Thermal transport in crystals: from the quantum Dyson equation to mesoscopic phonon hydrodynamics
Enrico Di Lucente, Michele Simoncelli, Nicola Marzari
Thermal transport in dielectric, non-magnetic crystals is mediated by quantized lattice vibrations, which drift and interact when driven out of equilibrium by a temperature gradien…

Competition between local magnetic disorder and altermagnetism in doped FeSb
Enrico Di Lucente, Michele Simoncelli
Recent experimental reports suggest that the narrow-gap nonmagnetic semiconductor FeSb can be transformed into an altermagnetic metal through Co doping (CoFeS…

Phonon collisional broadening and heat transport beyond the Boltzmann equation
Enrico Di Lucente, Nicola Marzari, Michele Simoncelli
In crystals, macroscopic technological properties such as thermal conductivity originate from the microscopic drift and scattering of phonons, commonly described by the Boltzmann T…
