We report the observation of sharp electrical resonance of water with width ~2 neV in the low radio frequency range at room temperature. The neV level of the resonant width under room temperature (~25 meV) is consistent with the theory in Wang et al (2020) that predicts a macroscopic long-range coherent quantum mechanical excited states, Majorana fermions, resulting from quantum entanglement of proton hopping at hydrogen bonds.

Comments: 19 Pages. A crucial mistake in plotting BW(c=0.01) has been rectified
We study a Dictionary of Tibetan and English by Alexender Csoma de Koros. We draw the natural logarithm of the number of entries, normalised, starting with a letter vs the natural logarithm of the rank of the letter, normalised. We conclude that the Dictionary can be characterised by BW(c=0.01) i.e. a magnetisation curve for the Bragg-Williams approximation of the Ising model with spin to next spin coupling $epsilon$, in the presence of $gamma$ nearest neighbours, and extenal magnetic field H, obeying $frac{ H}{gamma epsilon}=c=0.01$.

We propose a general variational fermionic many-body wavefunction that generates an effective Hamiltonian in quadratic form which can then be exactly solved. The theory can be constructed within density functional theory framework and a self-consistent scheme is proposed for solving the exact density functional theory. We apply the theory to structurally disordered system and a symmetric and asymmetric Hubbard dimer and corresponding lattice models and the the single fermion excitation spectra show a persistent gap due to the fermionic entanglement induced pairing condensate. For disordered system, density of state at the edge of the gap diverges in the thermodynamic limit, suggesting a topologically ordered phase and a sharp resonance is predicted as the gap is not dependent on the temperature of the system. For the symmetric Hubbard model, the gap for both half filling and doped case suggests quantum phase transition between the AFM and SC is a continuous phase transition.

The author put forward that the change of the electron clouds of the transition metal ions is the electron pairing medium in unconventional superconductors. It is just like the vibration of lattice is the electron pairing medium in conventional superconductors. Calculations with TDDFT method show that the frequency of the change of the electron clouds of the transition metal ions is close to that of the lattice. So, the change of the electron clouds can be excited by free electrons. Results of three copper oxide superconductors show that the higher the frequency, the higher the transition temperature. The difference between the change of the electron clouds and the lattice is also presented. The difference can explain special properties of unconventional superconductors, such as real space paring, pseudo energy gap, d symmetry and unconventional isotopy effect.
