Quantum mechanical calculations reveal the hidden states of enzyme active sites（图）
enzyme active sites Quantum mechanical
2014/12/1
Enzymes carry out fundamental biological processes such as photosynthesis, nitrogen fixation and respiration, with the help of clusters of metal atoms as “active” sites. But scientists lack basic info...
A quantum mechanical model for the relationship between stock price and stock ownership
quantum mechanical model relationship between stock price stock ownership
2012/9/14
The trade of a fixed stock can be regarded as the basic process that measures its momentary price. The stock price is exactly known only at the time of sale when the stock is between traders, that is,...
Finite quantum mechanical model for the stock market
quantum mechanical model stock market
2012/9/14
The price of a given stock is exactly known only at the time of sale when the stock is between the traders. If we know the price (owner) then we have no information on the owner (price). A more genera...
Unitary representations of the Galilean line group: Quantum mechanical principle of equivalence
Unitary representations the Galilean line group Quantum mechanical principle of equivalence
2011/9/5
Abstract: We present a formalism of Galilean quantum mechanics in non-inertial reference frames and discuss its implications for the equivalence principle. This extension of quantum mechanics rests on...
Accurate quantum-mechanical rate constants for a linear response Azzouz-Borgis proton transfer model employing the multilayer multiconfiguration time-dependent Hartree approach
quantum-mechanical linear response Azzouz-Borgia proton transfer model time-dependent Hartree approach
2014/5/28
The multilayer multiconfiguration time-dependent Hartree (ML-MCTDH) method is applied to simulate the quantum dynamics and thermal rate constant of the Azzouz-Borgis model of proton transfer in a pola...
Quantum mechanical potentials exactly solvable in terms of higher hypergeometric functions. I: The third-order case
Quantum mechanical higher hypergeometric third-order
2011/7/25
Abstract: We present a new six-parameter family of potentials whose solutions are expressed in terms of the hypergeometric functions 3F2, 2F2 and 1F2. Both the scattering data and the bound states of ...
Suppression of the quantum-mechanical collapse by repulsive interactions in a quantum gas
Quantum Gases (cond-mat.quant-gas) Pattern Formation and Solitons (nlin.PS)
2010/11/11
The quantum-mechanical collapse (alias fall onto the center of particles attracted by potential -1/r^2), or "quantum anomaly", is a well-known issue in the quantum theory. We demonstrate that the mean...
Quantum Mechanical Simulation of Electronic Transport in Nanostructured Devices by Efficient Self-consistent Pseudopotential Calculation
Quantum Mechanical Simulation of Electronic Transport Nanostructured Devices
2010/11/17
We present a new empirical pseudopotential (EPM) calculation approach to simulate the million
atom nanostructured semiconductor devices under potential bias using the periodic boundary con-
ditions....
Quantum mechanical formalism for biological evolution
Quantum mechanical formalism biological evolution
2010/11/18
We study the evolution of sexual and asexual populations in general fitness landscapes. We
find deep relations between the mathematics of biological evolution and the formalism of quantum mechanics.
On the Quantum Mechanical State of the $\Delta^{++}$ baryon
the Quantum Mechanical State Physics
2010/11/16
The $\Delta^{++}$ and the $\Omega^-$ baryons have been used as the original reason for the construction of the Quantum Chromodynamics theory of Strong Interactions. The present analysis relies on the...

Probabilistic Inequalities Upper Probabilities Quantum Mechanical Entanglement
2010/11/5
In this paper we analyze the existence of joint probabilities for the Bell-type and GHZ entangled states. We then propose the usage of nonmonotonic upper probabilities as a tool to derive consistent j...
