Bogolyubov excitons as a microscopic origin of two-level systems
Andrey Grankin, Victor Galitski
Two-level systems (TLS) are a leading source of decoherence and dielectric loss in Josephson-junction qubits, yet their microscopic origin remains unresolved. We propose an intrins…
Signatures of quantum chaos in phonon-polariton billiards
Yinan Dong, Felix Liu, Ekrem Demirboga +11
We use scanning near-field optical microscopy to image hyperbolic phonon polaritons in hexagonal boron nitride (hBN) billiards with integrable and chaotic geometries. In Sinai bill…
Tunable viscosity across the BCS-BEC crossover
Yunxiang Liao, Andrey Grankin, Archisman Panigrahi +2
Tunable interactions make ultracold quantum gases a unique platform for exploring hydrodynamic properties in the strongly correlated regime. Of particular interest are turbulent fl…
Fluctuation engineering in cavity quantum materials
Hope M Bretscher, Lorenzo Graziotto, Marios H Michael +14
Coupling tailored electromagnetic fluctuations to materials provides a resource for controlling correlated quantum matter. By structuring the frequency, spatial, and modal distribu…
Fractional Chern insulator edges: crystalline effects and optical measurements
Yan-Qi Wang, Johannes Motruk, Andrey Grankin +1
Edge states of chiral topologically ordered phases are commonly described by chiral Luttinger liquids, effective theories that are exact only in the hydrodynamic limit. Motivated b…
Enhanced Cooper pairing in nano-patterned metals
Masoud Mohammadi-Arzanagh, Andrey Grankin, Victor Galitski +1
Nano-patterning has been shown to be a powerful tool for manipulating the vibrational modes of elastic structures, with applications such as optical-mechanical mode coupling. Inspi…
