Electron Correlation Enables Phase-Coherent One-Attosecond Pulse Trains
Andrés Marchisio, Isobel McSweeney, Paraskevas Tzallas +2
Attosecond synthesis is ultimately a phase problem: a broad spectrum produces an ultrashort waveform only if its harmonics remain phase-locked. We show theoretically that correlate…
Weak measurement in strong laser field physics
Philipp Stammer, Javier Rivera-Dean, Marcelo F. Ciappina +1
The advantage of attosecond measurements is the possibility of time-resolving ultrafast quantum phenomena of electron dynamics. Many such measurements are of interferometric nature…
Ultrafast quantum light uncertainty dynamics in real time
Mohamed Sennary, Javier Rivera-Dean, Mohamed ElKabbash +3
Advancements in quantum optics and squeezed light generation have transformed various domains of quantum science and technology. However, real-time quantum dynamics remain an under…
Topological phase transitions via attosecond x-ray absorption spectroscopy
Juan F. P. Mosquera, Giovanni Cistaro, Mikhail Malakhov +6
We present a numerical experiment that demonstrates the possibility to capture topological phase transitions via an x-ray absorption spectroscopy scheme. We consider a Chern insula…
Metrological robustness of high photon number optical cat states
Philipp Stammer, Tomás Fernández Martos, Maciej Lewenstein +1
In the domain of quantum metrology, cat states have demonstrated their utility despite their inherent fragility with respect to losses. Here, we introduce noise robust optical cat…
