Eigenstate condensation in quantum systems with finite-dimensional Hilbert spaces

Christopher David White, Michael Winer, Noam Bernstein

Random quantum states drawn from the Haar ensemble with a constraint on the energy expectation value $E_{\mathrm{av}}=⟨\ddot{I}ˆ|H|\ddot{I}ˆ⟩$ display \textit{eigenstate conden…
