Exceptional Points, Lasing, and Coherent Perfect Absorption in Floquet Scattering Systems
David Globosits, Puneet Garg, Jakob Hüpfl +4
Periodically time-varying media, known as photonic time crystals (PTCs), provide a promising platform for observing unconventional wave phenomena. We analyze the scattering of elec…
Detecting and Focusing on a Nonlinear Target in a Complex Medium
Antton Goïcoechea, Jakob Hüpfl, Stefan Rotter +2
Wavefront shaping techniques allow waves to be focused on a diffraction-limited target deep inside disordered media. To identify the target position, a guidestar is required that t…
Pseudounitary Floquet scattering matrix for wave-front shaping in time-periodic photonic media
David Globosits, Jakob Hüpfl, Stefan Rotter
The physics of waves in time-varying media provides numerous opportunities for wave control that are unattainable with static media. In particular, Floquet systems with a periodic…
Continuity Equation for the Flow of Fisher Information in Wave Scattering
Jakob Hüpfl, Felix Russo, Lukas M. Rachbauer +4
Using waves to explore our environment is a widely used paradigm, ranging from seismology to radar technology, and from bio-medical imaging to precision measurements. In all of the…
Optimal Cooling of Multiple Levitated Particles: Theory of Far-Field Wavefront-Shaping
Jakob Hüpfl, Nicolas Bachelard, Markus Kaczvinszki +3
The opportunity to manipulate small-scale objects pushes us to the limits of our understanding of physics. Particularly promising in this regard is the interdisciplinary field of l…
Optimal Cooling of Multiple Levitated Particles through Far-Field Wavefront-Shaping
Jakob Hüpfl, Nicolas Bachelard, Markus Kaczvinszki +3
Light forces can be harnessed to levitate mesoscopic objects and cool them down towards their motional quantum ground state. Significant roadblocks on the way to scale up levitatio…
