Real-time Scattering in ϕ^4 Theory using Matrix Product States
Bahaa Al Sayegh, Wissam Chemissany
We investigate the critical behavior and real-time scattering dynamics of the interacting quantum field theory in (1+1)-dimensions using uniform matrix product states (uMPS)…
On Infinite Tensor Networks, Complementary Recovery and Type II Factors
Wissam Chemissany, Elliott Gesteau, Alexander Jahn +2
We initiate a study of local operator algebras at the boundary of infinite tensor networks, using the mathematical theory of inductive limits. In particular, we consider tensor net…
Non-isometry, State Dependence and Holography
Stefano Antonini, Vijay Balasubramanian, Ning Bao +2
We establish an equivalence between non-isometry of quantum codes and state-dependence of operator reconstruction, and discuss implications of this equivalence for holographic dual…
Relational Quantum Geometry
Shadi Ali Ahmad, Wissam Chemissany, Marc S. Klinger +1
A common feature of the extended phase space of gauge theory, the crossed product of quantum theory, and quantum reference frames (QRFs) is the adjoining of degrees of freedom foll…
Quantum Reference Frames from Top-Down Crossed Products
Shadi Ali Ahmad, Wissam Chemissany, Marc S. Klinger +1
All physical observations are made relative to a reference frame, which is a system in its own right. If the system of interest admits a group symmetry, the reference frame observi…
Overlapping qubits from non-isometric maps and de Sitter tensor networks
ChunJun Cao, Wissam Chemissany, Alexander Jahn +1
We construct approximately local observables, or "overlapping qubits", using non-isometric maps and show that processes in local effective theories can be spoofed with a quantum sy…
