I investigate some properties of proposed definitions for subsystem/mixed state complexity and uncomplexity. A very strong dependence arises on the density matrix's degeneracy which gives a large…
Multipartite Entanglement and Firewalls
A toy model for black hole decay is constructed which has different entanglement behavior than that assumed by Almheiri-Marolf-Polchinski-Sully (AMPS), and an example which could change the AMPS accounting of quantumEntanglement and perhaps eliminate the need for a firewall is identified.
No firewalls or information problem for black holes entangled with large systems
By introducing a large and inaccessible system entangled with the black hole (representing perhaps a de Sitter stretched horizon or inaccessible part of a landscape) it is shown complementarity can be restored and firewalls can be avoided throughout the black Hole's evolution.

Eternal inflation with arrival terminals
We analyze the cosmological role of terminal vacua in the string theory landscape, and point out that existing work on this topic makes very strong assumptions about the properties of the terminal…
