Theory of Spinful Relativistic Superfluids
Dam Thanh Son
We construct an effective field theory description of relativistic superfluids with nonzero angular momentum density. At first order in the derivative expansion, the effective acti…
Short-distance production of three particles with large scattering length
Timothy G. Backert, Sebastian Dietz, Hans-Werner Hammer +2
The short-distance production of multi-particle states in high-energy nuclear reactions provides a unique way to study the low-energy properties of few-body systems. In particular,…
Relativistic Guiding-Center Motion: Action Principle, Kinetic Theory, and Hydrodynamics
Dam Thanh Son, Mikhail Stephanov
We treat the guiding-center dynamics in a varying external Maxwell field using a relativistically covariant action principle which reproduces the known Vandervoort expression for t…
Fate of Multiparticle Resonances: From -Balls to He Droplets
Dam Thanh Son, Mikhail Stephanov, Ho-Ung Yee
We consider a system of nonrelativistic particles which form a near-threshold resonance. Assuming no subset of these particles can form a bound state, the resonance can only de…
Unnuclear physics
Hans-Werner Hammer, Dam Thanh Son
We investigate a nonrelativistic version of Georgi's "unparticle physics." We define the unnucleus as a field in a nonrelativistic conformal field theory. Such a field is character…
