Accurate Measurement of the Gap of Graphene/hBN Moiré Superlattice through Photocurrent Spectroscopy

Kavli Affiliate: Paul L. McEuen | First 5 Authors: Tianyi Han, Jixiang Yang, Qihang Zhang, Lei Wang, Kenji Watanabe | Summary: Monolayer graphene aligned with hexagonal boron nitride (hBN) develops a gap at the charge neutrality point (CNP). This gap has previously been extensively studied by electrical transport through thermal activation measurements. Here, we report […]

An Information Paradox and Its Resolution in de Sitter Holography

Kavli Affiliate: Yasunori Nomura | First 5 Authors: Hao Geng, Yasunori Nomura, Hao-Yu Sun, , | Summary: We formulate a version of the information paradox in de Sitter spacetime and show that it is solved by the emergence of entanglement islands in the context of the DS/dS correspondence; in particular, the entanglement entropy of a […]

Universal scaling for disordered viscoelastic matter near the onset of rigidity

Kavli Affiliate: Itai Cohen | First 5 Authors: Danilo B. Liarte, Stephen J. Thornton, Eric Schwen, Itai Cohen, Debanjan Chowdhury | Summary: The onset of rigidity in interacting liquids, as they undergo a transition to a disordered solid, is associated with a rearrangement of the low-frequency vibrational spectrum. In this letter, we derive scaling forms […]
