Collective excitations and stability of a non-Fermi liquid state near a quantum-critical point of a metal
Yasha Gindikin, Dmitrii L. Maslov, Andrey V. Chubukov
We examine the spectral properties of collective excitations with finite angular momentum for a system of interacting fermions near a Pomeranchuk quantum critical point, both i…
Quantum criticality and optical conductivity in a two-valley system
Yasha Gindikin, Songci Li, Alex Levchenko +3
We demonstrate that the optical conductivity of a Fermi liquid (FL) in the absence of umklapp scattering is dramatically affected by the topology of the Fermi surface (FS). Specifi…
Fermi Surface Geometry and Optical Conductivity of a 2D Electron Gas near an Ising-Nematic Quantum Critical Point
Yasha Gindikin, Andrey V. Chubukov
We analyze optical conductivity of a clean two-dimensional electron system in a Fermi liquid regime near a Ising-nematic quantum critical point (QCP), and extrapolate the res…
Electron Interactions in Rashba Materials
Yasha Gindikin, Alex Kamenev
We present a bunch of novel phenomena stemming from the pair spin-orbit interaction (PSOI), which does not rely on structure inversion asymmetry but instead arises from Coulomb fie…
Electron pairs bound by the spin-orbit interaction in 2D gated Rashba materials with two-band spectrum
Yasha Gindikin, Igor Rozhansky, Vladimir A. Sablikov
We show that the bound electron pairs (BEPs) emerge in two-dimensional gated Rashba materials owing to the interplay of the pair spin-orbit interaction, produced by the Coulomb fie…
Spin-dependent electron-electron interaction in Rashba materials
Yasha Gindikin, Vladimir A. Sablikov
We review the effects of the pair spin-orbit interaction (PSOI) in Rashba materials. The PSOI is the electron-electron interaction component that depends on the spin and momentum o…
Electron correlations due to pair spin-orbit interaction in 2D electron systems
Yasha Gindikin, Vladimir A. Sablikov
We show that the pair spin-orbit interaction (PSOI) created by the Coulomb fields of interacting electrons leads to the appearance of an unconventional correlated electronic state…

Yasha Gindikin, Vladimir A. Sablikov
We show that the spin-orbit interaction (SOI) produced by the Coulomb fields of charged impurities provides an efficient mechanism for the bound states formation. The mechanism can…
Pair spin-orbit interaction in low-dimensional electron systems
Yasha Gindikin, Vladimir A. Sablikov
The pair spin-orbit interaction (PSOI) is the spin-orbit component of the electron-electron interaction that originates from the Coulomb fields of the electrons. This relativistic…
Bound electron pairs formed by the spin-orbit interaction in 2D gated structures
Yasha Gindikin, Vitalina Vigdorchik, Vladimir A. Sablikov
We explore the bound electron pairs (BEPs) arising due to the pair spin-orbit interaction (PSOI) in two-dimensional structures with a gate that can allow the BEPs to be manipulated…
Coulomb pairing of electrons in thin films with strong spin-orbit interaction
Yasha Gindikin, Vladimir A. Sablikov
In low-dimensional structures with strong Rashba spin-orbit interaction (SOI), the Coulomb fields between moving electrons produce a SOI component of the pair interaction that comp…
Spin-orbit-driven electron pairing in two dimensions
Yasha Gindikin, Vladimir A. Sablikov
We show that the spin-orbit interaction (SOI) arising due to the in-plane electric field of the Coulomb repulsion between electrons in a two-dimensional quantum well produces an at…
The spin-orbit mechanism of electron pairing in quantum wires
Yasha Gindikin, Vladimir A. Sablikov
We solve a two-body problem for electrons in a one-dimensional system to show that two-electron bound states can arise as a result of the image-potential-induced spin-orbit interac…
Dynamic transport in a quantum wire driven by spin-orbit interaction
Yasha Gindikin
We consider a gated one-dimensional (1D) quantum wire disturbed in a contactless manner by an alternating electric field produced by a tip of a scanning probe microscope. In this s…
Dynamics of one-dimensional electrons with broken spin-charge separation
Yasha Gindikin, Vladimir A. Sablikov
Spin-charge separation is known to be broken in many physically interesting one-dimensional (1D) and quasi-1D systems with spin-orbit interaction because of which spin and charge d…
Image-potential-induced spin-orbit interaction in one-dimensional electron systems
Yasha Gindikin, Vladimir A. Sablikov
We study the spin-orbit interaction effects in a one-dimensional electron system that result from the image charges in a nearby metallic gate. The nontrivial property of the image-…
Probe-assisted spin manipulation in one-dimensional quantum dots

We study a spin structure that arises in a one-dimensional quantum dot with zero total spin under the action of a charged tip of a scanning probe microscope in the presence of a we…
Deformed Wigner crystal in a one-dimensional quantum dot
Yasha Gindikin, Vladimir A. Sablikov
The spatial Fourier spectrum of the electron density distribution in a finite 1D system and the distribution function of electrons over single-particle states are studied in detail…
On the "effective exponent theory" of the Coulomb Luttinger liquid
Yasha Gindikin, V. A. Sablikov
The "effective exponent theory", developed by Wang, Millis and Das Sarma in [Phys. Rev. B 69, 167101 (2004), Phys. Rev. B 64, 193307 (2001)], fails to calculate correctly the dynam…
Reply to 'Comment on "Dynamic correlations of the spinless Coulomb Luttinger liquid [Phys. Rev. B 65, 125109 (2002)]"'
Yasha Gindikin, V. A. Sablikov
We show that the criticism of our paper [Phys. Rev. B 65, 125109 (2002)] by Wang, Millis, and Das Sarma [cond-mat/0206203] is based on a trivial mathematical mistake they have comm…

Vladimir A. Sablikov, Yasha Gindikin
The density operator in the Luttinger model consists of two components, one of which describes long-wave fluctuations and the other is related to the rapid oscillations of the char…
