Abstract The next generation of high-capacity, multi-task optical informatics requires sophisticated manipulation multiple degrees freedom (DoFs) light, especially when they are coupled in a non-separable way. Vector beam, as typical state between the spin and orbital angular momentum DoFs, mathematically akin to entangled qubits, has inspired multifarious theories applications both quantum classical regimes. Although qubit rotation is vital ubiquitous operation informatics, its analogue...
We use a generalized spin wave approach and large scale quantum Monte Carlo (QMC) simulations to study the phase diagram quasiparticle excitations of S=1 Heisenberg model with an easy-plane single-ion anisotropy in dimensions d=2 3. consider two alternative approximations for describing paramagnetic state: standard Holstein-Primakoff approximation modified treatment which local constraint (finite dimension Hilbert space) is enforced by introducing Lagrange multiplier. While both produce...
By exploiting the emerging non-Hermitian photonics design at an exceptional point, we demonstrate a microring laser producing single-mode OAM vortex lasing with ability to precisely define topological charge of mode.
Braiding and fusion rules of topological excitations are indispensable invariants in quantum computation orders. While two dimensions (2D) always particlelike anyons, those three (3D) incorporate not only particles but also loops, spatially nonlocal objects, making it novel challenging to study higher dimensions. 2D have been well understood from bulk Chern-Simons field theory edge conformal theory, is yet be thoroughly explored for 3D higher-dimensional theory. Here, we perform a...
A bstract Topological orders are a prominent paradigm for describing quantum many-body systems without symmetry-breaking orders. We present topological field theoretical (TQFT) study on in five-dimensional spacetime (5D) which excitations include not only point-like particles , but also two types of spatially extended objects: closed string-like loops and two-dimensional membranes . Especially, have been rarely explored the literature By introducing higher-form gauge fields, we construct...

Braiding phases among topological excitations are key data for physically characterizing orders. In this paper, we provide a field-theoretical approach towards complete list of mutually compatible braiding orders in (3+1)D spacetime. More concretely, considering discrete gauge group as input data, paper bosonic \particles carrying charges and loops fluxes. Among these excitations, there three classes root processes: particle-loop braidings (i.e., the familiar Aharonov-Bohm phase winding an...
Universal topological data of topologically ordered phases can be captured by quantum field theory in continuous space time taking the limit low energies and long wavelengths. While previous continuum field-theoretical studies orders three-dimensional (3D) real focused on either self-statistics, braiding statistics, shrinking rules, fusion or dimensions, it has yet to systematically put all together a unified framework. Here, we construct $BF$ with twisted terms (e.g., $AAdA$ $AAB$) as well...

We use a generalized Schwinger boson approach to investigate the nature of intermediate phase (separating antiferromagnetic and dimer phases) in Shastry-Sutherland model with exchange anisotropy. Our results confirm plaquette demonstrate that anisotropy (both Ising-like $XY$-like) weakens order ultimately suppresses it altogether for sufficiently strong Interestingly, we find low-energy excitation spectrum state changes dramatically near boundary phase---the location minimum (gapped) lowest...
Universal topological data of topologically ordered phases can be captured by quantum field theory in continuous space time taking the limit low energies and long wavelengths. While previous continuum field-theoretical studies orders $3$D real focus on either self-statistics, braiding statistics, shrinking rules, fusion rules or dimensions, it is yet to systematically put all together a unified framework.

A bstract As a series of work about 5D (spacetime) topological orders, here we employ the path-integral formalism quantum field theory (TQFT) established in Zhang and Ye, JHEP 04 (2022) 138 to explore non-Abelian fusion rules, hierarchical shrinking rules dimensions particle-like, loop-like membrane-like excitations orders. To illustrate, focus on prototypical example twisted BF theories that comprise terms BBA type. First, classify by establishing equivalence classes among all...
In 3D spacetime, topologically ordered phases of matter feature emergent particles called anyons, whose properties like fusion rules and braiding statistics are schematically represented by diagrams. Important consistency conditions, such as pentagon hexagon relations, encoded in 4D higher spacetimes, topological orders support not only point-like but also spatially extended excitations, loops membranes, allowing for diverse data about braiding, fusion, shrinking processes. Recently, these...
