Author(s): Yaroslav Zhumagulov, Denis Kochan, and Jaroslav FabianThe impact of proximity-induced spin-orbit and exchange coupling on the correlated phase diagram of rhombohedral trilayer graphene (RTG) is investigated theoretically. By employing ab initio-fitted effective models of RTG encapsulated by transition metal dichalcogenides (spin-orbit proximity...

Author(s): K. S. Takeda, K. Uchida, K. Nagai, S. Kusaba, S. Takahashi, and K. TanakaElectron-electron scattering on the order of a few to tens of femtoseconds plays a crucial role in the ultrafast electron dynamics of conventional metals. When mid-infrared light is used for driving and the period of light field is comparable to the scattering time in...

Author(s): Ivan Amelio and Nathan GoldmanWe show that lasing in flat-band lattices can be stabilized by means of the geometrical properties of the Bloch states, in settings where the single-particle dispersion is flat in both its real and imaginary parts. We illustrate a general projection method and compute the collective excitations, whi… [Phys. Rev....

Author(s): Wolfgang S. M. Werner, Florian Simperl, Felix Blödorn, Julian Brunner, Johannes Kero, Alessandra Bellissimo, and Olga RidzelTo describe the electron beam attenuation lengths in solids, in addition to a single-exponential law, momentum relaxation must also be taken into account.

Author(s): Tessa Cookmeyer and Sankar Das SarmaThe Kitaev model on a honeycomb lattice may provide a robust topological quantum memory platform, but finding a material that realizes the unique spin-liquid phase remains a considerable challenge. We demonstrate that an effective Kitaev Hamiltonian can arise from a half-filled Fermi-Hubbard Hamilto… [Phys....

Author(s): Soham Chattopadhyay and Dallas R. TrinkleTo better understand diffusion in complex materials, a computational method separating out uncorrelated individual contributions makes it possible to construct new analytic forms for diffusivity.
