Quantum logarithmic multifractality
Weitao Chen, Olivier Giraud, Jiangbin Gong +1
Through a combination of rigorous analytical derivations and extensive numerical simulations, this work reports an exotic multifractal behavior, dubbed "logarithmic multifractality…
Epidemic models on homogeneous networks : some analytical results
Louis Bremaud, Olivier Giraud, Denis Ullmo
The ability to actually implement epidemic models is a crucial stake for public institutions, as they may be overtaken by the increasing complexity of current models and sometimes…
Absence of a direct metal to Mott insulator transition for disordered interacting fermions on the Cayley tree
Ankita Chakrabarti, Nicolas Laflorencie, Bertrand Georgeot +2
Interacting fermions in the presence of disorder pose one of the most challenging problems in condensed matter physics, primarily due to the absence of accurate numerical tools. Ou…
Fano Resonance in Excitation Spectroscopy and Cooling of an Optically Trapped Single Atom
Chang Hoong Chow, Boon Long Ng, Vindhiya Prakash +1
Electromagnetically induced transparency (EIT) can be used to cool an atom in a harmonic potential close to the ground state by addressing several vibrational modes simultaneously.…
Randomised benchmarking for characterizing and forecasting correlated processes
Xinfang Zhang, Zhihao Wu, Gregory A. L. White +12
The development of fault-tolerant quantum processors relies on the ability to control noise. A particularly insidious form of noise is temporally correlated or non-Markovian noise.…
Demonstration of a low loss, highly stable and re-useable edge coupler for high heralding efficiency and low g^(2) (0) SOI correlated photon pair sources
Jinyi Du, George F. R. Chen, Hongwei Gao +3
We report a stable, low loss method for coupling light from silicon-on-insulator (SOI) photonic chips into optical fibers. The technique is realized using an on-chip tapered wavegu…
