Mitigated barren plateaus in the time-nonlocal optimization of analog quantum-algorithm protocols
Lukas Broers, Ludwig Mathey
Quantum machine learning has emerged as a promising utilization of near-term quantum computation devices. However, algorithmic classes such as variational quantum algorithms have b…
Superfluidity of a laser-stirred Bose-Einstein condensate
Hannes Kiehn, Vijay Pal Singh, Ludwig Mathey
We study superfluidity of a cigar-shaped Bose-Einstein condensate (BEC) by stirring it with a Gaussian potential oscillating back and forth along the axial dimension of the condens…
Frequency dependence of the light-induced Hall effect in dissipative graphene
M. Nuske, L. Mathey
We determine the Hall conductivity of light-driven graphene, with specific focus on its frequency dependence, and compare it to the static effective approximation, based on Floquet…
Cooper problem in a cuprate lattice
Ali Sanayei, Ludwig Mathey
We solve the Cooper problem in a cuprate lattice by utilizing a three-band model. We determine the ground state of a Cooper pair for repulsive on-site interactions, and demonstrate…
Terahertz amplifiers based on gain reflectivity in cuprate superconductors
Guido Homann, Jayson G. Cosme, Ludwig Mathey
We demonstrate that parametric driving of suitable collective modes in cuprate superconductors results in a reflectivity for frequencies in the low terahertz regime. We propo…
Detecting light-induced Floquet band gaps of graphene via trARPES
Lukas Broers, Ludwig Mathey
We propose a realistic regime to detect the light-induced topological band gap in graphene via time-resolved angle-resolved photoelectron spectroscopy (trARPES), that can be achiev…
