Effect of Single Impurity on Free Fermion Entanglement Entropy
Mohammad Pouranvari, Kun Yang, Alexander Seidel
The one-dimensional free Fermi gas is a prototype conformally invariant system, whose entanglement properties are well-understood. In this work, the effects of a single impurity on…
Zero modes, Bosonization and Topological Quantum Order: The Laughlin State in Second Quantization
Tahereh Mazaheri, Gerardo Ortiz, Zohar Nussinov +1
We introduce a "second-quantized" representation of the ring of symmetric functions to further develop a purely second-quantized -- or "lattice" -- approach to the study of zero mo…
Algebraic approach to the study of zero modes of Haldane pseudopotentials
Li Chen, Alexander Seidel
We consider lattice Hamiltonians that arise from putting Haldane pseudopotentials into a second quantized or "guiding-center-only" form. These are fascinating examples for frustrat…
Thin torus perturbative analysis of elementary excitations in the Gaffnian and Haldane-Rezayi quantum Hall states
Amila Weerasinghe, Alexander Seidel
We present a systematic perturbative approach to study excitations in the thin cylinder/torus limit of the quantum Hall states. The approach is applied to the Haldane-Rezayi and Ga…
