Theory of Two-Qubit Spectroscopy of Quantum Many-Body Systems
Hossein Hosseinabadi, Pavel E. Dolgirev, Sarang Gopalakrishnan +3
Multi-qubit quantum sensors are rapidly emerging as platforms that extend the capabilities of conventional single-qubit sensing. In this work we show how suitable pulse sequences a…
Inverse Quantum Simulation for Quantum Material Design
Christian Kokail, Pavel E. Dolgirev, Rick van Bijnen +3
Quantum simulation provides a powerful route for exploring many-body phenomena beyond the capabilities of classical computation. Existing approaches typically proceed in the forwar…
Enhanced coherent terahertz emission from critical superconducting fluctuations in YBaCuO
D. Nicoletti, M. Rosenberg, M. Buzzi +10
Coherent terahertz (THz) emission is emerging as a powerful new tool to probe symmetry breakings in quantum materials. This method relies on second order optical nonlinearities and…
Role of Phase Fluctuation in Dynamic Competition Between Charge Order and Superconductivity in Cuprates
Mingu Kang, Pavel E. Dolgirev, Chao C. Zhang +9
Phase fluctuations are a key factor distinguishing nonthermal (ultrafast) and thermal phase transitions. Charge order in cuprates is characterized by short-range coherence while co…
Probing emergent prethermal dynamics and resonant melting on a programmable quantum simulator
Siva Darbha, Alexey Khudorozhkov, Pedro L. S. Lopes +11
The dynamics of isolated quantum systems following a sudden quench plays a central role in many areas of material science, high-energy physics, and quantum chemistry. Featuring com…
Gap Inhomogeneity in Cuprates: a view from Two-Dimensional Josephson Echo Spectroscopy
Alex Gómez Salvador, Ivan Morera, Marios H. Michael +5
Novel theoretical developments have allowed to connect microscopic disorder in bosonic collective excitations to the signatures in two-dimensional terahertz spectroscopy (Gómez Sa…
