Time-Dependent Tunneling in the Thin-Barrier Limit
Tanmay Vachaspati, Frank Wilczek, Zara Yu
The usual WKB analysis for quantum tunneling applies when the tunneling action is large, as it is for tall, wide potential barriers. In contrast we analyze tunneling when the actio…

Design of ALPHA Phase I: A Plasma Haloscope for 10--20 GHz Post-Inflation Axions
ALPHA Collaboration, Xiran Bai, Rustam Balafendiev +54
The axion is a well-motivated hypothetical particle capable of resolving both the strong CP problem and the dark matter mystery, with recent post-inflationary cosmological simulati…

Detecting a long lived false vacuum with quantum quenches
Gianluca Lagnese, Federica Maria Surace, Sid Morampudi +1
Distinguishing whether a system supports alternate low-energy (locally stable) states -- stable (true vacuum) versus metastable (false vacuum) -- by direct observation can be diffi…
