Van Hove tuning of AV3Sb5 kagome metals under pressure and strain
Armando Consiglio, Tilman Schwemmer, Xianxin Wu +5
From first-principles calculations, we investigate the structural and electronic properties of the kagome metals AV3Sb5 (A = Cs, K, Rb) under isotropic and anisotropic pressure. Ch…
Pinwheel valence-bond-crystal ground state of the spin- Heisenberg antiferromagnet on the lattice
Nikita Astrakhantsev, Francesco Ferrari, Nils Niggemann +9
We investigate the nature of the ground-state of the spin- Heisenberg antiferromagnet on the lattice by complementary state-of-the-art numerical techniques,…
Neural Network Evolution Strategy for Solving Quantum Sign Structures
Ao Chen, Kenny Choo, Nikita Astrakhantsev +1
Feed-forward neural networks are a novel class of variational wave functions for correlated many-body quantum systems. Here, we propose a specific neural network ansatz suitable fo…
Delicate topology protected by rotation symmetry: Crystalline Hopf insulators and beyond
Aleksandra Nelson, Titus Neupert, A. Alexandradinata +1
Pontrjagin's seminal topological classification of two-band Hamiltonians in three momentum dimensions is hereby enriched with the inclusion of a crystallographic rotational symmetr…
Topologically localized insulators
Bastien Lapierre, Titus Neupert, Luka Trifunovic
We show that fully-localized, three-dimensional, time-reversal-symmetry-broken insulators do not belong to a single phase of matter but can realize topologically distinct phases th…
Room-temperature quantum spin Hall edge state in a higher-order topological insulator BiBr
Nana Shumiya, Md Shafayat Hossain, Jia-Xin Yin +24
Room-temperature realization of macroscopic quantum phenomena is one of the major pursuits in fundamental physics. The quantum spin Hall state, a topological quantum phenomenon tha…
