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…

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…
