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…
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…
High-energy magnetic excitations in BiSrCaCuO: Towards a unified description of the electronic and magnetic degrees of freedom in the cuprates
M. P. M. Dean, A. J. A. James, R. S. Springell +10
We investigate the high-energy magnetic excitation spectrum of the high- cuprate superconductor BiSrCaCuO (Bi-2212) using Cu edge resonant inelastic…
On thermal fluctuations in quantum magnets
D. A. Tennant, S. Notbohm, B. Lake +7
The effect of thermal fluctuations on the dynamics of a gapped quantum magnet is studied using inelastic neutron scattering on copper nitrate, a model material for the one-dimensio…
Finite Temperature Dynamical Structure Factor of the Heisenberg-Ising Chain
A. J. A. James, W. D. Goetze, F. H. L. Essler
We consider the spin-1/2 Heisenberg XXZ chain in the regime of large Ising-like anisotropy . By a combination of duality and Jordan-Wigner transformations we derive a mapping to…
Finite Temperature Dynamical Structure Factor of Alternating Heisenberg Chains
A. J. A. James, F. H. L. Essler, R. M. Konik
We develop a low-temperature expansion for the finite temperature dynamical structure factor of the spin half Heisenberg chain with alternating nearest neighbour exchange in the li…
