Correlated states controlled by tunable van Hove singularity in moiré WSe2

Kavli Affiliate: Jie Shan | First 5 Authors: Patrick Knüppel, Jiacheng Zhu, Yiyu Xia, Zhengchao Xia, Zhongdong Han | Summary: Twisted bilayers of transition metal dichalcogenide semiconductors have enabled the discovery of superconductivity, ferromagnetism, correlated insulators and a series of new topological phases of matter. However, the connection between these electronic phases and the underlying […]

Self-dispersion-managed adiabatic frequency conversion

Kavli Affiliate: Jeffrey Moses | First 5 Authors: Dylan Heberle, Noah Flemens, Connor Davis, Philippe Lassonde, Adrien Leblanc | Summary: Dispersion management of few-cycle pulses is crucial for ultrafast optics and photonics. Often, nontrivial dispersion is compensated using complex optical systems or minimized through careful design of waveguides. Here, we present dispersion-managed adiabatic frequency conversion […]

Unconventional superconductivity in twisted bilayer WSe2

Kavli Affiliate: Jie Shan | First 5 Authors: Yiyu Xia, Zhongdong Han, Kenji Watanabe, Takashi Taniguchi, Jie Shan | Summary: Moir’e materials have enabled the realization of flat electron bands and quantum phases that are driven by strong correlations associated with flat bands. Superconductivity has been observed, but solely, in graphene moir’e materials. The absence […]

Spiral Spin Liquid Noise

Kavli Affiliate: J. C. Seamus Davis | First 5 Authors: Hiroto Takahashi, Chun-Chih Hsu, Fabian Jerzembeck, Jack Murphy, Jonathan Ward | Summary: An emerging concept for identification of different types of spin liquids is through the use of spontaneous spin noise. Here we develop spin noise spectroscopy for spin liquid studies by considering Ca$_{10}$Cr$_7$O$_{28}$, a […]

Dynamical Freezing in Exactly Solvable Models of Driven Chaotic Quantum Dots

Kavli Affiliate: Debanjan Chowdhury | First 5 Authors: Haoyu Guo, Rohit Mukherjee, Debanjan Chowdhury, , | Summary: The late-time equilibrium behavior of generic interacting models is determined by the coupled hydrodynamic equations associated with the globally conserved quantities. In the presence of an external time-dependent drive, non-integrable systems typically thermalize to an effectively infinite-temperature state, […]

Excitation-Dependent Features and Artifacts in 2-D Terahertz Spectroscopy

Kavli Affiliate: Ankit Disa | First 5 Authors: Albert Liu, Ankit Disa, , , | Summary: Recently, two-dimensional terahertz spectroscopy (2DTS) has attracted increasing attention for studying complex solids. A number of recent studies have applied 2DTS either with long pulses or away from any material resonances, situations that yield unconventional 2DTS spectra that are […]

Jamming memory into acoustically trained dense suspensions under shear

Kavli Affiliate: Itai Cohen | First 5 Authors: Edward Y. X. Ong, Anna R. Barth, Navneet Singh, Meera Ramaswamy, Abhishek Shetty | Summary: Systems driven far from equilibrium often retain structural memories of their processing history. This memory has, in some cases, been shown to dramatically alter the material response. For example, work hardening in […]
