A theory of deconfined pseudo-criticality
Ruochen Ma, Chong Wang
It has been proposed that the deconfined criticality in -- the quantum phase transition between a Neel anti-ferromagnet and a valence-bond-solid (VBS) -- may actually be p…
Isotope effect in superconducting lanthanum hydride under high compression
Artur P. Durajski, Radoslaw Szczesniak, Yinwei Li +2
Recently, the discovery of room-temperature superconductivity (SC) was experimentally realized in the fcc phase of LaH under megabar pressure. Specifically, the isotope effe…
Two-dimensional topological semimetal states in monolayers CuGe, FeGe, and FeSn
Liangliang Liu, Chongze Wang, Jiangxu Li +3
Recent experimental realizations of the topological semimetal states in several monolayer systems are very attractive because of their exotic quantum phenomena and technological ap…
Multiband Nature of the Room-Temperature Superconductivity in Compressed LaH
Chongze Wang, Seho Yi, Jun-Hyung Cho
Recently, the discovery of room-temperature superconductivity (SC) was experimentally realized in the fcc phase of LaH under megabar pressures. This SC of compressed LaH$_{1…
Electric polarization as a nonquantized topological response and boundary Luttinger theorem
Xue-Yang Song, Yin-Chen He, Ashvin Vishwanath +1
We develop a nonperturbative approach to the bulk polarization of crystalline electric insulators in dimensions. Formally, we define polarization via the response to backg…
Crystallographic splitting theorem for band representations and fragile topological photonic crystals
A. Alexandradinata, J. Höller, Chong Wang +2
The fundamental building blocks in band theory are band representations (BRs): bands whose infinitely-numbered Wannier functions are generated (by action of a space group) from a f…
Pressure dependence of the superconducting transition temperature of compressed LaH
Chongze Wang, Seho Yi, Jun-Hyung Cho
Two recent experiments [M. Somayazulu ., Phys. Rev. Lett. , 027001 (2019) and A. P. Drozdov ., Nature , 528 (2019)] reported the discovery o…
Fractional Quantum Hall Effect in Weyl Semimetals
Chong Wang, L. Gioia, A. A. Burkov
Weyl semimetal may be thought of as a gapless topological phase protected by the chiral anomaly, where the symmetries involved in the anomaly are the charge conservation and…
Dirac Fermions in Antiferromagnetic FeSn Kagome Lattices with Combined Space Inversion and Time Reversal Symmetry
Zhiyong Lin, Chongze Wang, Pengdong Wang +14
Symmetry principles play a critical role in formulating the fundamental laws of nature, with a large number of symmetry-protected topological states identified in recent studies of…
Hidden Weyl Fermions in Paramagnetic Electride YC
Liangliang Liu, Chongze Wang, Seho Yi +3
Recent experimental observations of Weyl fermions in materials opens a new frontier of condensed matter physics. Based on first-principles calculations, we here discover Weyl fermi…
