Unitary time-reversal on non-orientable spacetimes
Ovidiu Racorean
Time reversal symmetry occupies a distinctive role in quantum mechanics, fundamentally requiring an anti-unitary operator to ensure a physically consistent representation. As such,…
The non-orientable spacetime of the eternal black hole
Ovidiu Racorean
We derive the metric of the BTZ black hole for the special case of interchanging the characteristics of space and time coordinates. We maximally extend the geometry of this interio…
Eternal black holes and temporal quantum correlations
Ovidiu Racorean
Recent works suggest that quantum theory may support a unification of the notions of space and time, thus treating the spatial and temporal quantum correlations equally. Specifical…
The Born rule in a timeless universe
Ovidiu Racorean
In canonical quantization of gravity the wave function of the universe is CPT invariant. Thus, if the quantum state of the universe contains a particular history, than it must cont…
Quantum entanglement and the non-orientability of spacetime
Ovidiu Racorean
We argue, in the context of Ads/CFT correspondence, that the degree of entanglement on the CFTs side determines the orientation of space and time on the dual global spacetime. That…
AdS/CFT correspondence: the fountain of quantum youth
Ovidiu Racorean
We argue, in the context of AdS/CFT correspondence, that the structure of the geometry dual to two entangled CFTs is a time non-orientable spacetime. Further, we elevate this argum…
Quantum entanglement, two-sided spacetimes and the thermodynamic arrow of time
Ovidiu Racorean
We investigate the emergence of thermodynamic arrow of time in the context of AdS/CFT correspondence. We show that, on the CFT side, if the two copies of the field theory are not i…
Quantum gates implementation by X-ray single-photons around rotating black holes
Ovidiu Racorean
The curvature and twisting of spacetime rotate the angle of polarization and imprint orbital angular momentum to photons emitted by the accretion disk near rotating black holes. Co…
Creation of single-photon entangled states around rotating black holes
Ovidiu Racorean
Recently, numerical simulations showed that X-ray photons emitted by accretion disks acquire rotation of polarization angle and orbital angular momentum due to strong gravitational…
Quantum Gates and Quantum Circuits of Stock Portfolio
Ovidiu Racorean
In quantum computation, series of quantum gates have to be arranged in a predefined sequence that led to a quantum circuit in order to solve a particular problem. What if the seque…
Decoding Stock Market Behavior with the Topological Quantum Computer
Ovidiu Racorean
A surprising image of the stock market arises if the price time series of all Dow Jones Industrial Average stock components are represented in one chart at once. The chart evolves…
Braided and Knotted Stocks in the Stock Market: Anticipating the flash crashes
Ovidiu Racorean
A simple and elegant arrangement of stock components of a portfolio (market index-DJIA) in a recent paper [1], has led to the construction of crossing of stocks diagram. The crossi…
Crossing Stocks and the Positive Grassmannian I: The Geometry behind Stock Market
Ovidiu Racorean
It seems to be very unlikely that all relevant information in the stock market could be fully encoded in a geometrical shape. Still,the present paper will reveal the geometry behin…
Quantum Tunneling of Stock Price in Range Bound Market Conditions
Ovidiu Racorean
Applications of Quantum Tunneling effect have long gone beyond the traditional physical meaning. Initially created by Gamow to explain α-decay of nuclear particles, along the time,…
Correct usage of transmission coefficient for timing the market
Ovidiu Racorean
Traders and investors involved in an option contract having the underlying stock in range bound are likely to lose their initial investment. Timing in buying an option contract is…
Are Financial Markets an aspect of Quantum World?
Ovidiu Racorean
Writing the article-Time independent pricing of options in range bound markets; the question in the title came naturally to my mind. It is stated, in the above article, that in cer…
Time-independent pricing of options in range bound markets
Ovidiu Racorean
Assuming that price of the underlying stock is moving in range bound, the Black-Scholes formula for options pricing supports a separation of variables. The resulting time-independe…
