When Higher Resolution Reduces Precision: Quantum Limits of Off-Axis Interferometric Scattering Microscopy
Felix Hitzelhammer, Jonathan Dong, Ulrich Hohenester +1
Coherent interferometric scattering microscopy (iscat) enables nanoparticle tracking on microsecond timescales and with nanometer precision, and has become a key tool in structural…
Bridging Quantum Noise and Classical Electrodynamics with Stochastic Methods
Felix Hitzelhammer, Johannes Stowasser, Lukas Hanschke +7
The development of emerging technologies in quantum optics demands accurate models that faithfully capture genuine quantum effects. Mature semiclassical approaches reach their limi…
Unified simulation platform for interference microscopy
Felix Hitzelhammer, Anežka Dostálová, Ilia Zykov +4
Interferometric scattering microscopy is a powerful technique that enables various applications, such as mass photometry and particle tracking. Here we present a numerical toolbox…
Stochastic correction to the Maxwell-Bloch equations via the positive representation
Johannes Stowasser, Felix Hitzelhammer, Michael A. Schreiber +4
Focusing on two-level atoms, we apply the positive representation to a full-wave mixed bosonic and fermionic system of Jaynes-Cummings type and identify an advantageous degree…
Modeling of Fluctuations in Dynamical Optoelectronic Device Simulations within a Maxwell-Density Matrix Langevin Approach
Johannes Popp, Johannes Stowasser, Michael A. Schreiber +5
We present a full-wave Maxwell-density matrix simulation tool including c-number stochastic noise terms for the modeling of the spatiotemporal dynamics in active photonic devices,…
