Symmetry protected quantum many body scars through half-gauging
Weslei B. Fontana, Fabrizio G. Oliviero, Yi-Ping Huang
We study the interplay between symmetry defects insertion and the phenomena of quantum many body scarring. We exploit a class of models obtained from an embedding mechanism that de…
Quantum many-body scarring from Kramers-Wannier duality
Weslei B. Fontana, Fabrizio G. Oliviero, Yi-Ping Huang
Kramers-Wannier duality, a hallmark of the Ising model, has recently gained renewed interest through its reinterpretation as a non-invertible symmetry with a state-level action. Us…
Partons from stabilizer codes
Rafael A. Macedo, Carlo C. Bellinati, Weslei B. Fontana +2
The Gutzwiller projection of fermionic wave functions is a well-established method for generating variational wave functions describing exotic states of matter, such as quantum spi…
The spin-orbital Kitaev model: from kagome spin ice to classical fractons
Weslei B. Fontana, Fabrizio G. Oliviero, Rodrigo G. Pereira +1
We study an exactly solvable spin-orbital model that can be regarded as a classical analogue of the celebrated Kitaev honeycomb model and describes interactions between Rydberg ato…
Majorana Fermi surface state in a network of quantum spin chains
Fabrizio G. Oliviero, Weslei B. Fontana, Rodrigo G. Pereira
We use junctions of critical spin-1 chains as the basic elements to construct a honeycomb network that harbors a gapless chiral spin liquid phase. The low-energy modes are describe…
Boundary Modes in the Chamon Model
Weslei B. Fontana, Rodrigo G. Pereira
We study the fracton phase described by the Chamon model in a manifold with a boundary. The new processes and excitations emerging at the boundary can be understood by means of a d…
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…
Field Theories for type-II fractons
Weslei B. Fontana, Pedro R. S. Gomes, Claudio Chamon
We derive an effective field theory for a type-II fracton starting from the Haah code on the lattice. The effective topological theory is not given exclusively in terms of an actio…
Lattice Clifford fractons and their Chern-Simons-like theory
Weslei B. Fontana, Pedro R. S. Gomes, Claudio Chamon
We use Dirac matrix representations of the Clifford algebra to build fracton models on the lattice and their effective Chern-Simons-like theory. As an example we build lattice frac…
From Quantum Wires to the Chern-Simons Description of the Fractional Quantum Hall Effect
Weslei B. Fontana, Pedro R. S. Gomes, Carlos A. Hernaski
We show the explicit connection between two distinct and complementary approaches to the fractional quantum Hall system (FQHS): the quantum wires formalism and the topological low-…
Extended quasilocal Thermodynamics of Schwarzchild-anti de Sitter black holes
W. B. Fontana, M. C. Baldiotti, R. Fresneda +1
In this work we study a homogeneous and quasilocal Thermodynamics associated to the Schwarzschild-anti de Sitter black hole. The usual thermodynamic description is extended within…
