Observation of an emergent energy scale close to dimensional reduction in a quasi-two-dimensional quantum magnet
Anneke Reinold, Laur Peedu, Kirill Amelin +19
By appropriately perturbing a critical transverse-field Ising chain away from its critical point, the system can develop a finite correlation length with a characteristic purely ma…

Superconductivity in the repulsive Hubbard model on different geometries induced by density-assisted hopping
Franco T. Lisandrini, Edmond Orignac, Roberta Citro +2
We study the effect of density-assisted hopping on different dimerized lattice geometries, such as bilayers and ladder structures. We show analytically that the density-assisted ho…

Fingerprints of supersymmetric spin and charge dynamics observed by inelastic neutron scattering
Björn Wehinger, Franco T. Lisandrini, Noam Kestin +12
Supersymmetry is an algebraic property of a quantum Hamiltonian that, by giving every boson a fermionic superpartner and vice versa, may underpin physics beyond the Standard Model.…
