Generating quantum error correcting codes from topological pre-thermal scars
William N. Faugno, Frank Barrows, Terry A. Loring +2
Quantum many-body scars are rare nonthermal states embedded within otherwise thermalizing spectra, making them promising candidates for storing and manipulating quantum information…
Non-equilibirum physics of density-difference dependent Hamiltonian: Quantum Scarring from Emergent Chiral Symmetry
William N Faugno, Hosho Katsura, Tomoki Ozawa
Quantum many-body scars represent a form of weak ergodicity breaking that highlights the unusual physics of thermalization in quantum systems. Understanding scar formation promises…
Characterizing the Many Body Localization Crossover as a Metal-Insulator Transition: Localization length from Polarization and Quantum Metric
W. N. Faugno, Tomoki Ozawa
Many body localization (MBL) represents a unique physical phenomenon, providing a testing ground for exploring thermalization, or more precisely its failure. Here we characterize t…
Density dependent gauge field inducing emergent SSH physics, solitons and condensates in a discrete nonlinear Schrödinger equation
William N. Faugno, Mario Salerno, Tomoki Ozawa
We investigate a discrete non-linear Schrödinger equation with dynamical, density-difference-dependent, gauge fields. We find a ground-state transition from a plane wave condensate…
Interaction-induced non-Hermitian topological phases from a dynamical gauge field
William N Faugno, Tomoki Ozawa
We present a minimal non-Hermitian model where a topologically nontrivial complex energy spectrum is induced by inter-particle interactions. Our model consists of a one-dimensional…
Revisiting excitation gaps in the fractional quantum Hall effect
Tongzhou Zhao, Koji Kudo, W. N. Faugno +2
Recent systematic measurements of the quantum well width dependence of the excitation gaps of fractional quantum Hall states in high mobility samples [Villegas Rosales {\it et al.}…
Unconventional parton states at : The role of finite width
William N. Faugno, Tongzhou Zhao, Ajit C. Balram +2
A recent work [Balram, Jain, and Barkeshli, Phys. Rev. Res. , 013349 (2020)] has suggested that an unconventional state describing superconductivity of co…
Origin of the fractional quantum Hall effect in wide quantum wells
Tongzhou Zhao, William N. Faugno, Songyang Pu +2
The nature of the fractional quantum Hall effect at observed in wide quantum wells almost three decades ago is still under debate. Previous studies have investigated it by…
A non-Abelian fractional quantum Hall state at filled Landau level
W. N. Faugno, J. K. Jain, Ajit C. Balram
We consider a non-Abelian candidate state at filling factor state belonging to the parton family. We find that, in the second Landau level of GaAs (i.e. at filling factor $…
Theoretical phase diagram of two-component composite fermions in double layer graphene
William N. Faugno, Ajit C. Balram, Arkadiusz Wójs +1
Theory predicts that double layer systems realize "two-component composite fermions," which are formed when electrons capture both intra- and inter-layer vortices, to produce a wid…
Prediction of a non-Abelian fractional quantum Hall state with -wave pairing of composite fermions in wide quantum wells
William N. Faugno, Ajit C. Balram, Maissam Barkeshli +1
We theoretically investigate the nature of the state at quarter filled lowest Landau level and predict that, as the quantum well width is increased, a transition occurs from the co…
Exotic Bilayer Crystals in a Strong Magnetic Field
William N. Faugno, Alex J. Duthie, David J. Wales +1
Electron bilayers in a strong magnetic field exhibit insulating behavior for a wide range of interlayer separation for total Landau level fillings , which has been i…
