Low Energy Excitations of a 1D Fermi Gas with Attractive Interactions
Aashish Kafle, Ruwan Senaratne, Danyel Cavazos-Cavazos +5
The low-energy excitations of a two-component repulsive Fermi gas confined to one dimension are linear dispersing spin- and charge-density waves whose respective propagation veloci…

Magnetic and phononic dynamics in the two-ladder quantum magnet (C5H9NH3)2CuBr4
J. Philippe, F. Elson, T. Arh +20
In quantum magnetic materials it is common to observe both static and dynamic lattice effects on the magnetic excitation spectrum. Less common is to find that the magnetic correlat…

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.…
