Hunting for the non-Hermitian exceptional points with fidelity susceptibility
Yu-Chin Tzeng, Chia-Yi Ju, Guang-Yin Chen +1
The fidelity susceptibility has been used to detect quantum phase transitions in the Hermitian quantum many-body systems over a decade, where the fidelity susceptibility density ap…

Simplifying 4d Harmonic Superspace
Dharmesh Jain, Chia-Yi Ju, Warren Siegel
We quantize super Yang-Mills action in harmonic superspace using "Fermi-Feynman" gauge and also develop the background field formalism. This leads to simpler propag…

Non-Hermitian Hamiltonians and no-go theorems in quantum information
Chia-Yi Ju, Adam Miranowicz, Guang-Yin Chen +1
Recently, apparent nonphysical implications of non-Hermitian quantum mechanics (NHQM) have been discussed in the literature. In particular, the apparent violation of the no-signali…
