This is an introductory review of the physics of quantum spin liquid states. Quantum
magnetism is a rapidly evolving field, and recent developments reveal that the ground states …

We investigate the spin-1 2 Heisenberg model on the triangular lattice in the presence of
nearest-neighbor J 1 and next-nearest-neighbor J 2 antiferromagnetic couplings. Motivated …

The fractional quantum Hall effect has been one of the most active areas of research in
quantum condensed matter physics for nearly four decades, serving as a paradigm for …

The fractional quantum Hall effect (FQHE) realized in two-dimensional electron systems
under a magnetic field is one of the most remarkable discoveries in condensed matter …

At strong repulsion, the triangular-lattice Hubbard model is described by s= 1/2 spins with
nearest-neighbor antiferromagnetic Heisenberg interactions and exhibits conventional 120° …

Kalmeyer-Laughlin (KL) chiral spin liquid (CSL) is a type of quantum spin liquid without time-
reversal symmetry, and it is considered as the parent state of an exotic type of …

The search for quantum spin liquids in frustrated quantum magnets recently has enjoyed a
surge of interest, with various candidate materials under intense scrutiny. However, an …

We investigate the J 1-J 2 Heisenberg model on the triangular lattice with an additional
scalar chirality term and show that a chiral spin liquid is stabilized in a sizable region of the …

Traditional computational methods for studying quantum many-body systems are “forward
methods,” which take quantum models, ie, Hamiltonians, as input and produce ground …

Abelian and non-Abelian topological phases exhibiting protected chiral edge modes are
ubiquitous in the realm of the fractional quantum Hall (FQH) effect. Here, we investigate a …
