Topological to magnetically ordered quantum phase transition in antiferromagnetic spin ladders with long-range interactions
Luhang Yang, Phillip Weinberg, Adrian E. Feiguin
We study a generalized quantum spin ladder with staggered long range interactions that decay as a power-law with exponent . Using large scale quantum Monte Carlo (QMC) and densi…
Beyond perturbation theory: A time-dependent approach to inelastic scattering spectroscopies in- and away from equilibrium
Krissia Zawadzki, Luhang Yang, Adrian E. Feiguin
We propose a non-perturbative numerical approach to calculate the spectrum of a many-body Hamiltonian with time and momentum resolution by exactly recreating a scattering event usi…
From deconfined spinons to coherent magnons in an antiferromagnetic Heisenberg chain with long range interactions
Luhang Yang, Adrian E. Feiguin
We study the spectrum and the nature of the excitations of an antiferromagnetic (AFM) Heisenberg chain with staggered long range interactions, both numerically using the time-depen…
