Here, the authors explore the phase diagram of a twisted bilayer ... interaction-driven Haldane insulator, fractional quantum anomalous Hall effect and quantum spin Hall insulators.

The researchers used a Molecular Beam Epitaxy (MBE) grown V-doped (Bi,Sb)₂Te₃ optimized for the high-temperature quantum anomalous Hall (QAH) effect, along with a Dual Hall bar with nanoscale ...

Apr. 28, 2025 — Climate change is increasing the risk of wildfires in many regions of the world. This is due partly to specific weather conditions -- known as fire weather -- that facilitate the ...

From Chern–Simons theory to topological quantum field theory, from knot invariants to Calabi–Yau compactification in string theory, from spacetime topology in cosmology to the recent Nobel Prize ...

Main repository for QMCPACK, an open-source production level many-body ab initio Quantum Monte Carlo code for computing the electronic structure of atoms, molecules, and solids with full performance ...
