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…
Zeeman Ladders in Frustrated XYZ Spin Chains
Catalin-Mihai Halati, Viola Romerio, Paul Steffens +3
We investigate the nature of the excitations captured by the dynamical response of XYZ triangular spin-1/2 ladders. We complement experimental inelastic neutron scattering results…
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.…
Dirac Impurity in a Luttinger liquid
Lorenzo Gotta, Thierry Giamarchi
We consider a linearly-dispersing quantum impurity interacting through a contact density-density term with a one-dimensional (1D) superfluid described by the Tomonaga-Luttinger liq…
Hall response of locally correlated two-dimensional electrons at low density
Giacomo Morpurgo, Louk Rademaker, Christophe Berthod +1
We study the Hall constant in a homogeneous two-dimensional fluid of correlated electrons immersed in a perpendicular magnetic field, with special focus on the regime of low carrie…
Low dimensional correlations under thermal fluctuations
N. Kestin, T. Giamarchi
We study the correlation functions of quantum spin ladders at finite temperature, under a magnetic field, in the gapless phase at various relevant temperatures , mom…
