Momentum-space entanglement for interacting fermions at finite density
Ting-Chen Leo Hsu, Michael B. McDermott, Mark Van Raamsdonk
We investigate the entanglement between individual field theory modes in finite-density systems of interacting relativistic and non-relativistic fermions in one spatial dimension.…
Rindler Quantum Gravity
Bartlomiej Czech, Joanna L. Karczmarek, Fernando Nogueira +1
In this note, we explain how asymptotically globally AdS spacetimes can be given an alternate dual description as entangled states of a pair of hyperbolic space CFTs, which are ass…
The Gravity Dual of a Density Matrix
Bartlomiej Czech, Joanna L. Karczmarek, Fernando Nogueira +1
For a state in a quantum field theory on some spacetime, we can associate a density matrix to any subset of a given spacelike slice by tracing out the remaining degrees of freedom.…
