Quantum Dynamics of Attractive and Repulsive Polarons in a Doped MoSe Monolayer
Di Huang, Kevin Sampson, Yue Ni +11
When mobile impurities are introduced and coupled to a Fermi sea, new quasiparticles known as Fermi polarons are formed. There are two interesting, yet drastically different regime…
Physical Vapor Transport Growth of Antiferromagnetic CrCl Flakes Down to Monolayer Thickness
Jia Wang, Zahra Ahmadi, David Lujan +6
The van der Waals magnets CrX (X = I, Br, and Cl) exhibit highly tunable magnetic properties and are promising candidates for developing novel two-dimensional (2D) magnetic dev…
