Topological models in rotationally symmetric quasicrystals
Callum W. Duncan, Sourav Manna, Anne E. B. Nielsen
We investigate the physics of quasicrystalline models in the presence of a uniform magnetic field, focusing on the presence and construction of topological states. This is done by…
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…
Anyons and Fractional Quantum Hall Effect in Fractal Dimensions
Sourav Manna, Biplab Pal, Wei Wang +1
The fractional quantum Hall effect is a paradigm of topological order and has been studied thoroughly in two dimensions. Here, we construct a new type of fractional quantum Hall sy…
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…
Generalized Triple-Component Fermions: Lattice Model, Fermi arcs, and Anomalous Transport
Snehasish Nandy, Sourav Manna, Dumitru Calugaru +1
We generalize the construction of time-reversal symmetry-breaking triple-component semimetals, transforming under the pseudospin-1 representation, to arbitrary (anti-)monopole char…
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…
