Employing the theory of generalized hydrodynamics, we demonstrate that this model exhibits separation of the transport of topological charge vs energy. Analysis of the quasiparticle dynamics reveals that the mechanism behind the separation is the reflective scattering between topologically charged kinks/antikinks. The effect of these scattering events is most pronounced at strong coupling and low temperatures, where the distribution of quasiparticles is narrow compared to the reflective scattering amplitude. This effect results in a distinctively shaped “arrowhead” light cone for the topological charge.}, year = {2024}, eissn = {2469-9969}, orcid-numbers = {Møller, Frederik/0000-0002-5095-4393; Takács, Gábor/0000-0002-7075-3580} } @article{MTMT:34777533, title = {Molecular Dynamics Study of Nanoribbon Formation by Encapsulating Cyclic Hydrocarbon Molecules inside Single-Walled Carbon Nanotube}, url = {https://m2.mtmt.hu/api/publication/34777533}, author = {Eskandari, Somayeh and Koltai, János and László, István and Kürti, Jenő}, doi = {10.3390/nano14070627}, journal-iso = {NANOMATERIALS-BASEL}, journal = {NANOMATERIALS}, volume = {14}, unique-id = {34777533}, abstract = {Carbon nanotubes filled with organic molecules can serve as chemical nanoreactors. Recent experimental results show that, by introducing cyclic hydrocarbon molecules inside carbon nanotubes, they can be transformed into nanoribbons or inner tubes, depending on the experimental conditions. In this paper, we present our results obtained as a continuation of our previous molecular dynamics simulation work. In our previous work, the initial geometry consisted of independent carbon atoms. Now, as an initial condition, we have placed different molecules inside a carbon nanotube (18,0): C5H5 (fragment of ferrocene), C5, C5+H2; C6H6 (benzene), C6, C6+H2; C20H12 (perylene); and C24H12 (coronene). The simulations were performed using the REBO-II potential of the LAMMPS software package, supplemented with a Lennard-Jones potential between the nanotube wall atoms and the inner atoms. The simulation proved difficult due to the slow dynamics of the H abstraction. However, with a slight modification of the parameterization, it was possible to model the formation of carbon nanoribbons inside the carbon nanotube.}, year = {2024}, eissn = {2079-4991}, orcid-numbers = {Koltai, János/0000-0003-2576-9740; Kürti, Jenő/0000-0001-9752-2769} } @article{MTMT:34749664, title = {Braiding-based quantum control of a Majorana qubit built from quantum dots}, url = {https://m2.mtmt.hu/api/publication/34749664}, author = {Boross, P. and Pályi, András}, doi = {10.1103/PhysRevB.109.125410}, journal-iso = {PHYS REV B}, journal = {PHYSICAL REVIEW B}, volume = {109}, unique-id = {34749664}, issn = {2469-9950}, year = {2024}, eissn = {2469-9969} } @article{MTMT:34749016, title = {Real-space nonlocal Gilbert damping from exchange torque correlation applied to bulk ferromagnets and their surfaces}, url = {https://m2.mtmt.hu/api/publication/34749016}, author = {Nagyfalusi, Balázs and Szunyogh, László and Palotás, Krisztián}, doi = {10.1103/PhysRevB.109.094417}, journal-iso = {PHYS REV B}, journal = {PHYSICAL REVIEW B}, volume = {109}, unique-id = {34749016}, issn = {2469-9950}, year = {2024}, eissn = {2469-9969}, orcid-numbers = {Palotás, Krisztián/0000-0002-1914-2901} } @article{MTMT:34749006, title = {Chemical potential of magnetic skyrmion quasiparticles in heavy-metal/iron bilayers}, url = {https://m2.mtmt.hu/api/publication/34749006}, author = {Nagyfalusi, Balázs and Udvardi, László and Szunyogh, László and Rózsa, Levente}, doi = {10.1103/PhysRevB.109.094418}, journal-iso = {PHYS REV B}, journal = {PHYSICAL REVIEW B}, volume = {109}, unique-id = {34749006}, issn = {2469-9950}, year = {2024}, eissn = {2469-9969}, orcid-numbers = {Rózsa, Levente/0000-0001-9456-5755} } @article{MTMT:34742349, title = {Az elektromágneses sugárzás távolhatása, avagy mire jó a Poynting-vektor; illetve tudunk-e a fénynél gyorsabban haladó jeleket előállítani?