# Theory of Quantum History Entangled in Time-like Direction

SourceCodeOf_HumanGenome > Theory of Quantum History Entangled in Time-like Direction @ 2008/12/6 11:52
Thinking of each value of t as a name of a degree of freedom, I made a grammar for describing quantum histories entangled in time-like direction.

This grammar first appeared as a post written in Japanese language in http://groups.msn.com/grammar/ on 2005/05/27.
(Links > Japanese > ビンテージ > 文法レベルでの自然 > 中心問題解決案 > 時間の量子化 > 第1件から第12件まで)

After that, it was proposed at JPS 2006 Spring Meeting 27pXA-6 by Yuuichi Uda.

And a new equation corresponding to this grammar instead of the Schrödinger equation first appeared as a post written in Japanese language in http://groups.msn.com/grammar/ on 2005/06/03.
(Links > Japanese > ビンテージ > 文法レベルでの自然 > 中心問題解決案 > 時間の量子化 > 第13件から第27件まで)

After that, it was proposed at APS+JPS 2006 Autumn Meeting by Yuuichi Uda.
He also proposed it at JPS 2007 Spring Meeting 28pSL-11.

Because MSN Group Service was closed on 2009/02, we can not see the above messages now in http://groups.msn.com/grammar/

SourceCodeOf_HumanGenome > New Grammar Version of Schrödinger Equation @ 2011/8/14 14:51
A functional Φ representing an entangled quantum history obeys the new grammar version of Schrödinger equation:

where α is a new physical constant with the dimension of (time)-1 introduced by Yuichi Uda and χ(□-ε) is a function defined as
∀t∈R; [χ(□-ε)](t) = χ(t-ε).

This equation describes the physical law for a particle with mass m in one-dimensional space.
V is a function representing a potential energy.

The reduced form of the new grammar version of Schrödinger equation is analogous to the ordinary Schrödinger equation:

This equation is for a stationary quantum state with energy eigenvalue zero.
mdχ(t)/dt is analogous to qAk(x) and -S[χ] is analogous to qφ(x).
This correspondence is fully understood by writing
qAt[χ] = mdχ(t)/dt, qφ[χ] = -S[χ].

SourceCodeOf_HumanGenome > Unentangled Fundamental Solution @ 2011/8/22 15:32
Yuichi Uda found an unentangled fundamental solution on 2011/04/13.
This solution is written as

when V(x;t) = -[1/(2m)][p(t)]2 - [dp(t)/dt]x.

SourceCodeOf_HumanGenome > Circular Time Regularization @ 2011/8/24 10:54
The circular time was introduced by Yuichi Uda at JPS 2009 Autumn Meeting 13pSH-3 to solve the new grammar version of Schrödinger equation.

When we adopt the circular time, a functional Φ representing a quantum history can be expressed by a function of Fourier coefficients as follows.
Φ[χ] = F(a0[χ],a1[χ],a2[χ],・・・;b1[χ],b2[χ],・・・)
where

Then the functional derivative with respect to χ(t) is written in terms of partial derivatives with respect to the Fourier coefficients.

By using orthogonality of trigonometric functions:

it follows that

On the other hand,

Then the new grammar version of Schrödinger equation is rewritten as follows.

Reducing this equation, it follows that

That is,

SourceCodeOf_HumanGenome > Solution by using circular time in the case V=0 @ 2011/10/12 10:38
If we choose functions f0k0, f1e1,k1, f2e2,k2,・・・ and coefficients c(k0; e1, k1; e2, k2; ・・・) as

then

is a solution of the new grammar version of Schrodinger equation in the case V=0.
The equation for the function f0k is easily solved as follows.

where k is an arbitrary real number.
The equation for the function fne, k is solved as follows which was presented at JPS 2010 Autumn Meeting by Yuichi Uda.
By using Fourier expansion of the function fne, k:

the equation for the function fne, k is rewritten as

To solve this equation, I introduced polar coordinates r and θ in pq-plane as p = r cosθ and q = r sinθ.
Then the equation for the function fne, k reduces to the following expression.

This equation has the following solution.

Because must be continuous, g must be periodic in θ.

where e is an arbitrary real number and k is an arbitrary integer which satisfies:

SourceCodeOf_HumanGenome > Similar problem in the old theories @ 2011/10/26 15:44
The equation for the function fne, k is rewritten as

This is the Schrodinger equation in the old quantum mechanics for a 2-dimensional system with Hamiltonian:

The classical Hamiltonian of this system is

So the classical equations of motion of this system are

To solve this equation is not difficult.
The solution is as follows.

and

Thus the first equation in this message seems not to be pathological.

SourceCodeOf_HumanGenome > Cartoon of the Equation @ 2013/4/3 14:39
I showed a problem of classical mechanics and its solutions as a cartoon of the contents of the reduced form of the new equation at JPS 2013 Spring Meeting.

It originated from the idea on 2011/08/02.

When time is descretized and V = 0, the reduced form of the new grammar version of the Schrodinger equation

is rewitten as follows.

SourceCodeOf_HumanGenome > Probability Formula in New Grammar @ 2013/5/18 13:32
Let Φ be a normalized functional representing a quantum history.
Let the twist remove normalization be used there.

Then the function, representing a transition amplitude of the new grammatical quantum mechanics, corresponding to the Green's function of the old quantum mechanics, is given by the following formula.

Γ(f, t1; g, t2) = ∫Dχ dar(f; t1, t1 + 1/α)Φ[χ]・{[dar(g; t2, t2 + 1/α)]Φ[χ]}*.
This function corresponds to ＜f, t1| g, t2＞ of the old quantum mechanics.

dar(f; a, b) is the stacked Daruma game operator defined as follows.

[dar(f; a, b)]pre Φ[χ] = ∫dx f(x)* Φ[ξ(□,x)]
where ξ is a function such that
ξ(t,x) = χ(t) if t ≦ a or t ≧ b,
ξ(t,x) = x if a < t < b,
it must be smoothened at t = a and t =b.

[dar(f; a, b)] Φ[χ(a,b)] = [dar(f; a, b)]pre Φ[χ]
where
χ(a,b)(t) = χ(t) if t ≦ a,
χ(a,b)(t) = χ(t + (b - a)) if t > a.

The twist remove normalization for a quantum history written in the form:
Φ[χ] = Σj exp[α∫dt φj(χ(t),t)]
is defined by the condition:
(∂/∂ε)∫dx [exp φj(x,t)]* [exp φj(x,t + ε)] |ε = 0.
This condition is satisfied with the function:
φj(x,t) = φ'j(x,t) + (i/h)t∫dx' [exp φ'j(x',t)]* H exp φ'j(x',t)
where exp φ'j is a solution of the old Schrödinger equation and H is the Hamiltonian of it.

However to define the twist remove normalization generally is a remaining problem.
