Renormalization of States and Quasiparticles in Many-body Downfolding
Annabelle Canestraight, Zhen Huang, Vojtech Vlcek
We explore the principles of many-body Hamiltonian complexity reduction via downfolding on an effective low-dimensional representation. We present a unique measure of fidelity betw…
Impact of Subsurface Oxygen on CO2 Charging Energy Changes in Cu Surfaces
Xiaohe Lei, Vojtech Vlcek
Subsurface oxygen in oxide-derived copper catalysts significantly influences CO activation. However, its effect on the molecular charging process, the key to forming the CO$_2^…
Delocalization of Quasiparticle Moiré States in Twisted Bilayer hBN
Arsineh Apelian, Annabelle Canestraight, Songyuan Liu +1
Twisted bilayers host many emergent phenomena in which the electronic excitations (quasiparticles - QPs) are closely intertwined with the local stacking order. By inspecting twiste…
