Anomalous Symmetries End at the Boundary

Ryan Thorngren, Yifan Wang

A global symmetry of a quantum field theory is said to have an 't Hooft anomaly if it cannot be promoted to a local symmetry of a gauged theory. In this paper, we show that the ano…

The Half-Full Landau Level

Bertrand I. Halperin

At even-denominator Landau level filling fractions, such as , the ground state, in most cases, has no energy gap, and there is no quantized plateau in the Hall conductance.…

Spatial interference between infectious hotspots: epidemic condensation and optimal windspeed

Johannes Dieplinger, Sauro Succi

We discuss the effects of spatial interference between two infectious hotspots as a function of the mobility of individuals (wind speed) between the two and their relative degree o…

Comparative Analysis of the Solar Wind: Modeling Charge State Distributions in the Heliosphere

Marcus DuPont, Chengcai Shen, Nicholas A. Murphy

Non-equilibrium ionization (NEI) is a key process often times neglected when modeling astrophysical plasmas with thermodynamical timescales much shorter than the timescales for ion…

Metabolic response to point mutations reveals principles of modulation of in vivo enzyme activity and phenotype

Sanchari Bhattacharyyaa, Shimon Bershtein, Bharat V. Adkara +2

The relationship between sequence variation and phenotype is poorly understood. Here we use metabolomic analysis to elucidate the molecular mechanism underlying the filamentous phe…

Chern-Weil Global Symmetries and How Quantum Gravity Avoids Them

Ben Heidenreich, Jacob McNamara, Miguel Montero +3

We draw attention to a class of generalized global symmetries, which we call "Chern-Weil global symmetries," that arise ubiquitously in gauge theories. The Noether currents of thes…

Sondheimer oscillations as a probe of non-ohmic flow in type-II Weyl semimetal WP

Maarten R. van Delft, Yaxian Wang, Carsten Putzke +13

As conductors in electronic applications shrink, microscopic conduction processes lead to strong deviations from Ohm's law. Depending on the length scales of momentum conserving ($…

Using Computer Vision to Automate Hand Detection and Tracking of Surgeon Movements in Videos of Open Surgery

Michael Zhang, Xiaotian Cheng, Daniel Copeland +4

Open, or non-laparoscopic surgery, represents the vast majority of all operating room procedures, but few tools exist to objectively evaluate these techniques at scale. Current eff…

Celestial Amplitudes from UV to IR

Nima Arkani-Hamed, Monica Pate, Ana-Maria Raclariu +1

Celestial amplitudes represent 4D scattering of particles in boost, rather than the usual energy-momentum, eigenstates and hence are sensitive to both UV and IR physics. We show th…
