Conserving relaxation-time approximation for electron-electron collisions
Sayak Bhattacharjee, Tatia Kiliptari, Dmitrii L. Maslov
We develop a conserving relaxation-time approximation (cRTA) based on an explicit energy-resolved projection onto the full space of collision invariants. Our cRTA retains the energ…
Energy relaxation due to two-phonon scattering of electrons: Breakdown of the energy diffusion model
Joshua Covey, Dmitrii L. Maslov
Recent THz spectroscopy of the quantum paraelectric SrTiO (arXiv:2501.15771) and a high- cuprate (arXiv:2503.15646) has renewed interest in energy relaxation in correlated…
Magnetoconductivity due to electron-electron interaction in a non-Galilean-invariant Fermi liquid
Tatia Kiliptari, Dmitrii L. Maslov
The -scaling of resistivity with temperature is often viewed as a classic hallmark of a Fermi-liquid (FL) behavior in metals. However, if umklapp scattering is suppressed, thi…
Resistive Anomaly near a Ferromagnetic Phase Transition: A Classical Memory Effect
Dmitrii L. Maslov, Vladimir I. Yudson, Cristian D. Batista
We investigate resistive anomalies in metals near ferromagnetic phase transitions, focusing on the role of long-range critical fluctuations. Our analysis reveals that diffusive mot…
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…
Optical conductivity and damping of plasmons due to electron-electron interaction
Prachi Sharma, Alessandro Principi, Giovanni Vignale +1
We re-visit the issue of plasmon damping due to electron-electron interaction. The plasmon linewidth can related to the imaginary part of the charge susceptibility or, equivalently…
