A sharp bound on spacetime distance from quantum entanglement
Zhi-Wei Wang, Arshid Shabir, Mir Faizal +1
Ryu-Takayanagi established how boundary entanglement encodes bulk area. We provide the metric counterpart: boundary mutual information imposes a rigorous lower bound on bulk geodes…
A T-Fold Black Hole in Doubled Type IIB
Mir Faizal, Arshid Shabir
We construct an asymptotically flat T-fold representative of a four-dimensional dyonic black-hole charge orbit in doubled type-IIB theory. Starting from the F1-P-NS5-KKM toroidal s…
Reflection-Positive Construction of a Four-Dimensional SU(N) Yang-Mills Theory with Mass Gap and Confinement
Mir Faizal, Arshid Shabir
In the Euclidean view one must first require that positivity not be violated, and from this modest demand, together with locality, a great deal follows: starting from a reflection-…
A Novel Construction of de Sitter Vacua in Heterotic String Theory
Mir Faizal, Arshid Shabir
We present a concrete string-theoretic mechanism that generates four-dimensional de Sitter vacua from non-geometric R-flux compactifications of heterotic string theory. The constru…
Chern-Simons couplings, modular duality, and anomaly cancellation in abelian F-theory
Mir Faizal, Arshid Shabir
F-theory compactifications with a nontrivial Mordell-Weil group realize abelian gauge symmetry through rational sections, but their consistency is ultimately a statement about the…
Geometric Baryogenesis with Chiral-Time Equivalence
Sameer Ahmad Mir, Arshid Shabir, Swatantra Kumar Tiwari +1
The asymmetry between matter and antimatter demands a cause as simple as it is profound. Here we show that a single geometric principle Chiral-Time Equivalence (CTE)-suffices to ge…
