Supercurrent mediated by helical edge modes in bilayer graphene

Kavli Affiliate: Srijit Goswami | First 5 Authors: Prasanna Rout, Nikos Papadopoulos, Fernando PeƱaranda, Kenji Watanabe, Takashi Taniguchi | Summary: Bilayer graphene encapsulated in tungsten diselenide can host a weak topological phase with pairs of helical edge states. The electrical tunability of this phase makes it an ideal platform to investigate unique topological effects at […]

Emergence of a spin microemulsion in spin-orbit coupled Bose-Einstein condensates

Kavli Affiliate: Leon Balents | First 5 Authors: Ethan C. McGarrigle, Kris T. Delaney, Leon Balents, Glenn H. Fredrickson | Summary: Recent experiments have shown how the interplay between Bose statistics and spin-orbit coupling (SOC) can lead to superfluid liquid crystalline (stripe) analogues in cold atomic gases. For isotropic SOC in two spatial dimensions, a […]

Emergence of a spin microemulsion in spin-orbit coupled Bose-Einstein condensates

Kavli Affiliate: Leon Balents | First 5 Authors: Ethan C. McGarrigle, Kris T. Delaney, Leon Balents, Glenn H. Fredrickson, | Summary: We report the first observation of a “spin microemulsion”– a phase with undulating spin domains resembling classical bicontinuous oil-water-surfactant emulsions — in two-dimensional systems of spinor Bose-Einstein condensates with isotropic Rashba spin-orbit coupling. Using […]

Detecting Exoplanets Closer to Stars with Moderate Spectral Resolution Integral-Field Spectroscopy

Kavli Affiliate: Bruce Macintosh | First 5 Authors: Shubh Agrawal, Jean-Baptiste Ruffio, Quinn M. Konopacky, Bruce Macintosh, Dimitri Mawet | Summary: While radial velocity surveys have demonstrated that the population of gas giants peaks around $3~text{au}$, the most recent high-contrast imaging surveys have only been sensitive to planets beyond $sim~10~text{au}$. Sensitivity at small angular separations […]

Duality Origami: Emergent Ensemble Symmetries in Holography and Swampland

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Meer Ashwinkumar, Jacob M. Leedom, Masahito Yamazaki, , | Summary: We discuss interrelations between several ideas in quantum gravity. One is the Swampland program, which states that a low-energy effective field theory should satisfy non-trivial constraints to have an ultraviolet (UV) completion in quantum gravity. Another is […]

Duality Origami: Emergent Ensemble Symmetries in Holography and Swampland

Kavli Affiliate: Masahito Yamazaki | First 5 Authors: Meer Ashwinkumar, Jacob M. Leedom, Masahito Yamazaki, , | Summary: We discuss the interrelations between several ideas in quantum gravity — holography, the Swampland, and the concept of ensemble averaging. To do so, we study ensemble averages of Narain-type theories associated with general even quadratic forms and […]

Gravitational Positivity for Phenomenologists: Dark Gauge Boson in the Swampland

Kavli Affiliate: Satoshi Shirai | First 5 Authors: Katsuki Aoki, Toshifumi Noumi, Ryo Saito, Sota Sato, Satoshi Shirai | Summary: The gravitational positivity bound gives quantitative “swampland” constraints on low-energy effective theories inside theories of quantum gravity. We give a comprehensive discussion of this bound for those interested in applications to phenomenological model building. We […]

DualVector: Unsupervised Vector Font Synthesis with Dual-Part Representation

Kavli Affiliate: Matthew Fisher | First 5 Authors: Ying-Tian Liu, Zhifei Zhang, Yuan-Chen Guo, Matthew Fisher, Zhaowen Wang | Summary: Automatic generation of fonts can be an important aid to typeface design. Many current approaches regard glyphs as pixelated images, which present artifacts when scaling and inevitable quality losses after vectorization. On the other hand, […]
