Unruh has commented upon my recent proof that certain predictions of quantum theory are incompatible with the assertion that no influence of any kind acts backward in time in any Lorentz frame. Unruh fails to make a necessary distinction between st...
Inherent gate errors can arise in quantum computation when the actual system Hamiltonian or Hilbert space deviates from the desired one. Two important examples we address are spin-coupled quantum dots in the presence of spin-orbit perturbations to...

The analytic continuation of the Lippmann-Schwinger bras and kets is obtained and characterized. It is shown that the natural mathematical setting for the analytic continuation of the solutions of the Lippmann-Schwinger equation is the rigged Hilbe...

who ranked from 25 to 150, whose association could nominate 2 players. Due to the phase 2 updated by BWF, the following chart is the invitation results
Previously a linkend post: Leveraging PCA to Identify Volatility Regimes for Options Trading I recently implemented Principal Component Analysis (PCA) on volatility metrics across 31 stocks - a ...
Last week was brutal for options sellers. I hope you guys are fine. I was curious which strategy survived the crash from our [Strategy Library](https://blog.deltaray.io/tags/strategies/). Here are t...
I’m interested in hearing from people who traded options or volatility professionally (market making, prop desks, hedge funds, structured products). When a strategy or framework stopped working in ...
In my latest deep dive, I explored how **different volatility lookbacks** affect a volatility-scaled momentum strategy. Instead of just assuming one volatility estimate works best, I tested 1-month (2...
In my journey of discovering financial mathematics, I have been working on a coding project/dashboard with an emphasis on volatility modeling It pulls data from yFinance and uses some basic ARCH mod...
We initiate a study of topological orthoalgebras (TOAs), concentrating on the compact case. Examples of TOAs include topological orthomodular lattices, and also the projection lattice of a Hilbert space. As the latter example illustrates, a lattice...
The hypothesis of empty/full waves considers that a click in a detector is triggered by a property carried by the wave-packet that impinges on that detector. Different authors call this property particle, but according to the terminology of this hy...
