Zero-field spin resonance in graphene with proximity-induced spin-orbit coupling
Abhishek Kumar, Saurabh Maiti, Dmitrii L. Maslov
We investigate collective spin excitations in graphene with proximity-induced spin-orbit coupling (SOC) of the Rashba and valley-Zeeman types, as it is the case, e.g., for graphene…
Optical conductivity of a Dirac-Fermi liquid
Prachi Sharma, Alessandro Principi, Dmitrii L. Maslov
A Dirac-Fermi liquid (DFL)--a doped system with Dirac spectrum--is an important example of a non-Galilean-invariant Fermi liquid (FL). Real-life realizations of a DFL include, e.g.…
Quasiparticle and Nonquasiparticle Transport in Doped Quantum Paraelectrics
Abhishek Kumar, Vladimir I. Yudson, Dmitrii L. Maslov
Charge transport in doped quantum paralectrics (QPs) presents a number of puzzles, including a pronounced regime in the resistivity. We analyze charge transport in a QP withi…

We show that a two-dimensional (2D) isotropic Fermi liquid harbors two new types of collective modes, driven by quantum fluctuations, in addition to conventional zero sound: "hidde…

In a number of physical situations, from polarons to Dirac liquids and to non-Fermi liquids, one encounters the "beyond quasiparticles" regime, in which the inelastic scattering ra…

Alexandre Jaoui, Benoît Fauqué, Carl Willem Rischau +8
The Wiedemann-Franz (WF) law establishes a link between heat and charge transport due to electrons in solids. The extent of its validity in presence of inelastic scattering is a qu…

This paper is a short review on the foundations and recent advances in the microscopic Fermi-liquid (FL) theory. We demonstrate that this theory is built on five identities, which…
Optical conductivity of a two-dimensional metal near a quantum-critical point: the status of the "extended Drude formula"
Andrey V. Chubukov, Dmitrii L. Maslov
The optical conductivity of a metal near a quantum critical point (QCP) is expected to depend on frequency not only via the scattering time but also via the effective mass, which a…
