From real materials to model Hamiltonians with density matrix downfolding
Huihuo Zheng, Hitesh J. Changlani, Kiel T. Williams +2
Due to advances in computer hardware and new algorithms, it is now possible to perform highly accurate many-body simulations of realistic materials with all their intrinsic complic…
Continuum of quantum fluctuations in a three-dimensional Heisenberg magnet
K. W. Plumb, Hitesh J. Changlani, A. Scheie +7
Conventional crystalline magnets are characterized by symmetry breaking and normal modes of excitation called magnons with quantized angular momentum . Neutron scattering co…
Quantum versus classical effects at zero and finite temperature in the quantum pyrochlore YbTiO
Hitesh J. Changlani
We study the finite temperature properties of the candidate quantum spin ice material YbTiO within the framework of an anisotropic nearest-neighbor spin model on…
Quantum spin liquid with 7 elementary particles
Haoyu Wang, Hitesh J. Changlani, Yuan Wan +1
We present an exactly solvable model of a quantum spin liquid with Abelian anyons in d=2 spatial dimensions. With spins 1/2 on a triangular lattice and six-body interactions, our m…
Reentrant Phase Diagram of in Magnetic Field
A. Scheie, J. Kindervater, S. Säubert +9
We present a magnetic phase diagram of rare-earth pyrochlore in a magnetic field. Using heat capacity, magnetization, and neutron scatterin…
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…
