Variational optimization in the AI era: Computational Graph States and Supervised Wave-function Optimization
Dmitrii Kochkov, Bryan K. Clark
Representing a target quantum state by a compact, efficient variational wave-function is an important approach to the quantum many-body problem. In this approach, the main challeng…
Classical phase diagram of the stuffed honeycomb lattice
Jyotisman Sahoo, Dmitrii Kochkov, Bryan K. Clark +1
We investigate the classical phase diagram of the stuffed honeycomb Heisenberg lattice, which consists of a honeycomb lattice with a superimposed triangular lattice formed by sites…
The mother of all states of the kagome quantum antiferromagnet
Hitesh J. Changlani, Dmitrii Kochkov, Krishna Kumar +2
Frustrated quantum magnets are a central theme in condensed matter physics due to the richness of their phase diagrams. They support a panoply of phases including various ordered s…
