Quantized pumping in disordered nonlinear Thouless pumps
Abhijit P. Chaudhari, Marius Jürgensen, Mikael C. Rechtsman
We investigate the dynamics of nonlinear optical Thouless pumps in the presence of disorder, using optical waveguide arrays. It was previously known that the displacement of solito…
Airy Resonances in Photonic Crystal Superpotentials
Zeyu Zhang, Brian Gould, Maria Barsukova +1
Airy wavefunctions are associated with one of the simplest scenarios in wave mechanics: a quantum bouncing ball. In other words, they are the eigenstates of the time-independent Sc…
Stealthy-Hyperuniform Wave Dynamics in Two-Dimensional Photonic Crystals
Maria Barsukova, Zeyu Zhang, Brian Gould +5
Hyperuniform structures are spatial patterns whose fluctuations disappear on long length scales, making them effectively homogeneous when observed from afar. Mathematically, this m…
Multi-band fractional Thouless pumps
Marius Jürgensen, Jacob Steiner, Gil Refael +1
Quantization of particle transport lies at the heart of topological physics. In Thouless pumps - dimensionally reduced versions of the integer quantum Hall effect - quantization is…
Quantized dynamical pumping via dissipation in a mechanical Thouless pump
Marius Jürgensen, Mikael C. Rechtsman
Thouless pumps are time-periodic one-dimensional systems that capture the physics of the two-dimensional quantum Hall effect via the quantized pumping of particles under adiabatic…
