Charge-density wave associated with higher-order Fermi-surface nesting in monolayer VS2

Fermi surface nesting and charge-density wave formation in rare-earth tritellurides

The Fermi surface of rare-earth tritellurides sRTe3d is investigated in terms of the nesting-driven chargedensity wave formation using positron annihilation and first-principles linear muffin-tin orbital calculations. Fermi surface nesting is revealed as a strong candidate for driving charge-density wave formation in these compounds. The nesting vector obtained from positron annihilation experi...

Hidden fermi surface nesting and charge density wave instability in low-dimensional metals.

The concept of hidden Fermi surface nesting was introduced to explain the general observation that certain low-dimensional metals with several partially filled bands exhibit charge density wave (CDW) instabilities, although their individual Fermi surfaces do not reveal the observed nesting vectors. This concept was explored by considering the Fermi surfaces of the purple bronze AMo(6)O(17) (A =...

Spin density wave order, topological order, and Fermi surface reconstruction

Persistent order due to transiently enhanced nesting in an electronically excited charge density wave.

Non-equilibrium conditions may lead to novel properties of materials with broken symmetry ground states not accessible in equilibrium as vividly demonstrated by non-linearly driven mid-infrared active phonon excitation. Potential energy surfaces of electronically excited states also allow to direct nuclear motion, but relaxation of the excess energy typically excites fluctuations leading to a r...
