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.…
Dynamical susceptibility of a Fermi liquid
Vladimir A. Zyuzin, Prachi Sharma, Dmitrii L. Maslov
We study the dynamic response of a Fermi liquid in the spin, charge and nematic channels beyond the random phase approximation for the dynamically screened Coulomb potential. In al…
Gradient terms in quantum-critical theories of itinerant fermions
Dmitrii L. Maslov, Prachi Sharma, Dmitrii Torbunov +1
We investigate the origin and renormalization of the gradient () term in the propagator of soft bosonic fluctuations in theories of itinerant fermions near a quantum critical…
