This paper posits that the cosmic digital code as the law of all physical laws contains two mutually exclusive values: attachment space attaching to object and detachment space detaching from object. However, the cosmic physical system could not start with mutually exclusive attachment space and detachment space at the same time in the beginning. The way out of this impasse is that the complete cosmic system consists of both the cosmic physical system and the unphysical cosmic digital code. The unphysical cosmic digital code allows the coexistence of attachment space and detachment space at the same time. The cosmic digital code behaves as gene in organism, and the cosmic physical system behaves as organ. Under different conditions and times, different spaces in the cosmic digital code are activated to generate different spaces in the cosmic physical systems with different physical laws for different universes in the multivese. All universes start from the primitive multiverse, which only has attachment space attaching to 10D string without the four force fields. During the big bang in our universe, detachment space emerged to detach particle from its four force fields. Such detachment, however, cannot be completely and permanently detached, because particle still attaches to its force fields. The result is hybrid space, combining both attachment space and detachment space in coherent state, such as particle and its force fields. Hybrid space is the space for wavefunction whose probability density is proportional to attachment space, and inversely proportional to detachment space. The collapse of wavefunction in decoherent state is the separation of attachment space and detachment space in such way that attachment space attaches to particle, and detachment space separately detaches from all probability density.This paper posits that the cosmic digital code as the law of all physical laws contains two mutually exclusive values: attachment space attaching to object and detachment space detaching from object.

Two- and three-photon detachment of H− by a weak field

Daniel Proulx, Robin Shakeshaft

We describe a method for calculating rates for multiphoton detachment or ionization of a two-electron system by a perturbative field. We have applied the method to ${\mathrm{H}}^{\mathrm{\ensuremath{-}}}$, and we present estimates of two- and three-photon detachment rates. In particular, we explore the $^{1}$ ${\mathit{S}}^{\mathit{e}}$ and $^{1}$ ${\mathit{D}}^{\mathit{e}}$ Feshbach resonances below the n=2 and n=3 excitation thresholds of H; these resonances lie in the ``excess-photon detachment'' regime, where one photon is already sufficient to detach the electron.We describe a method for calculating rates for multiphoton detachment or ionization of a two-electron system by a perturbative field.

Entanglement teleportation between distinct decohered qubits mediated via single and double Majorana wire(s)

Abstract We investigate the decoherence effects from a spin environment on two detached qubits coupled by a single Majorana wire (SMW) and double Majorana wires (DMWs) respectively when teleporting entanglement between the distinct qubits. The role of the composite system parameters on entanglement and entanglement teleportation are examined. Our results shows that strong coupling between the spin environment and the dots modifies the coupling between the qubits and the Majorana fermions (MFs) thus lifting the degenerate zero energy state for the case of the SMW. The SMW is seen to undergo a topological quantum phase transition as seen from the stable asymptotic increase and decrease in its dynamics as the coupling between the qubits and the MFs are varied. We observed that the DMWs are robust against quantum fluctuations of the spin environment with a characteristic cyclic beating phenomenon. This behavior shows that information is mediated via a channel endowed with the anti-ferromagnetic phase and the topological phase that harbors the Majorana zero-energy state. We probe the extent to which the capacitive and pure coupling that defines the DMWs should be tune for entanglement generation between the two sites and thus enhancement of the teleported state. Our description for the Majorana zero modes is in the spin model for spin based quantum applications.Abstract We investigate the decoherence effects from a spin environment on two detached qubits coupled by a single Majorana wire (SMW) and double Majorana wires (DMWs) respectively when teleporting entanglement between the distinct qubits.
