Rare collapse of fermionic quasiparticles upon coupling to local bosons
Piotr Wrzosek, Adam Kłosiński, Krzysztof Wohlfeld +1
We study the stability of the fermionic quasiparticle in a fermion-boson model on a Bethe lattice, with fermions interacting with local bosons via a polaronic-type coupling. We sol…
Topology of chalcogen chains
Adam Kłosiński, Wojciech Brzezicki, Alexander Lau +4
We investigate the topological properties of the helical atomic chains occurring in elemental selenium and tellurium. We postulate a realistic model that includes spin-orbit intera…
Unravelling the Nature of Spin Excitations Disentangled from Charge Contributions in a Doped Cuprate Superconductor
Wenliang Zhang, Cliò Efthimia Agrapidis, Yi Tseng +7
The nature of the spin excitations in superconducting cuprates is a key question toward a unified understanding of the cuprate physics from long-range antiferromagnetism to superco…
The fate of the spin polaron in the 1D antiferromagnets
Piotr Wrzosek, Adam Kosinski, Yao Wang +3
The stability of the spin polaron quasiparticle, well established in studies of a single hole in the 2D antiferromagnets, is investigated in the 1D antiferromagnets using a t-J mod…
