Nonadiabatic Theory of Phonon Magnetic Moments in Insulators and Metals
Haoran Chen, Wenqin Chen, Kaijie Yang +2
We develop a nonadiabatic theory of phonon magnetic moments applicable to both insulators and metals. By relating the phonon magnetic moment to the force-velocity response of ions…
Orbital Magnetization of Correlated States in Twisted Bilayer Transition Metal Dichalcogenides
Xiaoyu Liu, Chong Wang, Haoran Chen +3
Recent observations of quantum anomalous Hall effects in moiré systems have revealed the emergence of interaction-driven ferromagnetism with significant orbital contributions. To c…
Anharmonicity and Coulomb pseudopotential effects on superconductivity in YH and YH
Yucheng Ding, Haoran Chen, Junren Shi
Anharmonic effects are widely believed to be the primary cause of the overestimation of superconducting transition temperatures of yttrium hydrides YH and YH in theoretical…
Enhancing superconducting transition temperature of lanthanum superhydride by increasing hydrogen vacancy concentration
Haoran Chen, Hui Wang, Junren Shi
Various clathrate superhydride superconductors have been found to possess hydrogen deficiency in experimental samples, while their impacts on superconductivity are often neglected.…
Emergence of Diffusional Hydrogen Escape in High- Superconducting Calcium Superhydride at Megabar Pressures
Xixi Jia, Haoran Chen, Xiaoqiu Ye +4
High-pressure metal superhydrides have attracted intense scientific interest due to their remarkable superconducting properties. While superconductivity is known to be sensitive to…
Coexistence of Superconductivity and Superionicity in LiMgH
Haoran Chen, Junren Shi
We study superconductivity in the superionic phase of the clathrate hydride LiMgH, where hydrogen ions diffuse among the lattice formed by lithium and magnesium ions. By…
Stochastic path-integral approach for predicting the superconducting temperatures of anharmonic solids
Haoran Chen, Junren Shi
We develop a stochastic path-integral approach for predicting the superconducting transition temperatures of anharmonic solids. By defining generalized Bloch basis, we generalize t…
Non-perturbative approach for calculating the electrical conductivity of a liquid metal
Xiao-Wei Zhang, Haoran Chen, En-Ge Wang +2
We propose a non-perturbative approach to calculate the electrical conductivity of a liquid metal. Our approach is based on the Kubo formula and the theory of electro…
First-principles estimation of the superconducting transition temperature of a metallic hydrogen liquid
Haoran Chen, Xiao-Wei Zhang, Xin-Zheng Li +1
We present a first-principles implementation of the stochastic path-integral approach proposed by Liu et al. [H. Liu, Y. Yuan, D. Liu, X.-Z. Li, and J. Shi, Phys. Rev. Research 2,…
