Gate-Tunable Graphene Hall Sensors with High Magnetic Field Sensitivity

Kavli Affiliate: Katja C. Nowack | First 5 Authors: Brian T. Schaefer, Brian T. Schaefer, , , | Summary: Solid-state magnetic field sensors are important to both modern electronics and fundamental materials science. Many types of these sensors maintain high sensitivity only in a limited range of temperature and background magnetic field, but Hall-effect sensors […]

Effect of surface chemistry on incorporation of nanoparticles within calcite single crystals

Kavli Affiliate: Joanna Aizenberg | First 5 Authors: Giulia Magnabosco, Iryna Polishchuk, Francesco Palomba, Enrico Rampazzo, Luca Prodi | Summary: Inclusion of additives into calcite crystals allows one to embed non-native proprieties into the inorganic matrix and obtain new functional materials. Up to now, few parameters have been taken into account to evaluate the efficiency […]

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: , , , , | 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 . Specifically, we consider deep surveys covering […]

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 […]

It’s easy to fool yourself: Case studies on identifying bias and confounding in bio-medical datasets

Kavli Affiliate: Michael Brenner | First 5 Authors: Subhashini Venugopalan, Arunachalam Narayanaswamy, Samuel Yang, Anton Geraschenko, Scott Lipnick | Summary: Confounding variables are a well known source of nuisance in biomedical studies. They present an even greater challenge when we combine them with black-box machine learning techniques that operate on raw data. This work presents […]

Robust fabrication of large-area in- and out-of-plane cross-section samples of layered materials with ultramicrotomy

Kavli Affiliate: Sonia Conesa-Boj | First 5 Authors: M. O. Cichocka, M. O. Cichocka, , , | Summary: Layered materials (LMs) such as graphene or MoS$_2$ have recently attracted a great deal of interest. These materials offer unique functionalities due to their structural anisotropy characterized by weak van der Waals bonds along the out-of-plane axis […]
