Quasiparticles are physically motivated mathematical constructs for simplifying the seemingly complicated many-body description of solids. A complete understanding of their dynamics and the nature of the effective interactions between them provides rich information on real material properties at the microscopic level. In this work, we explore the dynamics and interactions of magnon quasiparticles in a ferromagnetic spin-1 Heisenberg chain with easy-axis onsite anisotropy, a model relevant for… 



Tunable Magnon Interactions in a Ferromagnetic Spin-1 Chain.

It is shown how magnetic field strength and direction may be used to directly tune the sign of the magnon-magnon interaction, which has no analog in the more widely studied spin-1/2 systems.

Glide symmetry breaking and Ising criticality in the quasi-1D magnet CoNb2O6

A microscopic Hamiltonian is proposed that reproduces the entirety of the experimental phenomenology of the quasi-1D Ising magnet CoNb2O6 and gives a unified microscopic explanation of the dispersion of confined states in the ordered phase and quasiparticle breakdown in the polarized phase at high transverse field.

Spin transport in a tunable Heisenberg model realized with ultracold atoms.

In this model, the Heisenberg model describing spins on a lattice, with fully adjustable anisotropy of the nearest-neighbour spin-spin couplings is realized, and spin transport far from equilibrium after quantum quenches from imprinted spin-helix patterns is studied.

Fractional spinon excitations in the quantum Heisenberg antiferromagnetic chain

One of the simplest quantum many-body systems is the spin-1/2 Heisenberg antiferromagnetic chain, a linear array of interacting magnetic moments. Its exact ground state is a macroscopic singlet

Disorder-free localization and many-body quantum scars from magnetic frustration

Geometrical frustration has led to rich insights into condensed matter physics, especially as a mechansim to produce exotic low energy states of matter. Here we show that frustration provides a

Duality and domain wall dynamics in a twisted Kitaev chain

The Ising chain in transverse field is a paradigmatic model for a host of physical phenomena, including spontaneous symmetry breaking, topological defects, quantum criticality, and duality. Although

Exact three-colored quantum scars from geometric frustration

Non-equilibrium properties of quantum materials present many intriguing properties, among them athermal behavior, which violates the eigenstate thermalization hypothesis. Such behavior has primarily

Unusual phases in quantum spin-1 systems

Amplitude mode in the planar triangular antiferromagnet Na0.9MnO2

The results show that geometric frustration of Heisenberg spins with uniaxial single-ion anisotropy can renormalize the interactions of a dense two-dimensional network of moments into largely decoupled, one-dimensional chains that manifest a longitudinally polarized-bound state.

Macroscopically Degenerate Exactly Solvable Point in the Spin-1/2 Kagome Quantum Antiferromagnet.

This work reports the discovery of a special quantum macroscopically degenerate point in the XXZ model on the spin-1/2 kagome quantum antiferromagnet for the ratio of Ising toantiferromagnetic transverse coupling J_{z}/J=-1/3 and identifies five phases near this point including both spin-liquid and broken-symmetry phases.
