Design and Experimental Observation of Valley-Hall Edge States in Diatomic-Graphene-like Elastic Waveguides
Hongfei Zhu, Ting-Wei Liu, Fabio Semperlotti
We report on the design and experimental validation of a two-dimensional phononic elastic waveguide exhibiting topological Valley-Hall edge states. The lattice structure of the wav…
Affine cluster monomials are generalized minors
Dylan Rupel, Salvatore Stella, Harold Williams
We study the realization of acyclic cluster algebras as coordinate rings of Coxeter double Bruhat cells in Kac-Moody groups. We prove that all cluster monomials with g-vector lying…
Magnon and Phonon Dispersion, Lifetime and Thermal Conductivity of Iron from Spin-Lattice Dynamics Simulations
Xufei Wu, Zeyu Liu, Tengfei Luo
In recent years, the fundamental physics of spin-thermal (i.e., magnon-phonon) interaction has attracted significant experimental and theoretical interests given its potential para…
Metadynamics for Training Neural Network Model Chemistries: a Competitive Assessment
John E. Herr, Kun Yao, Ryker McIntyre +2
Neural network (NN) model chemistries (MCs) promise to facilitate the accurate exploration of chemical space and simulation of large reactive systems. One important path to improvi…
Individual Vortex Manipulation and Stick-Slip Motion in Periodic Pinning Arrays
X. Ma, C. J. O. Reichhardt, C. Reichhardt
We numerically examine the manipulation of vortices interacting with a moving trap representing a magnetic force tip translating across a superconducting sample containing a period…
Interdependence Theory of Tissue Failure: Bulk and Boundary Effects
Daniel Suma, Aylin Acun, Pinar Zorlutuna +1
The mortality rate of many complex multicellular organisms increase with age, which suggests that net aging damage is accumulative, despite remodeling processes. But how exactly do…
