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 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 establ…
Tensor-network methodology for real-space super-moiré excitons
Anouar Moustaj, Yitao Sun, Tiago V. C. Antão +3
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…
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 spac…
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…
