Multimode Phonon-Polaritons in Lead-Halide Perovskites in the Ultrastrong Coupling Regime
Dasom Kim, Jin Hou, Geon Lee +14
Phonons play a central role in fundamental solid-state phenomena, including superconductivity, Raman scattering, and symmetry-breaking phases. Harnessing phonons to control these e…
Nonlinearity of the Fidelity in Open Qudit Systems: Gate and Noise Dependence in High-dimensional Quantum Computing
Jean-Gabriel Hartmann, Denis Janković, Rémi Pasquier +2
High-dimensional quantum computing has generated significant interest due to its potential to address scalability and error correction challenges faced by traditional qubit-based s…
Open quantum system simulation of time and frequency resolved spectroscopy
Tobias Kramer
The dynamics of excitonic energy transfer in molecular complexes triggered by interaction with laser pulses offers a unique window into the underlying physical processes. The absor…
Relaxation to quantum equilibrium and the Born rule in Nelson's stochastic dynamics
Vincent Hardel, Paul-Antoine Hervieux, Giovanni Manfredi
Nelson's stochastic quantum mechanics provides an ideal arena to test how the Born rule is established from an initial probability distribution that is not identical to the square…
Noisy Qudit vs Multiple Qubits : Conditions on Gate Efficiency for Enhancing Fidelity
Denis Janković, Jean-Gabriel Hartmann, Mario Ruben +1
Today, multiple new platforms are implementing qudits, -level quantum bases of information, for Quantum Information Processing (QIP). It is therefore crucial to study their effi…
Out-of-time-order correlators and quantum chaos
Ignacio García-Mata, Rodolfo A. Jalabert, Diego A. Wisniacki
Quantum Chaos has originally emerged as the field which studies how the properties of classical chaotic systems arise in their quantum counterparts. The growing interest in quantum…
Pseudo-PT symmetric Dirac equation : effect of a new mean spin angular momentum operator on Gilbert damping
Y. Bouguerra, S. Mehani, K. Bechane +2
The pseudo-PT symmetric Dirac equation is proposed and analyzed by using a non-unitary Foldy-Wouthuysen transformations. A new spin operator PT symmetric expectation value (called…
Rise and fall, and slow rise again, of operator entanglement under dephasing
David Wellnitz, Guillermo Preisser, Vincenzo Alba +2
The operator space entanglement entropy, or simply 'operator entanglement' (OE), is an indicator of the complexity of quantum operators and of their approximability by Matrix Produ…
Logical Entropy and Negative Probabilities in Quantum Mechanics
Giovanni Manfredi
The concept of Logical Entropy, , where the are normalized probabilities, was introduced by David Ellerman in a series of recent papers. Although…
Disorder enhanced vibrational entanglement and dynamics in polaritonic chemistry
David Wellnitz, Guido Pupillo, Johannes Schachenmayer
Collectively coupling molecular ensembles to a cavity has been demonstrated to modify chemical reactions akin to catalysis. Theoretically understanding this experimental finding re…
Probing quantum effects with classical stochastic analogs
Rémi Goerlich, Giovanni Manfredi, Paul-Antoine Hervieux +2
We propose a method to construct a classical analog of an open quantum system, namely a single quantum particle confined in a potential well and immersed in a thermal bath. The cla…
A quantum optics approach to photoinduced electron transfer in cavities
David Wellnitz, Guido Pupillo, Johannes Schachenmayer
We study a simple model for photoinduced electron transfer reactions for the case of many donor-acceptor pairs that are collectively and homogeneously coupled to a photon mode of a…
Signatures of quantum chaos transition in short spin chains
Emiliano M. Fortes, Ignacio García-Mata, Rodolfo A. Jalabert +1
The non-integrability of quantum systems, often associated with chaotic behavior, is a concept typically applied to cases with a high-dimensional Hilbert space Among different indi…
Observation of Cooperative Electronic Quantum Tunneling: Increasing Accessible Nuclear States in a Molecular Qudit
Eufemio Moreno-Pineda, Svetlana Klyatskaya, Ping Du +4
As an extension of two-level quantum bits (qubits), multilevel systems, so-called qudits, where d represents the Hilbert space dimension, have been predicted to reduce the number o…
Dark state semilocalization of quantum emitters in a cavity
Thomas Botzung, David Hagenmüller, Stefan Schütz +3
We study a disordered ensemble of quantum emitters collectively coupled to a lossless cavity mode. The latter is found to modify the localization properties of the "dark" eigenstat…
Adiabatic elimination for ensembles of emitters in cavities with dissipative couplings
David Hagenmüller, Stefan Schütz, Guido Pupillo +1
We consider an ensemble of cavity-coupled two-level emitters interacting via full (coherent and dissipative) dipole-dipole interactions. Using an adiabatic elimination procedure we…
Glassy dynamics in a disordered Heisenberg quantum spin system
A. Signoles, T. Franz, R. Ferracini Alves +4
Understanding the dynamics of strongly interacting disordered quantum systems is one of the most challenging problems in modern science, due to features such as the breakdown of th…

Emiliano M. Fortes, Ignacio García-Mata, Rodolfo A. Jalabert +1
Out-of-time-order correlators (OTOCs) have been proposed as a probe of chaos in quantum mechanics, on the basis of their short-time exponential growth found in some particular set-…
Ensemble-induced strong light-matter coupling of a single quantum emitter
Stefan Schütz, Johannes Schachenmayer, David Hagenmüller +6
We discuss a technique to strongly couple a single target quantum emitter to a cavity mode, which is enabled by virtual excitations of a nearby mesoscopic ensemble of emitters. A c…
