q-Measurement Scheme set in Quantum Photonic Frameworks: Linking Abstract Space and Lab Spaces

Beginning in abstract space and dislodging the representational form paves a way to formulate a version of a quantum physical measurement scheme. With materiality playing sustainment roles with respect to q-states, these latter control system response towards external probes. Sustainment concerns all possible q-states. The particle character usually assigned to eigenstates and eigenvalues dies out, while energy gaps relate to possible energy quanta exchanges; the occupancy concept no longer required. Abstract and laboratory spaces are incommensurate, linking them leads to a possible physical q-measurement theory. Connectors (links) are referred to as gangplanks and/or gangways, they perform in frontiers arbitrating quantum to classical regions. Inertial frames facilitate linking q-state domains via projection to wave function space. A physical quantum measurement theory obtains grounded on these elements including quantum information concepts.

Quantum Matter-Photonics Framework: Analyses of Chemical Conversion Processes

A quantum Matter-Photonics framework is adapted to help scrutinize chemical reaction mechanisms and used to explore a process mapped from chemical tree topological model. The chemical concept of bond knitting/breaking is reformulated via partitioned base sets leading to an abstract and general quantum presentation. Pivotal roles are assigned to entanglement, coherence,de-coherence and Feshbach resonance quantum states that permit apprehend gating states in conversion processes. A view from above in the state energy eigenvalue ladder, belonging to full system spectra complement the standard view from ground state. A full quantum physical view supporting chemical change obtains.

Quantum Entanglement and Decoherence: Beyond Particle Models. A Farewell to Quantum Mechanics's Weirdness

Combining abstract to laboratory projected quantum states a general analysis of headline quantum phenomena is presented. Standard representation mode is replaced; instead quantum states sustained by elementary material constituents occupy its place. Renouncing to assign leading roles to language originated in classical physics when describing genuine quantum processes, together with sustainment concept most, if not all weirdness associated to Quantum Mechanics vanishes.

Quantum physical states for describing photonic assisted chemical change: I. Torsional phenomenon at femtosecond time scale

Femtosecond torsional relaxation processes experimentally detected and recently reported by Clark et al. (Nature Phys. 8,225 (2012)) are theoretically dissected with a Hilbert/Fock quantum physical (QP) framework incorporating entanglement of photon/matter base states overcoming standard semi-classic vibrational descriptions. The quantum analysis of a generic Z/E (cis/trans) isomerization in abstract QP terms shed light to fundamental roles played by photonic spin and excited electronic singlet coupled to triplet states. It is shown that one photon activation cannot elicit femtosecond phenomenon, while a two-photon pulse would do. Estimated time scales for the two-photon case indicate the process to lie between a slower than electronic Franck-Condon-like transition yet faster than (semi-classic) vibration relaxation ones.
