Triangular Ising antiferromagnet through a fermionic lens, part 2: information-theoretic aspects of zero-temperature states on cylinders
Amir Nourhani, Vincent H. Crespi, Paul E. Lammert
A classical lattice spin model wrapped on a cylinder is profitably viewed as a chain of rings of spins. From that perspective, mutual information between ring configurations plays…
Classical triangular lattice antiferromagnetic Ising model as a free-fermion/superconductor system
Amir Nourhani, Vincent H. Crespi, Paul E. Lammert
We present a treatment of the triangular lattice antiferromagnetic Ising model (TAFIM) based on a small number of elementary ideas common to statistical and solid-state physics. Th…
A Roadmap for Electronic Grade 2-Dimensional Materials
Natalie Briggs, Shruti Subramanian, Zhong Lin +17
Two dimensional (2D) materials continue to hold great promise for future electronics, due to their atomic-scale thicknesses and wide range of tunable properties. However, commercia…
Strong exciton regulation of Raman scattering in monolayer dichalcogenides
Yuanxi Wang, Bruno R. Carvalho, Vincent H. Crespi
The weakly screened electron-hole interactions in an atomically thin semiconductor not only downshift its excitation spectrum from a quasiparticle one, but also redistribute excita…
Full orientation control of epitaxial MoS2 on hBN assisted by substrate defects
Fu Zhang, Yuanxi Wang, Chad Erb +4
Inversion asymmetry in two-dimensional materials grants them fascinating properties such as spin-coupled valley degrees of freedom and piezoelectricity, but at the cost of inversio…
