Ultrafast Non-Hermitian Skin Effect
Barbara Schneider, Alexander Dikopoltsev, Markus Bestler +5
Topological phases of matter commonly feature protected states at their boundaries. Transferring this protection to time-metamaterials is extremely challenging, as it requires the…
Non-Hermitian topology and skin modes in the continuum via parametric processes
Markus Bestler, Alexander Dikopoltsev, Oded Zilberberg
We demonstrate that Hermitian, nonlocal parametric pairing processes can induce non-Hermitian topology and skin modes, offering a simple alternative to complex bath engineering. Ou…
A Quantum Walk Comb Source at Telecommunication Wavelengths
Bahareh Marzban, Lucius Miller, Alexander Dikopoltsev +3
We demonstrate a quantum walk comb in synthetic frequency space formed by externally modulating a semiconductor optical amplifier operating in the telecommunication wavelength rang…
Quench dynamics of Wannier-Stark states in an active synthetic photonic lattice
Alexander Dikopoltsev, Ina Heckelmann, Mathieu Bertrand +4
Photonic emulators have facilitated the investigation of numerous solid-state phenomena and have contributed to the development of optical devices inspired by quantum mechanics. Al…
