We use quantum Monte Carlo methods to calculate the zero-temperature phase diagram of
the two-dimensional homogeneous electron gas. We find a transition from a paramagnetic …

We study the Fermi-surface instabilities of the Pomeranchuk type [Sov. Phys. JETP 8, 361
(1959)] in the spin-triplet channel with high orbital partial waves [F la (l> 0)]. The ordered …

We discuss shape (Pomeranchuk) instabilities of the Fermi surface of a two-dimensional
Fermi system using bosonization. We consider in detail the quantum critical behavior of the …

We analyze the behavior of an itinerant two-dimensional Fermi system near a charge
nematic (n= 2) Pomeranchuk instability in terms of the Landau Fermi-liquid (FL) theory. A …

Spin-orbit coupling plays an important role in determining the properties of solids, and is
crucial for spintronics device applications. Conventional spin-orbit coupling arises …

We address at the mean field level the emergence of a Pomeranchuk instability in a uniform
Fermi liquid with central particle-particle interactions. We find that Pomeranchuk instabilities …

We study the development of electron-electron correlations in circular quantum dots as the
density is decreased. We consider a wide range of both electron number, N⩽ 20, and …

We extend the study of the Fermi surface instability of the Pomeranchuk type into systems
with orbital band structures, which are common features in transition metal oxides. Band …

We discuss the finite temperature properties of the fermion correlation function near the fixed-
point theory of the charge nematic quantum critical point (QCP) of a metallic Fermi system …

Quasiparticle interference (QPI) in spectroscopic imaging scanning tunneling microscopy
provides a powerful method to detect orbital band structures and orbital ordering patterns in …
