Optical Tautochrone and Squeezing Dynamics in Nonuniform Lattices

Ioannis Kiorpelidis, Matthias Heinrich, Alexander Szameit +2

We present exact analogies between the tautochrone problem of classical mechanics and the squeezed states of quantum optics to optical lattices. Both phenomena emerge in the same p…

Experimental observation of hyperbolic spacetime dynamics

Jonas Himmel, Coraline Bacq, Krishna Chand Maurya +11

Understanding quantum dynamics in curved spacetime is a central challenge at the intersection of quantum mechanics and gravity. Anti-de-Sitter (AdS) spacetime plays a pivotal role…

Path integral quantization of the electromagnetic field in nonlinear dielectric materials

Arman Kashef, Oscar Perearnau Herrero, Alexander Szameit +2

We construct a quantum theory of light in nonlinear dielectric media with dispersion and absorption. We employ a mesoscopic model for the light-matter interaction that include a fo…

Observation of Joule-Thomson photon-gas expansion

Marco S. Kirsch, Georgios G. Pyrialakos, Richard Altenkirch +9

In recent years, a self-consistent optical thermodynamic framework has emerged that offers a systematic methodology to understand, harness and exploit the complex collective dynami…

Pairing particles into holonomies

Vera Neef, Matthias Heinrich, Tom A. W. Wolterink +1

Holonomies are of great interest to quantum computation and simulation. The geometrical nature of these entities offers increased stability to quantum gates. Furthermore, symmetrie…

Non-Exponential Decay in Finite Photonic Waveguide Arrays

Florian H. Huber, Benedikt Braumandl, Johannes Knörzer +5

Open quantum-system dynamics can follow exponential decay, non-exponential relaxation, or oscillatory dynamics, depending on the system-environment coupling. We study a lattice wit…
