Laser-Induced Transient Magnons in Sr3Ir2O7 Throughout the Brillouin Zone
D. G. Mazzone, D. Meyers, Y. Cao +32
Although ultrafast manipulation of magnetism holds great promise for new physical phenomena and applications, targeting specific states is held back by our limited understanding of…
Ladder-like optical conductivity in the spin-fermion model
Laura Classen, Neil J. Robinson, Alexei M. Tsvelik
In the nested limit of the spin-fermion model for the cuprates, one-dimensional physics in the form of half-filled two-leg ladders emerges. We show that the renormalization group f…
Non-Topological Majorana Zero Modes in Inhomogeneous Spin Ladders
Neil J. Robinson, Alexander Altland, Reinhold Egger +6
We show that the coupling of homogeneous Heisenberg spin-1/2 ladders in different phases leads to the formation of interfacial zero energy Majorana bound states. Unlike Majorana bo…
Magnetism in artificial Ruddlesden-Popper iridates leveraged by structural distortions
D. Meyers, Yue Cao, G. Fabbris +18
We report on the tuning of magnetic interactions in superlattices composed of single and bilayer SrIrO inter-spaced with SrTiO. Magnetic scattering shows predominately -…
Non-perturbative methodologies for low-dimensional strongly-correlated systems: From non-abelian bosonization to truncated spectrum methods
Andrew J. A. James, Robert M. Konik, Philippe Lecheminant +2
We review two important non-perturbative approaches for extracting the physics of low-dimensional strongly correlated quantum systems. Firstly, we start by providing a comprehensiv…
"Quasi-particle breakdown" in the quasi-one-dimensional Ising ferromagnet CoNbO
Neil J. Robinson, Fabian H. L. Essler, Ivelisse Cabrera +1
We present experimental and theoretical evidence that an interesting quantum many-body effect -- quasi-particle breakdown -- occurs in the quasi-one-dimensional spin-1/2 Ising-like…
Finite wave vector pairing in doped two-leg ladders
N. J. Robinson, F. H. L. Essler, E. Jeckelmann +1
We consider the effects of Umklapp processes in doped two-leg fermionic ladders. These may emerge either at special band fillings or as a result of the presence of external periodi…
