Resonating Valence Bond States with Trimer Motifs
Hyunyong Lee, Yun-tak Oh, Jung Hoon Han +1
The trimer resonating valence bond (tRVB) state consisting of an equal-weight superposition of trimer coverings on a square lattice is proposed. A model Hamiltonian of the Rokhsar-…
Classification of trivial spin-1 tensor network states on a square lattice
Hyunyong Lee, Jung Hoon Han
Classification of possible quantum spin liquid (QSL) states of interacting spin-1/2's in two dimensions has been a fascinating topic of condensed matter for decades, resulting in e…
Chirality-driven Hall Transport Phenomena of Spins
Jung Hoon Han, Hyunyong Lee
Experimental and theoretical aspects of Hall-type transport of spins in magnetic insulators are reviewed, with emphasis on their spin chirality origin. A general formalism for line…
Adiabatic Green's function technique and the transient behavior in time-dependent fermion-boson coupled models
Yun-Tak Oh, Yoichi Higashi, Ching-Kit Chan +1
The Lang-Firsov Hamiltonian, a well-known solvable model of interacting fermion-boson system with sideband features in the fermion spectral weight, is generalized to have the time-…
