Efficient quantum transport in disordered Floquet networks
Hlér Kristjánsson, Jonathan Brugger, Gabriel Dufour +2
We propose a mechanism for fast and efficient quantum transport through disordered networks with variable on-site energies, inspired by photosynthetic complexes. The mechanism reli…
Thermodynamic state variables from a minimal set of quantum constituents
Uwe Holm, Hans-Peter Weber, Morgan Berkane +4
We show how the macroscopic state variables pressure, entropy and temperature of equilibrium thermodynamics can be consistently derived from the (quantum) chaotic spectral structur…
Optimally driving multi-photon transitions in the perturbative single-mode regime
Frieder Lindel, Stefan Yoshi Buhmann, Andreas Buchleitner +1
The rate of -photon transitions in matter, induced by an incident light field, depends on the field's th order coherence function. Consequently, the coherence properties of t…
Position-Resolved Resonance Quantization for Lossy Cavities
Lucas Weitzel, Andreas Buchleitner, Dominik Lentrodt
Modern experiments in resonators are moving to ever more extreme quantum regimes, posing major challenges to established theoretical approaches, such as so-called few-mode models.…
Dipole-Dipole Interactions of Floquet States
Tim Ehret, Vyacheslav Shatokhin, Andreas Buchleitner
We formulate a Floquet-Markov Lindblad master equation for translationally cold two-level atoms driven by a strong monochromatic wave and coupled to a common electromagnetic bath.…
Anisotropic fluorescence signals retarded dipole-dipole interactions in a thermal atomic cloud
Vyacheslav Shatokhin, Friedemann Landmesser, Mario Niebuhr +3
We experimentally observe and theoretically explain anisotropic multiple quantum coherence signals in the fluorescence from dilute thermal potassium vapors, at room temperature and…
Testing Born's rule via photoionization of helium
Peter Robert Förderer, Andreas Buchleitner, David Busto +1
It is shown how state-of-the-art attosecond photoionization experiments can test Born's rule -- a postulate of quantum mechanics -- via the so-called Sorkin test. A simulation of t…
How to seed ergodic dynamics of interacting bosons under conditions of many-body quantum chaos
Lukas Pausch, Edoardo G. Carnio, Andreas Buchleitner +1
We demonstrate how the initial state of ultracold atoms in an optical lattice controls the emergence of ergodic dynamics as the underlying spectral structure is tuned into the quan…
Two-particle tunneling and the impact of interaction
Jonathan Brugger, Christoph Dittel, Andreas Buchleitner
We analyze the tunneling of two bosons in a double-well, for contact, soft-, and hard-core Coulomb interaction of tunable strength. Transitions from correlated to uncorrelated tunn…
Fourier analysis of many-body transition amplitudes and states
Gabriel Dufour, Andreas Buchleitner
We decompose the counting statistics of many-body interference experiments into contributions associated with distinct irreducible exchange symmetries. To do so, we perform a Fouri…
Machine-learning certification of multipartite entanglement for noisy quantum hardware
Andreas J. C. Fuchs, Eric Brunner, Jiheon Seong +5
Entanglement is a fundamental aspect of quantum physics, both conceptually and for its many applications. Classifying an arbitrary multipartite state as entangled or separable -- a…
Entanglement structures in disordered chains of nitrogen-vacancy centers
Alexander M. Minke, Andreas Buchleitner, Edoardo G. Carnio
A recent study [Phys. Rev. B 17 174111 (2022)] has hypothesized the assembly, along a specific type of one-dimensional defects of diamond, of chains of nitrogen-vacancy (NV) center…
Data-driven approach to mixed-state multipartite entanglement characterisation
Eric Brunner, Aaron Xie, Gabriel Dufour +1
We develop a statistical framework, based on a manifold learning embedding, to extract relevant features of multipartite entanglement structures of mixed quantum states from the me…
