Extremely Correlated Fermi Liquid theory for $U=\infty$, $d=\infty$ Hubbard model to $\mathcal{O}({\lambda }^3)$

Samantha Shears, Edward Perepelitsky, Michael Arciniaga +1

We present the $\mathcal{O}({\lambda }^3)$ results from the $\lambda$ expansion in the extremely correlated Fermi liquid theory applied to the infinite-dimensional $t$-$J$ model (with $J=0$), and co…
