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…
Real-space spectral functions of three-dimensional billion-size topological non-Hermitian matter with tensor networks
Yitao Sun, Jose L. Lado, Guangze Chen
Non-Hermitian systems host unconventional topological phenomena, while real-space spectral calculations in three dimensions remain computationally challenging. Here, we develop a t…
Atomically Reconfigurable Single-Molecule Optoelectronics
Atif Ghafoor, Santeri Neuvonen, Thinh Tran +6
Deterministic control of excitonic properties is key to advancing nanoscale optoelectronic and quantum technologies and to understanding diverse physical, optical, chemical, and bi…
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…
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…
