Inner workings of fractional quantum Hall parent Hamiltonians: A matrix product state point of view

چکیده

We study frustration-free Hamiltonians of fractional quantum Hall (FQH) states from the point view matrix product state (MPS) representation their ground and excited states. There is a wealth solvable models relating to FQH physics, which, however, mostly derived analyzed vantage first-quantized "analytic clustering properties". In contrast, one obtains long-ranged lattice when these are studied in an orbital basis, which natural basis for MPS The connection between MPS-like parent central guiding principle construction models, but thus far, only short-range MPSs finite bond dimension. situation context fundamentally different. Here we expose direct link infinite-bond-dimension structure Laughlin-conformal field theory (CFT) Hamiltonians. While focusing on Laughlin state, generalizations other CFT-MPSs will become transparent.

Model Hamiltonians for the Fractional Quantum Hall E ect

The fractional quantum Hall e ect (FQHE), discovered by Stui and Stormer in 1982, has been the subject of much theoretical and experimental interest since. Whereas the integer case (IQHE) can be understood in terms of single-electron behavior in the presence of a magnetic eld, the FQHE appears to be the result of Coulomb interactions between electrons in the system. Laughlin [1] explained the ...

Matrix Effective Theories of the Fractional Quantum Hall effect

The present understanding of nonperturbative ground states in the fractional quantum Hall effect is based on effective theories of the Jain “composite fermion” excitations. We review the approach based on matrix variables, i.e. D0 branes, originally introduced by Susskind and Polychronakos. We show that the Maxwell-Chern-Simons matrix gauge theory provides a matrix generalization of the quantum...

Non-equilibrium fractional quantum Hall state of light

We investigate the quantum dynamics of systems involving small numbers of strongly interacting photons. Specifically, we develop an efficient method to investigate such systems when they are externally driven with a coherent field. Furthermore, we show how to quantify the many-body quantum state of light via correlation functions. Finally, we apply this method to two strongly interacting cases:...

Topological characterization of fractional quantum Hall ground states from microscopic Hamiltonians.

We show how to numerically calculate several quantities that characterize topological order starting from a microscopic fractional quantum Hall Hamiltonian. To find the set of degenerate ground states, we employ the infinite density matrix renormalization group method based on the matrix-product state representation of fractional quantum Hall states on an infinite cylinder. To study localized q...
