Discovery of a hybrid topological quantum state in an elemental solid
Md Shafayat Hossain, Frank Schindler, Rajibul Islam +17
Topology and interactions are foundational concepts in the modern understanding of quantum matter. Their nexus yields three significant research directions: competition between dis…
Transport response of topological hinge modes in -BiBr
Md Shafayat Hossain, Qi Zhang, Zhiwei Wang +19
Electronic topological phases are renowned for their unique properties, where conducting surface states exist on the boundary of an insulating three-dimensional bulk. While the tra…
What's knot to like? Observation of a linked loop quantum state
Ilya Belopolski, Guoqing Chang, Tyler A. Cochran +22
Quantum phases can be classified by topological invariants, which take on discrete values capturing global information about the quantum state. Over the past decades, these invaria…
Room-temperature quantum spin Hall edge state in a higher-order topological insulator BiBr
Nana Shumiya, Md Shafayat Hossain, Jia-Xin Yin +24
Room-temperature realization of macroscopic quantum phenomena is one of the major pursuits in fundamental physics. The quantum spin Hall state, a topological quantum phenomenon tha…
Observation of sixfold degenerate fermions in PdSb
Xiàn Yáng, Tyler A. Cochran, Ramakanta Chapai +16
Three types of fermions have been extensively studied in topological quantum materials: Dirac, Weyl, and Majorana fermions. Beyond the fundamental fermions in high energy physics,…
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…
