Quantum Motion from Local Transition Susceptibility
Jan Klaers
We characterize quantum motion through the susceptibility of a quantum state to weak localized state conversion. The susceptibility can be related to a passage speed characterizing…
From Quantum Chaos to Classical Chaos via Gain-Induced Measurement Dynamics in a Photon Gas
Violetta Sharoglazova, Marius Puplauskis, Lotte Hof +1
How classical chaos emerges from quantum mechanics remains a central open question, as the unitary evolution of isolated quantum systems forbids exponential sensitivity to initial…
Reaffirming a Challenge to Bohmian Mechanics
Jan Klaers, Violetta Sharoglazova, Marius Puplauskis
In our recent work, we reported the first measurement of the speed of tunnelling particles using a coupled waveguide system. The measured speed is operationally defined through a c…
Particle motion associated with wave function density gradients
Jan Klaers, Violetta Sharoglazova, Chris Toebes
We study the quantum mechanical motion of massive particles in a system of two coupled waveguide potentials, where the population transfer between the waveguides effectively acts a…
Fluctuation dynamics of an open photon Bose-Einstein condensate
Fahri Emre Ozturk, Tim Lappe, Goran Hellmann +5
Bosonic gases coupled to a particle reservoir have proven to support a regime of operation where Bose-Einstein condensation coexists with unusually large particle-number fluctuatio…
