WebOct 5, 2024 · Pomeranchuk instability of Fermi liquid parameter F_{ℓ}≤-1 in the angular momentum ℓ=2 channel has been argued to be the relevant mechanism, yet there are no definitive theoretical proofs. Here we calculate, using the variational Monte Carlo technique, Fermi liquid parameters F_{ℓ} of the composite fermion Fermi liquid with a finite layer width. WebAnother instability, so called Pomeranchuk instability 15PI ,has been proposed in the 2D t−t Hubbard model by Halboth and Metzner.16 The PI with d-wave order dPI leads to …
