The central quantities, the longitudinal ( T 1 ) and transverse ( T 2 ) relaxation times were postulated to be equal, mirroring standard metals, but T 1 has never been measured for graphite. Here, based on a detailed band structure calculation including spin-orbit coupling, we predict an unexpected behavior of the relaxation times. We find, based on saturation ESR measurements, that T 1 is markedly different from T 2 . Spins injected with perpendicular polarization with respect to the graphene plane have an extraordinarily long lifetime of 100 ns at room temperature. This is ten times more than in the best graphene samples. The spin diffusion length across graphite planes is thus expected to be ultralong, on the scale of ~ 70 μ m, suggesting that thin films of graphite — or multilayer AB graphene stacks — can be excellent platforms for spintronics applications compatible with 2D van der Waals technologies. Finally, we provide a qualitative account of the observed spin relaxation based on the anisotropic spin admixture of the Bloch states in graphite obtained from density functional theory calculations.}, year = {2023}, eissn = {2041-1723}, orcid-numbers = {Márkus, Bence Gábor/0000-0003-1472-0482; Náfrádi, B./0000-0001-9543-2970; Fabian, J./0000-0002-3009-4525} } @article{MTMT:33715377, title = {Lindbladian route towards thermalization of a Luttinger liquid}, url = {https://m2.mtmt.hu/api/publication/33715377}, author = {Bácsi, Ádám and Dóra, Balázs}, doi = {10.1103/PhysRevB.107.125149}, journal-iso = {PHYS REV B}, journal = {PHYSICAL REVIEW B}, volume = {107}, unique-id = {33715377}, issn = {2469-9950}, year = {2023}, eissn = {2469-9969} } @article{MTMT:33693560, title = {Kibble–Zurek scaling due to environment temperature quench in the transverse field Ising model}, url = {https://m2.mtmt.hu/api/publication/33693560}, author = {Bácsi, Ádám and Dóra, Balázs}, doi = {10.1038/s41598-023-30840-4}, journal-iso = {SCI REP}, journal = {SCIENTIFIC REPORTS}, volume = {13}, unique-id = {33693560}, issn = {2045-2322}, abstract = {The Kibble–Zurek mechanism describes defect production due to non-adiabatic passage through a critical point. Here we study its variant from ramping the environment temperature to a critical point. We find that the defect density scales as \tau ^{-d\nu } τ - d ν or \tau ^{-d/z} τ - d / z for thermal or quantum critical points, respectively, in terms of the usual critical exponents and 1/\tau 1 / τ the speed of the drive. Both scalings describe reduced defect density compared to conventional Kibble–Zurek mechanism, which stems from the enhanced relaxation due to bath-system interaction. Ramping to the quantum critical point is investigated by studying the Lindblad equation for the transverse field Ising chain in the presence of thermalizing bath, with couplings to environment obeying detailed balance, confirming the predicted scaling. The von-Neumann or the system-bath entanglement entropy follows the same scaling. Our results are generalized to a large class of dissipative systems with power-law energy dependent bath spectral densities as well.}, year = {2023}, eissn = {2045-2322} } @article{MTMT:33684677, title = {PT -symmetry phase transition in a Bose-Hubbard model with localized gain and loss}, url = {https://m2.mtmt.hu/api/publication/33684677}, author = {Moca, Pascu Catalin and Sticlet, Doru and Dóra, Balázs and Zaránd, Gergely Attila}, doi = {10.1103/PhysRevB.107.115111}, journal-iso = {PHYS REV B}, journal = {PHYSICAL REVIEW B}, volume = {107}, unique-id = {33684677}, issn = {2469-9950}, year = {2023}, eissn = {2469-9969}, orcid-numbers = {Sticlet, Doru/0000-0003-0646-1978} }
