Collective decay of interacting bosons

Bennet Windt, Lorenzo Rossi, Alexander V. Poshakinskiy +2

We study a bosonic analog of the paradigmatic Dicke model of superradiance, comprising interacting bosonic modes subject to fully symmetric collective decay. Depending on the inter…

Many-Body Entanglement in Solid-State Emitters

Emma Daggett, Christian M. Lange, Bennet Windt +23

The preparation and control of quantum states lie at the heart of quantum information science (QIS). Recent advances in solid-state quantum emitters (QEs) and nanophotonics have tr…

Mesoscopic cavity quantum electrodynamics with phase-disordered emitters in a Kerr nonlinear resonator

Daniil M. Lukin, Bennet Windt, Miguel Bello +13

The field of cavity quantum electrodynamics (QED) has seen a recent resurgence of interest in few- and many-body physics owing to the realization that the breaking of symmetries an…

Effects of retardation on many-body superradiance in chiral waveguide QED

Bennet Windt, Miguel Bello, Daniel Malz +1

We study the superradiant decay of a chain of atoms coupled to a chiral waveguide, focusing on the regime of non-negligible photon propagation time. Using an exact master equation…

Fermionic matter-wave quantum optics with cold-atom impurity models

Bennet Windt, Miguel Bello, Eugene Demler +1

Motivated by recent cold-atom realisations of matter-wave waveguide QED, we study simple fermionic impurity models and discuss fermionic analogues of several paradigmatic phenomena…

The maximum refractive index of an atomic crystal $\unicode{x2013}$ from quantum optics to quantum chemistry

Francesco Andreoli, Bennet Windt, Stefano Grava +4

All known optical materials have an index of refraction of order unity. Despite the tremendous implications that an ultrahigh index could have for optical technologies, little rese…

Squeezing Quantum Many-Body Scars

Bennet Windt, Hannes Pichler

We develop an analytical approach for the description of quantum many-body scars in PXP models. We show that the scarred dynamics in the PXP model on a complete bipartite graph can…

Long-distance entanglement of purification and reflected entropy in conformal field theory

Hugo A. Camargo, Lucas Hackl, Michal P. Heller +2

Quantifying entanglement properties of mixed states in quantum field theory via entanglement of purification and reflected entropy is a new and challenging subject. In this work, w…

Local optimization on pure Gaussian state manifolds

Bennet Windt, Alexander Jahn, Jens Eisert +1

We exploit insights into the geometry of bosonic and fermionic Gaussian states to develop an efficient local optimization algorithm to extremize arbitrary functions on these famili…

Entanglement and Complexity of Purification in (1+1)-dimensional free Conformal Field Theories

Hugo A. Camargo, Lucas Hackl, Michal P. Heller +3

Finding pure states in an enlarged Hilbert space that encode the mixed state of a quantum field theory as a partial trace is necessarily a challenging task. Nevertheless, such puri…
