Abstract: We formulate a construction of type-I fracton models based on gauging planar subsystem symmetries of topologically ordered two dimensional layers that have been stacked in three ambient spatial dimensions. Via our construction, any defect of an Abelian symmetry group in a two dimensional symmetry-enriched topological order can be promoted into a fracton. This allows us to construct fracton models supporting chiral boundaries and fractons of noninteger quantum dimension. We also find a lineon model supporting non-Abelian surface fractons on its boundary.

We numerically verify and analytically prove a winding number invariant that correctly predicts the number of edge states in one-dimensional, nearest-neighbour (between unit cells) Our invariant is invariant under unitary and similarity transforms.

Topological Order in the Spectral Riemann Surfaces of Non-Hermitian Systems [44.99833362998488]
We show topologically ordered states in the complex-valued spectra of non-Hermitian systems. These arise when the distinctive exceptional points in the energy surfaces of such models are annihilated. We illustrate the characteristics of the topologically protected states in a non-Hermitian two-band model.

Penrose dodecahedron, Witting configuration and quantum entanglement [55.2480439325792]
A model with two entangled spin-3/2 particles based on geometry of dodecahedron was suggested by Roger Penrose. The model was later reformulated using so-called Witting configuration with 40 rays in 4D Hilbert space. Two entangled systems with quantum states described by Witting configurations are discussed in presented work.

Topological classification of Higher-order topological phases with nested band inversion surfaces [0.0]
Higher-order topological phases (HOTPs) hold gapped bulk bands and topological boundary states localized in boundaries with codimension higher than one. We provide a unified construction and topological characterization of HOTPs for the full Altland-Zirnbauer symmetry classes, based on a method known as nested band inversion surfaces (BISs)

Higher-Form Subsystem Symmetry Breaking: Subdimensional Criticality and Fracton Phase Transitions [0.0]
Subsystem symmetry has emerged as a powerful organizing principle for unconventional quantum phases of matter. We show that certain transitions out of familiar fracton phases, including the X-cube model, can be understood in terms of the spontaneous breaking of subsystem symmetries.

Radiative topological biphoton states in modulated qubit arrays [105.54048699217668]
We study topological properties of bound pairs of photons in spatially-modulated qubit arrays coupled to a waveguide. For open boundary condition, we find exotic topological bound-pair edge states with radiative losses. By joining two structures with different spatial modulations, we find long-lived interface states which may have applications in storage and quantum information processing.
