At strong interaction, there is a molecular bound state separated by a direct gap from a continuous band of atomic states. Introducing weak disorder in the interaction, the molecular state becomes Anderson-localized. At stronger disorder, part of the molecular band delocalizes and dissociates due to its hybridization to the atomic band. We characterize these different regimes by computing the density of states, the inverse participation ratio, the level-spacing statistics, and the survival probability of an initially localized state. The atomic band is best described as that of a rough billiard for a single particle on a square lattice that shows signatures of quantum chaos. In addition to typical "chaotic states," we find states that are localized along only one direction. These "separatrix states" are more localized than chaotic states, and similar in this respect to scarred states, but their existence is due to the separatrix isoenergy line in the interaction-free dispersion relation, rather than to unstable periodic orbits.}, keywords = {MODEL; DIFFUSION; TRANSITION; absence; FERROMAGNETISM; MOTT INSULATOR; scars; COHERENT PROPAGATION}, year = {2021}, eissn = {2469-9969} } @article{MTMT:31794714, title = {Topological delocalization in the completely disordered two-dimensional quantum walk}, url = {https://m2.mtmt.hu/api/publication/31794714}, author = {Asbóth, János Károly and Mallick, A.}, doi = {10.1103/PhysRevB.102.224202}, journal-iso = {PHYS REV B}, journal = {PHYSICAL REVIEW B}, volume = {102}, unique-id = {31794714}, issn = {2469-9950}, year = {2020}, eissn = {2469-9969} } @article{MTMT:31817419, title = {Anomalous levitation and annihilation in Floquet topological insulators}, url = {https://m2.mtmt.hu/api/publication/31817419}, author = {Liu, H and Fulga, IC and Asbóth, János Károly}, doi = {10.1103/PhysRevResearch.2.022048}, journal-iso = {PRRESEARCH}, journal = {PHYSICAL REVIEW RESEARCH}, volume = {2}, unique-id = {31817419}, year = {2020}, eissn = {2643-1564} } @article{MTMT:31458767, title = {Topologically Protected Correlated End Spin Formation in Carbon Nanotubes}, url = {https://m2.mtmt.hu/api/publication/31458767}, author = {Moca, Pascu Catalin and Izumida, W and Dóra, Balázs and Legeza, Örs and Asbóth, János Károly and Zaránd, Gergely Attila}, doi = {10.1103/PhysRevLett.125.056401}, journal-iso = {PHYS REV LETT}, journal = {PHYSICAL REVIEW LETTERS}, volume = {125}, unique-id = {31458767}, issn = {0031-9007}, year = {2020}, eissn = {1079-7114} } @article{MTMT:30758121, title = {Poor man's topological quantum gate based on the Su-Schrieffer-Heeger model}, url = {https://m2.mtmt.hu/api/publication/30758121}, author = {Boross, Péter and Asbóth, János Károly and Széchenyi, Gábor and Oroszlány, László and Pályi, András}, doi = {10.1103/PhysRevB.100.045414}, journal-iso = {PHYS REV B}, journal = {PHYSICAL REVIEW B}, volume = {100}, unique-id = {30758121}, issn = {2469-9950}, year = {2019}, eissn = {2469-9969}, orcid-numbers = {Széchenyi, Gábor/0000-0002-4039-7546; Oroszlány, László/0000-0001-5682-6424} } @article{MTMT:30761527, title = {Ifjú Fizikusok Nemzetközi Versenye 2018 – magyar szemmel – 1. rész}, url = {https://m2.mtmt.hu/api/publication/30761527}, author = {Kovács, Levente and Nagy, Dániel and Szakály, Marcell and Hömöstrei, Mihály and Ispánovity, Péter Dusán and Asbóth, János Károly and Tüzes, Dániel and Jenei, Péter}, journal-iso = {FIZIKAI SZEMLE}, journal = {FIZIKAI SZEMLE}, volume = {69}, unique-id = {30761527}, issn = {0015-3257}, year = {2019}, pages = {201-208}, orcid-numbers = {Ispánovity, Péter Dusán/0000-0002-9956-0061; Tüzes, Dániel/0000-0001-7262-8938; Jenei, Péter/0000-0001-5187-9893} } @article{MTMT:30732583, title = {Creating anomalous Floquet Chern insulators with magnetic quantum walks}, url = {https://m2.mtmt.hu/api/publication/30732583}, author = {Sajid, M and Asbóth, János Károly and Meschede, D and Werner, RF and Alberti, A}, doi = {10.1103/PhysRevB.99.214303}, journal-iso = {PHYS REV B}, journal = {PHYSICAL REVIEW B}, volume = {99}, unique-id = {30732583}, issn = {2469-9950}, year = {2019}, eissn = {2469-9969} } @article{MTMT:31529883, title = {Topological insulators: How the deep controls the superficial}, url = {https://m2.mtmt.hu/api/publication/31529883}, author = {Asbóth, János Károly}, doi = {10.1051/epn/2018401}, journal-iso = {EUROPHYS NEWS}, journal = {EUROPHYSICS NEWS}, volume = {49}, unique-id = {31529883}, issn = {0531-7479}, abstract = {Topological insulators prevent current from passing through, but also ensure that it flows unimpeded from contact to contact on their surface.

The aim is to provide a basic understanding of edge states, bulk topological invariants, and of the bulk--boundary correspondence with as simple mathematical tools as possible. We use noninteracting lattice models of topological insulators, building gradually on these to arrive from the simplest one-dimensional case (the Su-Schrieffer-Heeger model for polyacetylene) to two-dimensional time-reversal invariant topological insulators (the Bernevig-Hughes-Zhang model for HgTe). In each case the model is introduced first and then its properties are discussed and subsequently generalized.
