Kavli Affiliate: Jie Shan | First 5 Authors: Kaifei Kang, Yichen Qiu, Kenji Watanabe, Takashi Taniguchi, Jie Shan | Summary: Quantum spin Hall (QSH) insulators are a topologically protected phase of matter in two dimensions that can support non-dissipative spin transport. A hallmark of the phase is a pair of helical edge states surrounding an […]
Kavli Affiliate: Jie Shan | First 5 Authors: Kaifei Kang, Bowen Shen, Yichen Qiu, Kenji Watanabe, Takashi Taniguchi | Summary: Quantum spin Hall (QSH) insulators are two-dimensional electronic materials that have a bulk band gap like an ordinary insulator but have topologically protected pairs of edge modes of opposite chiralities. To date, experimental studies have […]

Kavli Affiliate: Johannes Lehmann | First 5 Authors: Christel Baier, Roxane van den Bossche, Sascha Klüppelholz, Johannes Lehmann, Jakob Piribauer | Summary: To improve reliability and the understanding of AI systems, there is increasing interest in the use of formal methods, e.g. model checking. Model checking tools produce a counterexample when a model does not […]
Kavli Affiliate: Darrell G. Schlom | First 5 Authors: Christopher T. Parzyck, Vivek Anil, Yi Wu, Berit H. Goodge, Matthew Roddy | Summary: We present an integrated procedure for the synthesis of infinite-layer nickelates using molecular-beam epitaxy with gas-phase reduction by atomic hydrogen. We first discuss challenges in the growth and characterization of perovskite NdNiO$_3$/SrTiO$_3$, […]
Kavli Affiliate: Jeevak M. Parpia | First 5 Authors: Petri J. Heikkinen, Nathan Eng, Lev V. Levitin, Xavier Rojas, Angadjit Singh | Summary: The symmetry-breaking first-order phase transition between superfluid phases $^3$He-A and $^3$He-B can be triggered extrinsically by ionising radiation or heterogeneous nucleation arising from the details of the sample cell construction. However, the […]

Kavli Affiliate: Jie Shan | First 5 Authors: Phuong X. Nguyen, Raghav Chaturvedi, Liguo Ma, Patrick Knuppel, Kenji Watanabe | Summary: Trions are a three-particle bound state of electrons and holes. Experimental realization of a trion liquid in the degenerate quantum limit would open a wide range of phenomena in quantum many-body physics. However, trions […]
Kavli Affiliate: Grace Xing | First 5 Authors: Shivali Agrawal, Len van Deurzen, Jimy Encomendero, Joseph E. Dill, Hsin Wei | Summary: Ultrawide bandgap heterojunction p-n diodes with polarization-induced AlGaN p-type layers are demonstrated using plasma-assisted molecular beam epitaxy on bulk AlN substrates. Current-voltage characteristics show a turn on voltage of $V_{text{bi}}approx5.5$ V, a minimum […]
