Robust Genuine Multipartite Entanglement in Two Walker Quantum Walks
Sandipan Hazra, Tamoghna Das, Sougato Bose +1
Discrete-time quantum walks provide a versatile framework for investigating the generation, redistribution, and transport of quantum correlations in composite quantum systems. Here…
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…
Lattice thermal transport from phonon spectra beyond perturbation theory
Zezhu Zeng, Michele Simoncelli, David E. Manolopoulos
We develop a molecular dynamics framework to compute the mode-resolved phonon spectral density from classical correlations of an annihilation-like phonon variable. For harmonic osc…
Coupled electron-phonon hydrodynamics and viscous thermoelectric equations
Jennifer Coulter, Bogdan Rajkov, Michele Simoncelli
Non-diffusive, fluid-like transport of charge and heat has been observed in several materials, raising the question of whether they can emerge simultaneously and how they are relat…
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…
Viscous heat backflow and temperature resonances in extreme thermal conductors
Jan DragaÅ¡eviÄ, Bogdan Rajkov, Michele Simoncelli
We demonstrate that non-diffusive, fluid-like heat transport, such as heat backflowing from cooler to warmer regions, can be induced, controlled, and amplified in extreme thermal c…
