Signatures of nontrivial pairing in the quantum walk of two-component bosons

MK Giri, S Mondal, BP Das, T Mishra - Physical Review Letters, 2022 - APS
Nearest neighbor bosons possessing only on-site interactions do not form on-site bound
pairs in their quantum walk due to fermionization. We obtain signatures of nontrivial on-site …

From deconfined spinons to coherent magnons in an antiferromagnetic Heisenberg chain with long range interactions

L Yang, A Feiguin - SciPost Physics, 2021 - scipost.org
We study the nature of the excitations of an antiferromagnetic (AFM) Heisenberg chain with
staggered long range interactions using the time-dependent density matrix renormalization …

Two component quantum walk in one-dimensional lattice with hop** imbalance

MK Giri, S Mondal, BP Das, T Mishra - Scientific Reports, 2021 - nature.com
We investigate the two-component quantum walk in one-dimensional lattice. We show that
the inter-component interaction strength together with the hop** imbalance between the …

Correlations in few two-component quantum walkers on a tilted lattice

S Sarkar, T Sowiński - Physical Review A, 2020 - APS
We study the effect of intercomponent interactions on the dynamical properties of quantum
walkers. We consider the simplest situation of two indistinguishable noninteracting walkers …

Decades after the discovery of high-temperature superconductivity, understanding the
effects of do** a Mott insulator remains a topic of great relevance, since the fundamental …
