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

Posted by klaurent UCSB

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 […]

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

Posted by klaurent UCSB

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 […]

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

Posted by klaurent Stanford

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

Posted by klaurent Tokyo

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 […]

DualVector: Unsupervised Vector Font Synthesis with Dual-Part Representation

Posted by klaurent UCSB

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, […]

Super-Resolution Imaging via Angular Magnification

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Yi Zhou, Dingpeng Liao, Kun Zhang, Zijie Ma, Shikai Wu | Summary: The far-field resolution of optical imaging systems is restricted by the Abbe diffraction limit, a direct result of the wave nature of light. One successful technological approach to circumventing this limit is to reduce the […]

Improved Bounds for Single-Nomination Impartial Selection

Posted by klaurent Berkeley

Kavli Affiliate: Felix Fischer | First 5 Authors: Javier Cembrano, Felix Fischer, Max Klimm, , | Summary: We give new bounds for the single-nomination model of impartial selection, a problem proposed by Holzman and Moulin (Econometrica, 2013). A selection mechanism, which may be randomized, selects one individual from a group of $n$ based on nominations […]

Unconfounded Propensity Estimation for Unbiased Ranking

Posted by klaurent Cornell

Kavli Affiliate: Dan Luo | First 5 Authors: Dan Luo, Lixin Zou, Qingyao Ai, Zhiyu Chen, Chenliang Li | Summary: The goal of unbiased learning to rank (ULTR) is to leverage implicit user feedback for optimizing learning-to-rank systems. Among existing solutions, automatic ULTR algorithms that jointly learn user bias models (i.e., propensity models) with unbiased […]

A non-linear solution to the $S_8$ tension II: Analysis of DES Year 3 cosmic shear

Posted by klaurent Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Calvin Preston, Alexandra Amon, George Efstathiou, , | Summary: Weak galaxy lensing surveys have consistently reported low values of the $S_8$ parameter compared to the $textit{Planck} Lambdarm{CDM}$ cosmology. Amon & Efstathiou (2022) used KiDS-1000 cosmic shear measurements to propose that this tension can be reconciled if the […]
