Quantum many-body scars with chiral topological order in 2D and critical properties in 1D
N. S. Srivatsa, Julia Wildeboer, Alexander Seidel +1
We construct few-body, interacting, nonlocal Hamiltonians with a quantum scar state in an otherwise thermalizing many-body spectrum. In one dimension, the embedded state is a criti…
Exact Solution and Correlations of a Quantum Dimer Model on the Checkerboard Lattice
Julia Wildeboer, Zohar Nussinov, Alexander Seidel
We present analytic results for a special dimer model on the {\em non-bipartite} and {\em non-planar} checkerboard lattice that does not allow for parallel dimers surrounding diago…
Quasiparticles as Detector of Topological Quantum Phase Transitions
Sourav Manna, N. S. Srivatsa, Julia Wildeboer +1
A number of tools have been developed to detect topological phase transitions in strongly correlated quantum systems. They apply under different conditions, but do not cover the fu…
Quasielectrons in lattice Moore-Read models
Sourav Manna, Julia Wildeboer, Anne E. B. Nielsen
Moore-Read states can be expressed as conformal blocks of the underlying rational conformal field theory, which provides a well explored description for the insertion of quasiholes…
First-order Néel-cVBS transition in a model square lattice antiferromagnet
Julia Wildeboer, Nisheeta Desai, Jonathan D'Emidio +1
We study the Néel to four-fold columnar valence bond solid (cVBS) quantum phase transition in a sign free square lattice model. This is the same kind of transition that for $…
Non-Abelian quasiholes in lattice Moore-Read states and parent Hamiltonians
Sourav Manna, Julia Wildeboer, Germán Sierra +1
This work concerns Ising quasiholes in Moore-Read type lattice wave functions derived from conformal field theory. We commence with constructing Moore-Read type lattice states and…
