Correlated Insulating States and Transport Signature of Superconductivity in Twisted Trilayer Graphene Moiré of Moiré Superlattices
Kan-Ting Tsai, Xi Zhang, Ziyan Zhu +5
Layers of two-dimensional materials stacked with a small twist-angle give rise to beating periodic patterns on a scale much larger than the original lattice, referred to as a moiré…
Effects of Lithium Intercalation in Twisted Bilayer Graphene
Daniel T. Larson, Stephen Carr, Georgios A. Tritsaris +1
We investigate the effects of lithium intercalation in twisted bilayers of graphene, using first-principles electronic structure calculations. To model this system we employ commen…
Efficient Computation of Kubo Conductivity for Incommensurate 2D Heterostructures
Daniel Massatt, Stephen Carr, Mitchell Luskin
Here we introduce a numerical method for computing conductivity via the Kubo Formula for incommensurate 2D bilayer heterostructures using a tight-binding framework. We begin with d…
Angle-Dependent {\it Ab initio} Low-Energy Hamiltonians for a Relaxed Twisted Bilayer Graphene Heterostructure
Shiang Fang, Stephen Carr, Ziyan Zhu +2
We present efficient angle-dependent low-energy Hamiltonians to describe the properties of the twisted bilayer graphene (tBLG) heterostructure, based on {\it ab initio} calculation…
Derivation of Wannier orbitals and minimal-basis tight-binding hamiltonians for twisted bilayer graphene: a first-principles approach
Stephen Carr, Shiang Fang, Hoi Chun Po +2
Twisted bilayer graphene (TBLG) has emerged as an important platform for studying correlated phenomena, including unconventional superconductivity, in two-dimensional systems. The…
Single-Shot Readout Performance of Two Heterojunction-Bipolar-Transistor Amplification Circuits at Millikelvin Temperatures
M. J. Curry, M. Rudolph, T. D. England +12
High-fidelity single-shot readout of spin qubits requires distinguishing states much faster than the T1 time of the spin state. One approach to improving readout fidelity and bandw…
