Toward Scalable Many-Body Calculations for Nuclear Open Quantum Systems using the Gamow Shell Model

GSM is a configuration interaction model based on the use of the so-called Berggren basis, which contains bound, resonant and scattering states, so that inter-nucleon correlations are fully taken into account and the asymptotes of extended many-body wave functions are precisely handled.

Many-body scar state intrinsic to periodically driven system: Rigorous results

We exactly prove the existence of many-body scar states in the Floquet eigenstates, by showing the explicit expressions of the wave functions. Expand abstract.

Thouless time analysis of Anderson and many-body localization transitions

Identifying similarities between system size and disorder strength scaling of Thouless time for disordered quantum many-body systems with results for 3D and 5D Anderson models, we argue that the two-parameter scaling breaks down in the vicinity of the transition to the localized phase signalling subdiffusive dynamics.

Extracting many-body correlators of saturated gluons with precision from inclusive photon+dijet final states in deeply inelastic scattering

We highlight the principal results of a computation in the Color Glass Condensate effective field theory (CGC EFT) of the next-to-leading order (NLO) impact factor for inclusive photon+dijet production at Bjorken $x_{\rm Bj} \ll 1$ in deeply inelastic electron-nucleus (e+A DIS) collisions.

Many-body quantum dynamics and induced correlations of Bose polarons

For attractive interspecies couplings, the impurities exhibit a tendency to localize at the origin and remarkably for strong attractions they experience a mutual attraction on the two-body level that is imprinted as a density hump on the bosonic bath. Expand abstract.

Spectral decoupling in many-body quantum chaos

We argue that in a large class of disordered quantum many-body systems the late time dynamics of time-dependent correlation functions is captured by random matrix theory, specifically the energy eigenvalue statistics of the corresponding ensemble of disordered Hamiltonians. Expand abstract.

MCTDH-X: The multiconfigurational time-dependent Hartree method for indistinguishable particles software

The MCTDH-X software solves a set of non-linear coupled working equations that are obtained by applying the variational principle to the Schr\"{o}dinger equation using an ansatz for the wavefunction that is a time-dependent expansion in a set of time-dependent, fully symmetrized or fully anti-symmetrized many-body basis...

Quantum Simulation of Hyperbolic Space with Circuit Quantum Electrodynamics: From Graphs to Geometry

Our analysis also reveals in which sense discrete hyperbolic lattices emulate the continuous geometry of negatively curved space and thus can be used to resolve fundamental open problems at the interface of interacting many-body systems, quantum field theory in curved space, and quantum gravity.

Self-averaging behavior at the metal-insulator transition of many-body quantum systems out of equilibrium

The latter scenario is often found in the vicinity of critical points, such as at the metal-insulator transition of interacting many-body quantum systems. Expand abstract.
