Finite scalar field theory with SU(1,1) spacetime symmetry from near-BPS limits of SYM
Roberto Auzzi, Stefano Baiguera, Lihan Guo +2
In this work, we consider an interacting and matrix-valued scalar quantum field theory that emerges from a near-BPS decoupling limit of super Yang-Mills. The theory…
Probing the bubble interior with entanglement entropy and bulk-cone singularities
Roberto Auzzi, Stefano Baiguera, Lihan Guo +2
In the thin wall approximation, we study a class of asymptotically AdS black holes which contain a spherically symmetric vacuum bubble with a different (positive or negative) cosmo…
Quantum complexity in gravity, quantum field theory, and quantum information science
Stefano Baiguera, Vijay Balasubramanian, Pawel Caputa +4
Quantum complexity quantifies the difficulty of preparing a state or implementing a unitary transformation with limited resources. Applications range from quantum computation to co…
CFT Complexity and Penalty Factors
Stefano Baiguera, Nicolas Chagnet, Shira Chapman +1
Quantum complexity of conformal field theory (CFT) states has recently gained significant attention, both as a diagnostic tool in condensed matter systems and in connection with ho…
Conformal Mapping of Non-Lorentzian Geometries in SU(1,2) Conformal Field Theory
Stefano Baiguera, Troels Harmark, Yang Lei +1
We realize an explicit conformal mapping between the state and operator pictures in a class of (2+1)-dimensional non-Lorentzian field theories with SU(1,2)U(1) conformal sy…
