Tensor network solvers for ultra-large tight-binding Hamiltonians: algorithms and applications
Tiago V. C. Antão, Anouar Moustaj, Yitao Sun +1
Understanding quantum materials at meso and even macroscopic scales requires tight-binding calculations on system sizes where explicit matrix representations become prohibitively c…
Tensor-network methodology for real-space super-moiré excitons
Anouar Moustaj, Yitao Sun, Tiago V. C. Antão +2
Computing excitonic spectra in quasicrystal and super-moiré systems constitutes a formidable challenge due to the exceptional size of the excitonic Hilbert space. Here, we demonstr…
Tensor network approach to momentum-resolved spectroscopy in non-periodic super-moiré systems
Anouar Moustaj, Yitao Sun, Tiago V. C. Antão +1
Computing spectral functions in large, non-periodic super-moiré systems remains an open problem due to the exceptionally large system size that must be considered. Here, we establi…
Observation of electromagnons in a monolayer multiferroic
Mohammad Amini, Tiago V. C. Antão, Liwei Jing +7
Van der Waals multiferroics have emerged as a promising platform to explore novel magnetoelectric phenomena. Recently, it has been shown that monolayer NiI hosts robust type-II…
Observation of tunable chiral spin textures with nonlinear optics
Youqiang Huang, Tiago V. C. Antao, Adolfo O. Fumega +14
Chiral spin textures, such as spin spirals and skyrmions, are key to advancing spintronics by enabling ultrathin, energy-efficient memory, and high-density data storage and process…
Tensor network method for real-space topology in quasicrystal Chern mosaics
Tiago V. C. Antão, Yitao Sun, Adolfo O. Fumega +1
Computing topological invariants in two-dimensional quasicrystals and super-moire matter is a remarkable open challenge, due to the absence of translational symmetry and the coloss…
Self-consistent tensor network method for correlated super-moiré matter beyond one billion sites
Yitao Sun, Marcel Niedermeier, Tiago V. C. Antão +2
Moiré and super-moiré materials provide exceptional platforms to engineer exotic correlated quantum matter. The vast number of sites required to model moiré systems in real space r…
Electric field control of moiré skyrmion phases in twisted multiferroic NiI bilayers
Tiago V. C. Antão, Jose L. Lado, Adolfo O. Fumega
Twisted magnetic van der Waals materials provide a flexible platform to engineer new forms of unconventional magnetism. Here we demonstrate the emergence of electrically tunable to…
Effects of dilution in a 2D topological magnon insulator
Miguel S. Oliveira, T. V. C. Antão, Eduardo V. Castro +1
We study the effect of diluting a two-dimensional ferromagnetic insulator hosting a topological phase in the clean limit. By considering the ferromagnetic Heisenberg model in the h…
Strain Engineering of Photo-induced Topological Phases in 2D Ferromagnets
T. V. C. Antão, N. M. R. Peres
We argue that strain engineering is a powerful tool which may facilitate the experimental realization and control of topological phases in laser-driven 2D ferromagnetic systems. To…
Laser induced enhanced coupling between photons and squeezed magnons in antiferromagnets
J. C. G. Henriques, T. V. C. Antão, N. M. R. Peres
In this paper we consider a honeycomb antiferromagnet subject to an external laser field. Obtaining a time-independent effective Hamiltonian, we find that the external laser renorm…
Two-level Systems Coupled to Graphene plasmons: A Lindblad equation approach
T. V. C. Antão, N. M. R. Peres
In this paper we review the theory of open quantum systems and macroscopic quantum electrodynamics, providing a self-contained account of many aspects of these two theories. The fo…
The polarizability of a confined atomic system: An application of Dalgarno-Lewis method
T. V. C. Antão, N. M. R. Peres
In this paper we give an application of Dalgarno-Lewis method, the latter not usually taught in quantum mechanics courses. This is very unfortunate since this method allows to bypa…
