Anomalous Thermal Transport Reveals Weak First-Order Melting of Charge Density Waves in 2H-TaSe2
Han Huang, Jinghang Dai, Joyce Christiansen-Salameh +14
How ordered phases melt in low-dimensional quantum materials remain difficult to resolve because the relevant fluctuations are dynamic and charge neutral. In this work, we show tha…
Quantifying surface losses in superconducting aluminum microwave resonators
Elizabeth Hedrick, Faranak Bahrami, Alexander C. Pakpour-Tabrizi +11
The recent realization of millisecond-scale coherence with tantalum-on-silicon transmon qubits showed that depositing the Al/AlOx/Al Josephson junction in a high purity, ultrahigh…
Beta Tantalum Transmon Qubits with Quality Factors Approaching 10 Million
Atharv Joshi, Apoorv Jindal, Paal H. Prestegaard +9
Tantalum-based transmon qubits are a promising platform for building large-scale quantum processors. So far, these qubits have been made from tantalum films grown exclusively in th…
van der Waals Nanoreactors
Zhaoyi Joy Zheng, Haosen Guan, Danrui Ni +11
Advancing the chemical synthesis of crystals is important for both fundamental research and practical applications of quantum materials. While established bulk-phase and thin-film…
Superconducting Gap Engineering in Tantalum-Alloy-Based Resonators
Chen Yang, Faranak Bahrami, Guangming Cheng +7
Utilizing tantalum (Ta) in superconducting circuits has led to significant improvements, such as high qubit lifetimes and quality factors in both qubits and resonators, underscorin…
Suppression of Intertwined Density Waves in LaNiCuO
Stephen Zhang, Danrui Ni, Ruyi Ke +3
Superconductivity in LaNiO has been reported to emerge upon suppression of intertwined spin and charge density wave (SDW/CDW) order, suggesting a possible connec…
