Volume as an index of a subalgebra
Samuel Leutheusser, Hong Liu
We propose a new way to understand the volume of certain subregions in the bulk of AdS spacetime by relating it to an algebraic quantity known as the index of inclusion. This index…
Effective field theories of dissipative fluids with one-form symmetries
Shreya Vardhan, Sašo Grozdanov, Samuel Leutheusser +1
A system with a one-form global symmetry at finite temperature can be viewed as a dissipative fluid of string-like objects. In this work, we classify and construct the most general…
Superadditivity in large field theories and performance of quantum tasks
Samuel Leutheusser, Hong Liu
Field theories exhibit dramatic changes in the structure of their operator algebras in the limit where the number of local degrees of freedom () becomes infinite. An important e…
Strong-field magnetohydrodynamics for neutron stars
Shreya Vardhan, Sašo Grozdanov, Samuel Leutheusser +1
We present a formulation of magnetohydrodynamics which can be used to describe the evolution of strong magnetic fields in neutron star interiors. Our approach is based on viewing m…
