Arrival Time -- Classical Parameter or Quantum Operator?
MohammadJavad Kazemi, MohammadHossein Barati, Ghadir Jafari +2
The question of how to interpret and compute arrival-time distributions in quantum mechanics remains unsettled, reflecting the longstanding tension between treating time as a quant…
Inflation is Not Magic
S. Shajidul Haque, Ghadir Jafari, Bret Underwood
Cosmological perturbations generated during inflation exhibit striking quantum features, including entanglement and high circuit complexity. Yet their observational signatures rema…
Non-Heisenbergian quantum mechanics
MohammadJavad Kazemi, Ghadir Jafari
Relaxing the postulates of an axiomatic theory is a natural way to find more general theories, and historically, the discovery of non-Euclidean geometry is a famous example of this…
Testing loop quantum gravity by quasi-periodic oscillations: rotating blackholes
Jafar Khodagholizadeh, Ghadir Jafari, Alireza Allahyari +1
We investigate a compelling model of a rotating black hole that is deformed by the effects of loop quantum gravity (LQG). We present a simplified metric and explore two distinct ge…
Universal Early-Time Growth in Quantum Circuit Complexity
S. Shajidul Haque, Ghadir Jafari, Bret Underwood
We show that quantum circuit complexity for the unitary time evolution operator of any time-independent Hamiltonian is bounded by linear growth at early times, independent of any c…
