Spintronics and quantum information science are two promising candidates for innovating
information processing technologies. The combination of these two fields enables us to build …

The entanglement entropy of subsystems of typical eigenstates of quantum many-body
Hamiltonians has recently been conjectured to be a diagnostic of quantum chaos and …

Given a statistical ensemble of quantum states, the corresponding Page curve quantifies the
average entanglement entropy associated with each possible spatial bipartition of the …

We study the bipartite von Neumann entanglement entropy and matrix elements of local
operators in the eigenstates of an interacting integrable Hamiltonian (the paradigmatic spin …

We present a systematic geometric framework to study closed quantum systems based on
suitably chosen variational families. For the purpose of (A) real time evolution,(B) excitation …

In noninteracting isolated quantum systems out of equilibrium, local subsystems typically
relax to nonthermal stationary states. In the standard framework, information on the rest of …

In a seminal paper, Page found the exact formula for the average entanglement entropy for a
pure random state. We consider the analogous problem for the ensemble of pure fermionic …

The eigenstate entanglement entropy is a powerful tool to distinguish integrable from
generic quantum-chaotic models. In integrable models, the average eigenstate …

We show that bosonic and fermionic Gaussian states (also known as" squeezed coherent
states") can be uniquely characterized by their linear complex structure $ J $ which is a …

Eigenstates of local many-body interacting systems that are far from spectral edges are
thought to be ergodic and close to being random states. This is consistent with the …
