Metastability in the Dissipative Quantum Rabi Model
Da-Wu Xiao, Chong Chen·Nov 26, 2025
The dissipative quantum Rabi model exhibits rich non-equilibrium physics, including a dissipative phase transition from the normal phase to the superradiant phase. In this work, we investigate the stability of the superradiant phase in the presence o...
Phase-Dependent Photon Emission Rates in Quantum Gravity-Induced Entangled States
Chi Zhang·Nov 26, 2025
Quantum entanglement, as one of the fundamental concepts in quantum mechanics, has garnered significant attention over the past few decades for its extraordinary nonlocality. With the advancement of quantum technology, quantum entanglement holds prom...
Floquet thermalization by power-law induced permutation symmetry breaking
Manju C, Uma Divakaran·Nov 26, 2025
Permutation symmetry plays a central role in the understanding of collective quantum dynamics. On the other hand, interactions are rarely uniform in real systems. By introducing power law couplings that algebraically decay with the distance between t...
The effects of decoherence on Fermi's golden rule
Caihong Zheng, Fan Zheng·Nov 26, 2025
Fermi's golden rule which describes the transition rates between two electronic levels under external stimulations is used ubiquitously in different fields of physics. The original Fermi's golden rule was derived from perturbative time-dependent Schr...
Impact of the valence band on Rydberg excitons in cuprous oxide quantum wells
Niklas Scheuler, Jörg Main, Patric Rommel +3 more·Nov 25, 2025
The complex valence band structure of bulk cuprous oxide necessitates going beyond the parabolic approximation to precisely estimate exciton binding energies. The same is true for excitons in cuprous oxide quantum wells, for which many effects have b...
Escaping AB caging via Floquet engineering: photo-induced long-range interference in an all-band-flat model
Aamna Ahmed, Mónica Benito, Beatriz Pérez-González·Nov 25, 2025
Flat-band lattices hosting compact localized states are highly sensitive to external modulation, and the tailored design of a perturbation to imprint specific features becomes relevant. Here we show that periodic driving in the high-frequency regime ...
Generation of Ultrahigh Anomalous Hall Conductivities via Optimally Prepared Topological Floquet States
Andrew Cupo, Hai-Ping Cheng, Chandrasekhar Ramanathan +1 more·Nov 25, 2025
Ultrafast quantum matter experiments have validated predictions from Floquet theory - notably, the dynamical modification of the electronic band structure and the light-induced anomalous Hall effect, via monotonic modulation of the driving amplitude....
Generalized Landau Paradigm for quantum phases and phase transitions
Xie Chen·Nov 24, 2025
The Landau paradigm is a central dogma for understanding phase and phase transitions in condensed matter systems, yet for decades it has been known that a variety of quantum phases exist beyond the framework. Is there a more general framework that pr...
Exact Solutions for the Kemmer Oscillator in 1+1 Rindler Coordinates
T. Rouabhia, A. Boumali·Nov 24, 2025
This work presents exact solutions of the Kemmer equation for spin-1 particles in $(1+1)$-dimensional Rindler spacetime, motivated by the need to understand vector bosons under uniform acceleration, including non-inertial effects and the Unruh temper...
Synergistic Effects of Detuning and Auxiliary Qubits on Quantum Synchronization
Amir Hossein Houshmand Almani, Ali Mortezapour, Alireza Nourmandipour·Nov 24, 2025
We investigate how detuning and auxiliary qubits collaboratively enhance quantum synchronization in a dissipative multi-qubit system that is coupled to a structured reservoir. Our findings indicate that while detuning is ineffective in Markovian envi...
A demonstration that classical gravity does not produce entanglement
Mike D. Schneider, Nick Huggett, Niels Linnemann·Nov 24, 2025
Once again, dispute has arisen over the interpretation of proposed quantum information theory experiments to probe the quantum nature of gravity by testing for gravitationally induced entanglement (GIE) between two spatially separated massive particl...
Synchronized Aharonov-Bohm Motifs via Engineered Dissipation
Christopher W. Wächtler, Gloria Platero·Nov 24, 2025
The interplay between external gauge fields and lattice geometry can induce extreme localization dynamics through complete destructive interference. We show that combining this flux-induced localization with engineered dissipation leads to robust spi...
Dispersive detection of single microwave photons with quantum dots
Stephanie Matern, A. Biella, P. Scarlino +2 more·Nov 24, 2025
Within a circuit quantum electrodynamics architecture, we theoretically investigate the detection of a single propagating microwave photon traveling through a resonant microwave cavity dispersively interacting with a double quantum dot tunnel-coupled...
Attosecond-resolved quantum fluctuations of light and matter
Matan Even Tzur, Chen Mor, Noa Yaffe +10 more·Nov 23, 2025
Until recently, attosecond optical spectroscopy and quantum optics evolved along non-overlapping directions. In attosecond science, attosecond pulses have been regarded as classical waves, applied to probe electron dynamics on their natural time scal...
Kicked-Ising Quantum Battery
Sebastián V. Romero, Xi Chen, Yue Ban·Nov 21, 2025
Quantum batteries (QBs) have emerged as promising candidates capable of outperforming classical counterparts by utilizing entangled operators. Spin chains, in particular, exhibit unique {charging} properties across diverse settings. Here, we introduc...
Entanglement and correlations between local observables in de Sitter spacetime
Patricia Ribes-Metidieri, Ivan Agullo, Béatrice Bonga·Nov 21, 2025
Studies of quantum field entanglement in de Sitter space based on the von Neumann entropy of local patches have concluded that curvature enhances entanglement between regions and their complements. Similar conclusions about entanglement enhancement h...
Enhancing Infrared Laser Dissociation of Molecules with the Electromagnetic Vacuum
Johan F. Triana, Felipe Herrera·Nov 21, 2025
Controlling bond breaking is a long-standing goal in molecular physics. Infrared nanocavities are currently being developed for reaching exotic coupling regimes of cavity QED with a few molecules, but it is not well understood how chemical reactions ...

We report the first experimental realization of a scalable basic cell for quantum routing, enabling coherent control and exchange of microwave photons between two spatially separated superconducting waveguides coupled via a single transmon qubit. The...
50-km fiber interferometer for testing gravitational signatures in quantum interference
Haocun Yu, Dorotea Macri, Thomas Morling +10 more·Nov 21, 2025
Quantum mechanics and general relativity are the foundational pillars of modern physics, yet experimental tests that combine the two frameworks remain rare. Measuring optical phase shifts of massless photons in a gravitational potential provides a un...
