Reconstructing the polar interface of infinite-layer nickelate thin films

Posted by klaurent Cornell

Kavli Affiliate: Lena F. Kourkoutis | First 5 Authors: Berit H. Goodge, Benjamin Geisler, Kyuho Lee, Motoki Osada, Bai Yang Wang | Summary: Nickel-based superconductors provide a long-awaited experimental platform to explore possible cuprate-like superconductivity. Despite similar crystal structure and $d$ electron filling, these systems exhibit several differences. Nickelates are the most polar layered oxide […]

A pair of Sub-Neptunes transiting the bright K-dwarf TOI-1064 characterised with CHEOPS

Posted by klaurent MIT

Kavli Affiliate: George R. Ricker | First 5 Authors: Thomas G. Wilson, Elisa Goffo, Yann Alibert, Davide Gandolfi, Andrea Bonfanti | Summary: We report the discovery and characterisation of a pair of sub-Neptunes transiting the bright K-dwarf TOI-1064 (TIC 79748331), initially detected in TESS photometry. To characterise the system, we performed and retrieved CHEOPS, TESS, […]

Many-body Hilbert space scarring on a superconducting processor

Posted by klaurent Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Pengfei Zhang, Hang Dong, Yu Gao, Liangtian Zhao, Jie Hao | Summary: Quantum many-body scarring (QMBS) — a recently discovered form of weak ergodicity breaking in strongly-interacting quantum systems — presents opportunities for mitigating thermalization-induced decoherence in quantum information processsing. However, the existing experimental realizations of QMBS […]

Probing quantum many-body scars on a superconducting processor

Posted by klaurent Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Pengfei Zhang, Hang Dong, Yu Gao, Liangtian Zhao, Jie Hao | Summary: Thermalization in complex and strongly interacting quantum many-body systems represents an obstacle to applications. It was recently suggested theoretically that quantum many-body scarring (QMBS) states embedded in the thermalized energy spectrum can overcome this difficulty. […]
