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 […]

Correlation-Driven Electron-Hole Asymmetry in Graphene Field Effect Devices

Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Nicholas Dale, Ryo Mori, M. Iqbal Bakti Utama, Jonathan D. Denlinger, Conrad Stansbury | Summary: Electron-hole asymmetry is a fundamental property in solids that can determine the nature of quantum phase transitions and the regime of operation for devices. The observation of electron-hole asymmetry in graphene and […]

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 […]

Scaling of dynamical susceptibility at the onset of rigidity for disordered viscoelastic matter

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 dramatic rearrangement of the low-frequency vibrational spectrum. In this letter, we derive scaling […]

Four-Spin Terms and the Origin of the Chiral Spin Liquid in Mott Insulators on the Triangular Lattice

Kavli Affiliate: Joel E. Moore | First 5 Authors: Tessa Cookmeyer, Johannes Motruk, Joel E. Moore, , | Summary: At strong repulsion, the triangular-lattice Hubbard model is described by $s=1/2$ spins with nearest-neighbor antiferromagnetic Heisenberg interactions and exhibits conventional 120$^circ$ order. Using the infinite density matrix renormalization group and exact diagonalization, we study the effect […]
