20.500.12556/RUL-169273 Quantum anomalous Hall domains in a quenched topological Mott insulator We study an interacting spinless quadratic band touching model that realizes a topological Mott insulating state. We quench the interaction from a value corresponding to the nematic insulator to that of the quantum anomalous Hall (QAH) ordered phase. We perform time-dependent Hartree-Fock simulations and show that after the quench the system realizes an excited Dirac semimetal state, which is, however, unstable and spontaneously evolves to a state with inhomogeneous nematic and QAH order parameters. The modulations form a stripe pattern that grows exponentially with time until the local Chern marker reaches unity. The alternating QAH order defines a domain structure with boundaries that host chiral sublattice currents. condensed matter physics quantum physics quantum Hall effect topological phase transitions Mott insulators fizika kondenzirane snovi kvantna fizika kvantni Hallov efekt topološki fazni prehodi Mottovi izolatorji true false true Angleški jezik Slovenski jezik Članek v reviji 2025-05-21 16:15:52 2025-05-21 16:15:54 2025-05-22 04:03:49 0000-00-00 00:00:00 2025 0 0 Str. 195141-1-195141-11 iss. 19 Vol. 111 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 538.9 2469-9950 10.1103/PhysRevB.111.195141 236717827 PhysRevB.111.195141.pdf PhysRevB.111.195141.pdf 1 D945D9895B446FB71A3D16A7EE0EA03A cf9750787fcec1c645744b46dacdec908cfec590764d2c1101e5b66e12a24b30 0a990011-364d-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=210544 https://journals.aps.org/prb/abstract/10.1103/PhysRevB.111.195141 0 119c4f53-364d-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=210545 Fakulteta za matematiko in fiziko 0 0 0
