phase diagram for the sliding Luttinger liquid (SLL) of coupled
one-dimensional quantum wires packed in a two-dimensional array in the absence
of a magnetic field. We analyze whether nearest-neighbor inter-wire
interactions, stabilize the SLL phase. We construct an analogue of a
Su-Schriefer-Heeger (SSH) model (allowing alternating couplings between wires).
Calculating the scaling dimensions of the two most relevant perturbations,
charge-density wave, and superconducting inter-wire couplings, but excluding
the inter-wire single-particle hybridization, we find a finite stability region
for the SLL. It emerges due to the inter-wire forward scattering interaction,
and remains stable up to a significant asymmetry between alternating couplings.
