A coherent structure transport model for scrape-off layer turbulence
Zhichen Feng, James Myra, Junyi Cheng +5
Understanding the locality of high-temperature plasma energy deposition on material surfaces in fusion reactors is critical for design. Here, we utilize the Gyrokinetic ElectroMagn…
Global simulations of kinetic-magnetohydrodynamic processes with energetic electrons in tokamak plasmas
Jian Bao, Wenlu Zhang, Ding Li +7
The energetic electrons (EEs) generated through auxiliary heating have been found to destabilize various Alfven eigenmodes (AEs) in recent experiments, which in turn lead to the EE…
MAS: A versatile Landau-fluid eigenvalue code for plasma stability analysis in general geometry
Jian Bao, Wenlu Zhang, Ding Li +8
We have developed a new global eigenvalue code, Multiscale Analysis for plasma Stabilities (MAS), for studying plasma problems with wave toroidal mode number n and frequency omega…
Transport Barrier and Spinning Blob Dynamics in the Tokamak Edge
Junyi Cheng, James Myra, Seung-Hoe Ku +3
In this work, we investigate the dynamics of plasma blobs in the edge of magnetic confinement devices using a full-f gyrokinetic particle-in-cell code with X-point geometry. In sim…
A New Paradigm for Fast and Repetitive Chirping of Alfvén Eigenmodes
Junyi Cheng, Wenlu Zhang, Zhihong Lin +4
A novel 2D nonlinear dynamical paradigm is constructed to interpret the fast and repetitive frequency chirping and amplitude oscillation of Alfvén eigenmodes excited by energetic p…
Which Metric on the Space of Collider Events?
Tianji Cai, Junyi Cheng, Katy Craig +1
Which is the best metric for the space of collider events? Motivated by the success of the Energy Mover's Distance in characterizing collider events, we explore the larger space of…
The Muon Smasher's Guide
Hind Al Ali, Nima Arkani-Hamed, Ian Banta +31
We lay out a comprehensive physics case for a future high-energy muon collider, exploring a range of collision energies (from 1 to 100 TeV) and luminosities. We highlight the advan…
The Linearized Hellinger--Kantorovich Distance
Tianji Cai, Junyi Cheng, Bernhard Schmitzer +1
In this paper we study the local linearization of the Hellinger--Kantorovich distance via its Riemannian structure. We give explicit expressions for the logarithmic and exponential…
Linearized Optimal Transport for Collider Events
Tianji Cai, Junyi Cheng, Katy Craig +1
We introduce an efficient framework for computing the distance between collider events using the tools of Linearized Optimal Transport (LOT). This preserves many of the advantages…
