Non-Hermitian Generalization of Bloch Sphere in Spacetime Algebra
Chih-Wei Wang
We establish a geometric generalization of the Bloch sphere for two-level quantum systems with non-Hermitian Hamiltonians using the Spacetime Algebra (STA) formulation. By lifting…
The Density Operators of Qubit Systems in the Multiparticle Spacetime Algebra
Chih-Wei Wang
We provide a method to write down the density operator for any pure state of multi-qubit systems in the multiparticle spacetime algebra (MSTA) introduced by Doran, Gull, and Lasenb…
Modular Properties of 3D Higher Spin Theory
Wei Li, Feng-Li Lin, Chih-Wei Wang
In the three-dimensional sl(N) Chern-Simons higher-spin theory, we prove that the conical surplus and the black hole solution are related by the S-transformation of the modulus of…
Split Flows in Bubbled Geometries
Chih-Wei Wang
We propose a procedure to clarify part of the physical sector in the five dimensional bubble geometries based on ideas similar to the split attractor flow conjecture proposed by De…
Plumbing the Abyss: Black Ring Microstates
Iosif Bena, Chih-Wei Wang, Nicholas P. Warner
We construct the first smooth, horizonless ``microstate geometries'' that have the same charges, dipole charges and angular momenta as a BPS black ring whose horizon is macroscopic…
Mergers and Typical Black Hole Microstates
Iosif Bena, Chih-Wei Wang, Nicholas P. Warner
We use mergers of microstates to obtain the first smooth horizonless microstate solutions corresponding to a BPS three-charge black hole with a classically large horizon area. Thes…
