Hilbert space fragmentation from lattice geometry
Pieter H. Harkema, Michael Iversen, Anne E. B. Nielsen
The eigenstate thermalization hypothesis describes how isolated many-body quantum systems reach thermal equilibrium. However, quantum many-body scars and Hilbert space fragmentatio…
Tower of two-dimensional scar states in a localized system
Michael Iversen, Jens H. Bardarson, Anne E. B. Nielsen
The eigenstate thermalization hypothesis describes how most isolated many-body quantum systems reach thermal equilibrium. However, the hypothesis is violated by phenomena such as m…
Approximate Hofstadter- and Kapit-Mueller-like parent Hamiltonians for Laughlin states on fractals
Błażej Jaworowski, Michael Iversen, Anne E. B. Nielsen
Recently, it was shown that fractional quantum Hall states can be defined on fractal lattices. Proposed exact parent Hamiltonians for these states are nonlocal and contain three-si…
Tower of quantum scars in a partially many-body localized system
Michael Iversen, Anne E. B. Nielsen
Isolated quantum many-body systems are often well-described by the eigenstate thermalization hypothesis. There are, however, mechanisms that cause different behavior: many-body loc…
Escaping many-body localization in an exact eigenstate
Michael Iversen, N. S. Srivatsa, Anne E. B. Nielsen
Isolated quantum systems typically follow the eigenstate thermalization hypothesis, but there are exceptions, such as many-body localized (MBL) systems and quantum many-body scars.…
State transfer in an inhomogeneous spin chain
Michael Iversen, Rafael Emilio Barfknecht, Angela Foerster +1
We present an analytical study of state transfer in a spin chain in the presence of an inhomogeneous set of exchange coefficients. We initially consider the homogeneous case and de…
