The use of molten salts as coolants, fuels, and tritium breeding blankets in the next generation fission fusion nuclear reactors benefits from furthering characterization molecular structure halide salts, paving way to predictive capability chemical thermophysical properties salts.

Molten fluoride salts such as Li 2 BeF 4 (FLiBe) are used in molten salt reactors, fluoride-salt-cooled high-temperature reactors and fusion a fuel solvent, coolant and/or tritium breeding medium. In engineered systems that use salt, solid-state material will be present during melting freezing scenarios, therefore the temperature-dependent properties of solid solid/liquid phase transition merit investigation. To observe behavior state from room temperature to melting, this work neutron X-ray...
An experimental study is made of the initiation and growth explosion in a series azides fulminates. Some organic inorganic which can be melted have been prepared. In solid state impact sensitivity these increased by presence grit particle, provided its melting-point exceeds 500° C. liquid cyanuric triazide initiated adiabatic compression gas bubble, but even apparent absence bubbles molten explosive very sensitive to impact. investigation from point shows that with reaction begin as...
Understanding molten salt chemistry is essential in ongoing research of the nuclear reactor (MSR). In this context, detailed understanding mechanisms underlying selective oxidation metal species, such as Cr, required to guide design effective corrosion mitigation strategies salts. An important starting point for mechanistic knowledge solvation structure and its role controlling speciation. work, we use ab initio molecular dynamics simulations study short-range (on scale nearest-neighbor bond...
Recent work involving virtual excitation of a spin (3/2) baryon resonance is seen to contain two distinct problems. The Feynman propagator for from the Rarita-Schwinger formalism has often been mistaken its on-mass-shell limit. In nonrelativistic direct channel exchange \ensuremath{\Delta} normally included, but with exclusion term intermediate anti-\ensuremath{\Delta}. It shown that both these terms are equal importance in region case nucleon Compton scattering.
Rate constants for the vibrational relaxation of 12C16O(v=1) and 13C18O(v=1) by 4He 3He over an ab initio potential surface have been calculated with a close-coupling, rotational infinite order sudden (VCC-IOS) technique. Improved experimental measurements new deactivation all temperature range 300–80 K carried out laser fluorescence method. These rate existing ones 12C16O 2300–580 are compared theoretical constants. The vary six orders magnitude but calculations reproduce values well....
We present an analytical study of the standard two-party deterministic dense-coding protocol, under which communication perfectly distinguishable messages takes place via a qudit from pair nonmaximally entangled qudits in pure state $|\ensuremath{\psi}⟩$. Our results include following: (i) prove that it is possible for $|\ensuremath{\psi}⟩$ with lower entanglement entropy to support sending greater number than one higher entropy, confirming result suggested numerical analysis Mozes et al....
For one-qubit systems, we present a short, elementary argument characterizing unital quantum operators in terms of their action on Bloch vectors. We then show how our approach generalizes to multiqubit obtaining inequalities that govern when ``diagonal'' superoperator the region is operator. These are n-qubit analog Algoet-Fujiwara conditions. Our work facilitated by an analysis operator-sum decompositions which negative summands allowed.
We report the results of constant-potential molecular dynamics simulations double layer interface between molten 2LiF-BeF2 (FLiBe) and 23LiF-6NaF-21KF (FLiNaK) fluoride mixtures idealized solid electrodes. Employing methods similar to those used in studies chloride layers, we compute structure differential capacitance electric layers as a function applied voltage. The role salt is probed through comparisons FLiBe FLiNaK, which serve models for strong weak associate-forming salts,...
Let N be a (large) positive integer, let b an integer satisfying 1 < that is relatively prime to N, and r the order of modulo N. Finally, QC quantum computer whose input register has size specified in Shor's original description his order-finding algorithm.

We prove when implemented on QC, then P obtaining (nontrivial) exceeds.7 whenever ≥ 211 40, establish that.7736...
We present an exact analytical solution to a one-dimensional model of the susceptible–infected–recovered (SIR) epidemic type, with infection rates dependent on nearest-neighbor occupations. use quantum mechanical approach, transforming master equation via spin operator formulation. calculate exactly time-dependent density infected, recovered and susceptible populations for random initial conditions. Our results compare well those previous work, validating as useful tool additional extended...
The exact energy spectrum is developed for a two temperature kinetic Ising spin chain, and its dual reaction diffusion system with spatially alternating pair annihilation creation rates. Symmetries of the pseudo-Hamiltonian that enable calculation are also used to derive explicit state vectors small sizes, make observations regarding in general case. Physical consequences surprisingly simple form eigenvalues discussed.
