Globally optimal control of quantum dynamics
Denys I. Bondar, Llorenc Balada Gaggioli, Georgios Korpas +3
Optimization of constrained quantum control problems powers quantum technologies. This task becomes very difficult when these control problems are nonconvex and plagued with dense…

Super-sensing: 100-Fold enhancement in THz time-domain spectroscopy contrast via superoscillating waveform shaping
Peisong Peng, Dusty R. Lindberg, Gerard McCaul +2
Superoscillations are a phenomenon where a band-limited wave may locally oscillate faster than its highest Fourier component. They are a product of destructive interference between…

Solvated electrons in polar liquids as epsilon-near-zero materials tunable in the terahertz frequency range
Matthias Runge, Michael Woerner, Denys I. Bondar +1
Electrons in polar liquids give rise to a polaron resonance at a terahertz (THz) frequency ν_0 depending on electron concentration. The impact of this resonance on light propagati…
