## Catching a New Force by the Tail

Author(s): Simone Alioli, Marco Farina, Duccio Pappadopulo, and Joshua T. Ruderman

The Large Hadron Collider (LHC) is sensitive to new heavy gauge bosons that produce narrow peaks in the dilepton invariant mass spectrum up to about ${m}_{{Z}^{\prime }}\sim 5\text{\hspace{0.17em}}\text{\hspace{0.17em}}\mathrm{TeV}$ ${Z}^{\prime }\mathrm{s}$ that are too heavy to produce directly can reveal their presence through interference with standard model dilepton production. We show t...

## Native Frames: Disentangling Sequential from Concerted Three-Body Fragmentation

Author(s): Jyoti Rajput, T. Severt, Ben Berry, Bethany Jochim, Peyman Feizollah, Balram Kaderiya, M. Zohrabi, U. Ablikim, Farzaneh Ziaee, Kanaka Raju P., D. Rolles, A. Rudenko, K. D. Carnes, B. D. Esry, and I. Ben-Itzhak

A key question concerning the three-body fragmentation of polyatomic molecules is the distinction of sequential and concerted mechanisms, i.e., the stepwise or simultaneous cleavage of bonds. Using laser-driven fragmentation of OCS into ${\mathrm{O}}^{+}+{\mathrm{C}}^{+}+{\mathrm{S}}^{+}$ and employing coincidence momentum imaging, we demonst...

## New Methods for Testing Lorentz Invariance with Atomic Systems

Author(s): R. Shaniv, R. Ozeri, M. S. Safronova, S. G. Porsev, V. A. Dzuba, V. V. Flambaum, and H. Häffner

We describe a broadly applicable experimental proposal to search for the violation of local Lorentz invariance (LLI) with atomic systems. The new scheme uses dynamic decoupling and can be implemented in current atomic clock experiments, with both single ions and arrays of neutral atoms. Moreover, th...

## Millimeter-Wave Beam Scattering by Field-Aligned Blobs in Simple Magnetized Toroidal Plasmas

Author(s): O. Chellaï, S. Alberti, M. Baquero-Ruiz, I. Furno, T. Goodman, F. Manke, G. Plyushchev, L. Guidi, A. Koehn, O. Maj, E. Poli, K. Hizanidis, L. Figini, and D. Ricci

The first direct experimental measurements of the scattering of a millimeter-wave beam by plasma blobs in a simple magnetized torus are reported. The wavelength of the beam is comparable to the characteristic size of the blob. In situ Langmuir probe measurements show that fluctuations of the electro...

## Spatial Distortion of Vibration Modes via Magnetic Correlation of Impurities

Author(s): F. S. Krasniqi, Y. Zhong, S. W. Epp, L. Foucar, M. Trigo, J. Chen, D. A. Reis, H. L. Wang, J. H. Zhao, H. T. Lemke, D. Zhu, M. Chollet, D. M. Fritz, R. Hartmann, L. Englert, L. Strüder, I. Schlichting, and J. Ullrich

Long wavelength vibrational modes in the ferromagnetic semiconductor ${\mathrm{Ga}}_{0.91}{\mathrm{Mn}}_{0.09}\mathrm{As}$ are investigated using time resolved x-ray diffraction. At room temperature, we measure oscillations in the x-ray diffraction intensity corresponding to coherent vibrational modes with well-defined wavelengths. When ...

## Role of Sink Density in Nonequilibrium Chemical Redistribution in Alloys

Author(s): Enrique Martínez, Oriane Senninger, Alfredo Caro, Frédéric Soisson, Maylise Nastar, and Blas P. Uberuaga

Nonequilibrium chemical redistribution in open systems submitted to external forces, such as particle irradiation, leads to changes in the structural properties of the material, potentially driving the system to failure. Such redistribution is controlled by the complex interplay between the producti...

## Setting Boundaries with Memory: Generation of Topological Boundary States in Floquet-Induced Synthetic Crystals

Author(s): Yuval Baum and Gil Refael

When a $d$-dimensional quantum system is subjected to a periodic drive, it may be treated as a ($d+1$)-dimensional system, where the extra dimension is a synthetic one. This approach, however, affords only a limited level of control of the effective potential along the synthetic direction. In this work,...

## Suppression of Quasiparticle Scattering Signals in Bilayer Graphene Due to Layer Polarization and Destructive Interference

Author(s): Wouter Jolie, Jonathan Lux, Mathias Pörtner, Daniela Dombrowski, Charlotte Herbig, Timo Knispel, Sabina Simon, Thomas Michely, Achim Rosch, and Carsten Busse

We study chemically gated bilayer graphene using scanning tunneling microscopy and spectroscopy complemented by tight-binding calculations. Gating is achieved by intercalating Cs between bilayer graphene and Ir(111), thereby shifting the conduction band minima below the chemical potential. Scatterin...

## Quantum Monte Carlo Simulation of Frustrated Kondo Lattice Models

Author(s): Toshihiro Sato, Fakher F. Assaad, and Tarun Grover

The absence of the negative sign problem in quantum Monte Carlo simulations of spin and fermion systems has different origins. World-line based algorithms for spins require positivity of matrix elements whereas auxiliary field approaches for fermions depend on symmetries such as particle-hole symmet...

## SmartHotel360 - Modernizing Existing Apps with Azure Service Fabric | Visual Studio Toolbox

This is the sixth episode in the SmartHotel360 series, which was used in the keynotes and general sessions at Connect() last November, and is available on GitHub.

In this episode, Brady Gaster talks with Mikkel Hegnhoj from the Azure Service Fabric team about how SmartHotel360 modernized an existing, internal application, by moving it into Azure Service Fabric.

SmartHotel360 is a fictitious smart hospitality company showcasing the future of connected travel:

• The heart of this application is Azure and the code is built using a microservice oriented architecture orchestrated with multiple Docker containers.
• The public website is where hotel guests can book a room, smart conference rooms, and even include their accompanying family travelers and their pets!
• SmartHotel360 offers a fully-native cross-device mobile app for guests and business travelers built with Xamarin. Guests and business travelers can book rooms and smart conference rooms as well as customize room temperature and lighting settings.
• Travelers need quick access to their rooms. We included NFC access from the SmartHotel360 traveler application and we also created a digital door application to check-in and open your room.
• Mixed reality apps provide hotel management the ability to visualize data and review proposed changes to the hotel lobby by using both HoloLens and the latest in immersive headsets.

## Black Hole Entropy from Bondi-Metzner-Sachs Symmetry at the Horizon

Author(s): S. Carlip

Near the horizon, the obvious symmetries of a black hole spacetime—the horizon-preserving diffeomorphisms—are enhanced to a larger symmetry group with a three-dimensional Bondi-Metzner-Sachs algebra. Using dimensional reduction and covariant phase space techniques, I investigate this augmented symme...
