Continuum of Bound States in a Non-Hermitian Model
Qiang Wang, Changyan Zhu, Xu Zheng +3
In a Hermitian system, bound states must have quantized energies, whereas extended states can form a continuum. We demonstrate how this principle fails for non-Hermitian systems, b…
Amplification of quantum signals by the non-Hermitian skin effect
Qiang Wang, Changyan Zhu, You Wang +2
The non-Hermitian skin effect (NHSE) is a phenomenon whereby certain non-Hermitian lattice Hamiltonians, particularly those with nonreciprocal couplings, can host an extensive numb…
Dirac equation for superluminal neutrinos and mass matrix
Chang-Yu Zhu, H. Fan, Shi-Ping Ding
The superluminal is reported in OPERA neutrino experiment (arXiv:1109.4897v2), this result is consistent with previous MINOS experiment about neutrino velocity (Phys. Rev. D 76, 07…
Quantum gravity and mass of gauge field: a four-dimensional unified quantum theory
Chang-Yu Zhu, Heng Fan
We present in detail a four-dimensional unified quantum theory. In this theory, we identify three class of parameters, coordinate-momentum, spin and gauge, as all and as the only f…
A quantum model of dark energy
Chang-Yu Zhu, Heng Fan
We propose a quantum model of dark energy. The proposed candidate for dark energy is gluon field, as is well-known, gluons are the elementary particles. We assume that gluons may n…
A new quantum theory of gravity in the framework of general relativity
Chang-Yu Zhu, Heng Fan
Observed physical phenomena can be described well by quantum mechanics or general relativity. People may try to find an unified fundamental theory which mainly aims to merge gravit…