}, url = {https://m2.mtmt.hu/api/publication/34742349}, author = {Fürjes, Bálint and Dóra, Balázs and Simon, Ferenc}, journal-iso = {FIZIKAI SZEMLE}, journal = {FIZIKAI SZEMLE}, volume = {74}, unique-id = {34742349}, issn = {0015-3257}, year = {2024}, pages = {102-106} } @article{MTMT:34675872, title = {Two levels of topology in skyrmion lattice dynamics}, url = {https://m2.mtmt.hu/api/publication/34675872}, author = {Schick, D and Weissenhofer, M and Rózsa, Levente and Rothörl, J and Virnau, P and Nowak, U}, doi = {10.1103/PhysRevResearch.6.013097}, journal-iso = {PRRESEARCH}, journal = {PHYSICAL REVIEW RESEARCH}, volume = {6}, unique-id = {34675872}, year = {2024}, eissn = {2643-1564}, orcid-numbers = {Rózsa, Levente/0000-0001-9456-5755} } @article{MTMT:34629567, title = {Bichromatic Rabi Control of Semiconductor Qubits}, url = {https://m2.mtmt.hu/api/publication/34629567}, author = {John, V. and Borsoi, F. and György, Z. and Wang, C.-A. and Széchenyi, Gábor and Van, Riggelen-Doelman F. and Lawrie, W.I.L. and Hendrickx, N.W. and Sammak, A. and Scappucci, G. and Pályi, András and Veldhorst, M.}, doi = {10.1103/PhysRevLett.132.067001}, journal-iso = {PHYS REV LETT}, journal = {PHYSICAL REVIEW LETTERS}, volume = {132}, unique-id = {34629567}, issn = {0031-9007}, year = {2024}, eissn = {1079-7114}, orcid-numbers = {Széchenyi, Gábor/0000-0002-4039-7546} } @article{MTMT:34569656, title = {Segmented strings and holography}, url = {https://m2.mtmt.hu/api/publication/34569656}, author = {Boldis, Bercel and Lévay, Péter Pál}, doi = {10.1103/PhysRevD.109.046002}, journal-iso = {PHYS REV D}, journal = {PHYSICAL REVIEW D}, volume = {109}, unique-id = {34569656}, issn = {2470-0010}, year = {2024}, eissn = {2470-0029}, orcid-numbers = {Boldis, Bercel/0000-0002-8443-7538; Lévay, Péter Pál/0000-0002-3436-9952} } @article{MTMT:34568147, title = {Complete replica solution for the transverse field Sherrington-Kirkpatrick spin glass model with continuous-time quantum Monte Carlo method}, url = {https://m2.mtmt.hu/api/publication/34568147}, author = {Kiss, Annamária and Zaránd, Gergely Attila and Lovas, I.}, doi = {10.1103/PhysRevB.109.024431}, journal-iso = {PHYS REV B}, journal = {PHYSICAL REVIEW B}, volume = {109}, unique-id = {34568147}, issn = {2469-9950}, abstract = {We construct a complete numerically exact solution of a mean-field quantum spin glass model - the transverse field Sherrington-Kirkpatrick model - by implementing a continuous-time quantum Monte Carlo method in the presence of full replica symmetry breaking. We extract the full numerically exact phase diagram, displaying a glassy phase with continuous replica symmetry breaking at small transverse fields and low temperatures. A paramagnetic phase emerges once thermal and quantum fluctuations melt the spin glass. We characterize both phases by extracting the order parameter as well as the static and dynamical local spin susceptibilities. The static susceptibility shows a plateau in the glassy phase, but it remains smooth across the phase boundary. For the imaginary part of the dynamical susceptibility, we find an Ohmic, i.e., linear in ω, scaling for small frequencies ω, with a slope independent of the transverse field. These results compare qualitatively well with ac susceptibility measurements on a dipole-coupled three-dimensional Ising magnet - the LiHoxY1-xF4 compound - in a transverse magnetic field. Our work provides a general framework for the exact numerical solution of mean-field quantum glass models, and it constitutes an important step towards understanding glassiness in realistic systems. © 2024 American Physical Society.}, keywords = {GLASS; MEAN-FIELD; Monte Carlo methods; Continuous time systems; lithium compounds; Magnetic susceptibility; TRANSVERSE FIELD; Spin glass; Exact solution; SPIN-GLASS MODELS; Glassy phase; Quantum Monte Carlo methods; Sherrington; Time quantum; Continous time; Kirkpatrick}, year = {2024}, eissn = {2469-9969} }
