The unitary Fermi gas at large charge and large N
Simeon Hellerman, Daniil Krichevskiy, Domenico Orlando +3
We study the unitary Fermi gas in a harmonic trapping potential starting from a microscopic theory in the limit of large charge and large number of fermion flavors N. In this regim…
Nonrelativistic CFTs at Large Charge: Casimir Energy and Logarithmic Enhancements
Simeon Hellerman, Domenico Orlando, Vito Pellizzani +2
The unitary Fermi gas, by virtue of its description as a nonrelativistic conformal field theory, has proven an interesting system by which the quantum properties of CFT can be held…
Droplet-Edge Operators in Nonrelativistic Conformal Field Theories
Simeon Hellerman, Ian Swanson
We consider the large-charge expansion of the charged ground state of a Schrodinger-invariant, nonrelativistic conformal field theory in a harmonic trap, in general dimension d. In…
Boundary Operators in Effective String Theory
Simeon Hellerman, Ian Swanson
Various universal features of relativistic rotating strings depend on the organization of allowed local operators on the worldsheet. In this paper, we study the set of Neumann boun…
Effective String Theory Simplified
Simeon Hellerman, Shunsuke Maeda, Jonathan Maltz +1
In this set of notes we simplify the formulation of the Poincare'-invariant effective string theory in D dimensions by adding an intrinsic metric and embedding its dynamics into th…
String Theory of the Regge Intercept
Simeon Hellerman, Ian Swanson
Using the Polchinski-Strominger effective string theory in covariant gauge, we compute the mass of a rotating string in D dimensions with large angular momenta J, in one or two pla…
