Quantum state tomography via non-convex Riemannian gradient descent
Ming-Chien Hsu, En-Jui Kuo, Wei-Hsuan Yu +2
The recovery of an unknown density matrix of large size requires huge computational resources. The recent Factored Gradient Descent (FGD) algorithm and its variants achieved state-…
Natural Negative-Refractive-Index Materials
Chih-Yu Chen, Ming-Chien Hsu, C. D. Hu +1
Our calculation shows that negative refractive index (NRI), which was known to exist only in metamaterials in the past, can be found in Dirac semimetals (DSM). Electrons in DSM hav…
Topological theory of inversion-breaking charge-density-wave monolayer 1\textit{T}-TiSe
Ming-Chien Hsu, Bahadur Singh, Chuang-Han Hsu +3
A charge density wave (CDW) of a nonzero ordering vector couple electronic states at and statically, giving rise to a reduced Bril…
Machine learning on the electron-boson mechanism in superconductors
Wan-Ju Li, Ming-Chien Hsu, Shin-Ming Huang
To unravel pairing mechanism of a superconductor from limited, indirect experimental data is always a difficult task. It is common but sometimes dubious to explain by a theoretical…
Topological photocurrent responses from chiral surface Fermi arcs
Guoqing Chang, Jiaxin Yin, Titus Neupert +10
The nonlinear optical responses from topological semimetals are crucial in both understanding the fundamental properties of quantum materials and designing next-generation light-se…
Topologically distinct Weyl-fermion pairs: on the effect of magnetic tunnelling
Ming-Chien Hsu, Hsin Lin, M. Zahid Hasan +1
A Weyl semimetal has Weyl nodes that always come in pairs with opposite chiralities. Notably, different ways of connection between nodes are possible and would lead to distinct top…
Aspects of symmetry and topology in the charge density wave phase of 1T-TiSe2
Shin-Ming Huang, Su-Yang Xu, Bahadur Singh +5
The charge density wave (CDW) in 1T-TiSe2 accompanied by the periodic lattice distortion has a nontrivial symmetry configuration. The symmetry is important as an indication of the…
Photoionization of Xe and Rn from the relativistic random-phase theory
Chen-Kai Qiao, Hsin-Chang Chi, Ming-Chien Hsu +5
Photoionization cross section , asymmetry parameter , and polarization parameters , , of Xe and Rn are calculated in the fully relativistic…
Systematic analysis for triple points in all magnetic symmorphic systems and symmetry-allowed coexistence of Dirac points and triple points
Chi-Ho Cheung, R. C. Xiao, Ming-Chien Hsu +3
Similar to Weyl fermions, a recently discovered topological fermion "triple point" can be generated from the splitting of Dirac fermion while the system has inversion symmetry (IS)…
Inducing 3-component fermions in centrosymmetric system by breaking TRS
Chi-Ho Cheung, R. C. Xiao, Ming-Chien Hsu +3
Recent researches show that by breaking inversion symmetry Dirac fermions can split into new fermions with 3-component. In this article, we demonstrate that Dirac fermions can also…
An Envelope Disrupted by a Quadrupolar Outflow in the Pre-Planetary Nebula IRAS19475+3119
Ming-Chien Hsu, Chin-Fei Lee
IRAS 19475+3119 is a quadrupolar pre-planetary nebula (PPN), with two bipolar lobes, one in the east-west (E-W) direction and one in the southeast-northwest (SE-NW) direction. We h…
Collimated Fast Wind in the Pre-Planetary Nebula CRL 618
Chin-Fei Lee, Ming-Chien Hsu, Raghvendra Sahai
Collimated fast winds (CFWs) have been proposed to operate during the post-AGB evolutionary phase (and even earlier during the late AGB phase), responsible for the shaping of pre-p…
