Scaling down an insect-size microrobot, HAMR-VI into HAMR-Jr

Kavli Affiliate: Robert J. Wood | First 5 Authors: Kaushik Jayaram, Jennifer Shum, Samantha Castellanos, E. Farrell Helbling, Robert J. Wood | Summary: Here we present HAMR-Jr, a SI{22.5}{millimeter}, SI{320}{milligram} quadrupedal microrobot. With eight independently actuated degrees of freedom, HAMR-Jr is, to our knowledge, the most mechanically dexterous legged robot at its scale and is […]

Efficient unitary designs with a system-size independent number of non-Clifford gates

Kavli Affiliate: David Gross | First 5 Authors: Jonas Haferkamp, Felipe Montealegre-Mora, Markus Heinrich, Jens Eisert, David Gross | Summary: Many quantum information protocols require the implementation of random unitaries. Because it takes exponential resources to produce Haar-random unitaries drawn from the full $n$-qubit group, one often resorts to $t$-designs. Unitary $t$-designs mimic the Haar-measure […]

Computational Synthesis of Substrates by Crystal Cleavage

Kavli Affiliate: Kyle Shen | First 5 Authors: Joshua T. Paul, Alice Galdi, Christopher Parzyck, Kyle Shen, Richard G. Hennig | Summary: The discovery of novel substrate materials has been dominated by trial and error, opening the opportunity for a systematic search. To identify stable crystal surfaces, we generate bonding networks for materials from the […]

Spectral analysis on standard locally homogeneous spaces

Kavli Affiliate: Toshiyuki Kobayashi | First 5 Authors: Fanny Kassel, Toshiyuki Kobayashi, , , | Summary: Let $X=G/H$ be a reductive homogeneous space with $H$ noncompact, endowed with a $G$-invariant pseudo-Riemannian structure. Let $L$ be a reductive subgroup of $G$ acting properly on $X$ and $Gamma$ a torsion-free discrete subgroup of $L$. Under the assumption […]

Mitigating the impact of fiber assignment on clustering measurements from deep galaxy redshift surveys

Kavli Affiliate: Naoyuki Tamura | First 5 Authors: Tomomi Sunayama, Masahiro Takada, Martin Reinecke, Ryu Makiya, Takahiro Nishimichi | Summary: We examine the impact of fiber assignment on clustering measurements from fiber-fed spectroscopic galaxy surveys. We identify new effects which were absent in previous, relatively shallow galaxy surveys such as Baryon Oscillation Spectroscopic Survey . […]

Hamiltonian deformations in quantum mechanics, $Tbar T$, and SYK

Kavli Affiliate: David J. Gross | First 5 Authors: David J. Gross, Jorrit Kruthoff, Andrew Rolph, Edgar Shaghoulian, | Summary: Motivated by $Tbar T$, we introduce and study a wide class of solvable deformations of quantum-mechanical theories. These deformations map the Hamiltonian to a function of itself. We solve these theories by computing all finite-temperature […]

Measurement of Beam-Correlated Background Neutrons from the Fermilab Booster Neutrino Beam in ANNIE Phase-I

Kavli Affiliate: Mark Vagins | First 5 Authors: Asheley R. Back, John F. Beacom, Tomaso Boschi, Daniel Carber, Erika Catano-Mur | Summary: The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) aims to make a unique measurement of neutron yield from neutrino-nucleus interactions and to perform R&D for the next generation of water-based neutrino detectors. In this […]

Development of Dual-phase Xenon TPC with a Quartz Chamber for Direct Dark Matter Search

Kavli Affiliate: Masaki Yamashita | First 5 Authors: Kazufumi Sato, Masaki Yamashita, Koichi Ichimura, Yoshitaka Itow, Shingo Kazama | Summary: The idea of a hermetic quartz chamber in a dual-phase xenon time projection chamber (TPC) has the potential to improve the detector sensitivity for direct dark matter searches in the future. A major challenge facing […]
