Luttinger Theorem for the Strongly Correlated Fermi Liquid of Composite Fermions.
While an ordinary Fermi sea is perturbatively robust to interactions, the paradigmatic composite-fermion (CF) Fermi sea arises as a nonperturbative consequence of emergent gauge fields in a system where there was no Fermi sea to begin with. A mean-field picture suggests two Fermi seas, of composite fermions made from electrons or holes in the lowest Landau level, which occupy different areas aw...
متن کاملNon-fermi Liquid Ground States in Certain Heavy Fermions
Acknowledgments I would like to thank Mark Jarrell for all the guidance he provided throughout my time here in Cincinnati. Without his help in suggesting problems and strategies, little or none of this work would have been possible. I thank him for providing the opportunity to visit collaborators, for being patient while I dabbled with diierent problems, and for the numerous nice dinners at his...
متن کاملComposite fermions with a warped Fermi contour.
Via measurements of commensurability features near the Landau filling factor ν=1/2, we probe the shape of the Fermi contour for hole-flux composite fermions confined to a wide GaAs quantum well. The data reveal that the composite fermions are strongly influenced by the characteristics of the Landau level in which they are formed. In particular, their Fermi contour is warped when their Landau le...
متن کاملSimulation of strongly correlated fermions in two spatial dimensions with fermionic Projected Entangled-Pair States
We explain how to implement, in the context of projected entangled-pair states (PEPS), the general procedure of fermionization of a tensor network introduced in [P. Corboz, G. Vidal, Phys. Rev. B 80, 165129 (2009)]. The resulting fermionic PEPS, similar to previous proposals, can be used to study the ground state of interacting fermions on a two-dimensional lattice. As in the bosonic case, the ...
