The Kitaev model is an exactly solvable S= 1/2 spin model on a 2D honeycomb lattice, in which the spins fractionalize into Majorana fermions and form a topological quantum spin …
BACKGROUND Years ago, Lev Landau taught us how to think about distinct phases of matter through an order parameter that characterizes the symmetry-broken state relative to …
Stacking order can influence the physical properties of two-dimensional van der Waals materials,. Here we applied hydrostatic pressure up to 2 GPa to modify the stacking order in …
The physical properties of two-dimensional van der Waals crystals can be sensitive to interlayer coupling. For two-dimensional magnets,–, theory suggests that interlayer …
In the class of materials called spin liquids,–, a magnetically ordered state cannot be attained even at millikelvin temperatures because of conflicting constraints on each spin; for …
The Kitaev quantum spin liquid (KQSL) is an exotic emergent state of matter exhibiting Majorana fermion and gauge flux excitations. The magnetic insulator α-RuCl3 is thought to …
The exactly solvable Kitaev model on the honeycomb lattice has recently received enormous attention linked to the hope of achieving novel spin-liquid states with …

Geometrical constraints to the electronic degrees of freedom within condensed-matter systems often give rise to topological quantum states of matter such as fractional quantum …
Materials composed of two dimensional layers bonded to one another through weak van der Waals interactions often exhibit strongly anisotropic behaviors and can be cleaved into very …
