Gauging Modulated Symmetries: Bond Algebras, Higher-Form Symmetries, and Symmetry-Enriched Topological Order
Gustavo M. Yoshitome, Pedro R. S. Gomes, Guilherme Delfino
We develop a constructive framework for characterizing modulated symmetries and their gauging in -dimensional lattice systems. The modulation profiles are organized as a finite-…
Kitaev spin liquid in superconducting networks
Guilherme Delfino, Mehmet Dede, Dmitry Green +3
We propose a realization of the Kitaev honeycomb Hamiltonian -- an archetypal spin-liquid model -- in a superconducting metamaterial. The architecture consists of Cooper-pair boxes…
Nonplanar qubit with tunable gauge symmetry
Muqing Yu, Han Bi, Hengli Lo +6
Circuit quantum electrodynamics embeds Josephson junction qubits within superconducting cavities, and has emerged as a leading approach to quantum computing and quantum simulation.…
Graph-based emulation of -dimensional curved spaces with superconducting arrays
Mehmet Dede, Guilherme Delfino, André L. G. Mudry +4
We introduce a framework for emulating graphs and, through them, curved spaces of arbitrary dimension, using arrays of superconducting wires. The array consists of two stacked laye…
Cooper-pair splitters as circuit elements for realizing topological superconductors
Guilherme Delfino, Dmitry Green, Saulius Vaitiekėnas +2
Advances in materials and fabrication of superconducting devices allows the exploration of novel quantum effects in synthetic superconducting systems beyond conventional Josephson…
Fractal Subsystem Symmetries, Anomalies, Boundaries, and Effective Field Theory
Heitor Casasola, Guilherme Delfino, Yizhi You +2
This work reports an extensive study of three-dimensional topological ordered phases that, in one of the directions behave like usual topological order concerning mobility of excit…
Gauging modulated symmetries: Kramers-Wannier dualities and non-invertible reflections
Salvatore D. Pace, Guilherme Delfino, Ho Tat Lam +1
Modulated symmetries are internal symmetries that act in a non-uniform, spatially modulated way and are generalizations of, for example, dipole symmetries. In this paper, we system…
Fractal Subsystem Symmetries, 't Hooft Anomalies, and UV/IR Mixing
Heitor Casasola, Guilherme Delfino, Pedro R. S. Gomes +1
In this work, we study unconventional anisotropic topologically ordered phases in that manifest type-II fractonic physics along submanifolds. While they behave as usual topolo…
Anyon condensation web and multipartite entanglement in 2D modulated gauge theories
Guilherme Delfino, Yizhi You
In this work, we introduce an anyon condensation web that interconnects a broad class of 2D fracton gauge theories with multipolar conservation laws at a microscopic level. We find…
Topological order and Fractons from Gauging Exponential Symmetries
Guilherme Delfino, Claudio Chamon, Yizhi You
We broaden the scope of quantum field theory by introducing a general class of discrete gauge theories that realize either topological order or fracton behavior across dimensions.…
Effective Fractonic Behavior in a Two-Dimensional Exactly Solvable Spin Liquid
Guilherme Delfino, Weslei B. Fontana, Pedro R. S. Gomes +1
In this work we propose a clock model which is exactly solvable on the lattice. We find exotic properties for the low-energy physics, such as UV/IR mixing and excita…
