Emergent Pair Density Wave Order Across a Lifshitz Transition
Luhang Yang, Elbio Dagotto, Adrian E. Feiguin
We numerically investigate the telltale signs of pair-density-wave order (PDW) in the Kondo-Heisenberg chain by focusing on the momentum resolved spectrum in different parameter re…
Phase diagram of the one dimensional model: Ferromagnetism, triplet pairing, charge and pair density waves
Luhang Yang, Adrian E. Feiguin
We present a density matrix renormalization group (DMRG) study of an extended model with hopping to the first and second neighbors -- the one dimensional model. T…
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 the d…
The fate of pairing and spin-charge separation in the presence of long-range antiferromagnetism
Luhang Yang, Ignacio Hamad, Luis O. Manuel +1
We present a numerical study of competing orders in the 1D - model with long-range RKKY-like staggered spin interactions. By circumventing the constraints imposed by Mermin-W…
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…
