Photo-induced switching between collective quantum states of matter is a fascinating rising field with exciting opportunities for novel technologies. Presently, very intensively studied examples in this regard are nanometer-thick single crystals of the layered material 1T-TaS2, where picosecond laser pulses can trigger a fully reversible insulator-to-metal transition (IMT). This IMT is believed to be connected to the switching between metastable collective quantum states, but the microscopic… 

Snapshots of a light-induced metastable hidden phase driven by the collapse of charge order

Nonequilibrium hidden states provide a unique window into thermally inaccessible regimes of strong coupling between microscopic degrees of freedom in quantum materials. Understanding the origin of

Photoinduced multistage phase transitions in Ta2NiSe5

By combining transport measurement with ultrashort photoexcitation and coherent phonon spectroscopy, this work reports on photoinduced multistage phase transitions in Ta2NiSe5, finding that nano-sheet samples with the thickness less than the optical penetration depth are required for attaining a complete transition.

It is shown that inter-layer effects play an important role in the charge ordering transition of 1T-TaS2, a layered compound which has a low-temperature insulating phase comprising charge order clusters with 13 unpaired orbitals each.

Preferential out-of-plane conduction and quasi-one-dimensional electronic states in layered 1T-TaS2

Layered transition metal dichalcogenides (TMDs) are commonly classified as quasi-two-dimensional materials, meaning that their electronic structure closely resembles that of an individual layer,

Quantum billiards with correlated electrons confined in triangular transition metal dichalcogenide monolayer nanostructures

This work studies the quantum interference effects of correlated electrons confined in monolayer quantum nanostructures, created by femtosecond laser-induced quench through a first-order polytype structural transition in a layered transition-metal dichalcogenide material.

Intercalation is an effective method to modify physical properties and induce novel electronic states of transition metal dichalcogenide (TMD) materials. However, it is difficult to reveal the



Controlling the metal-to-insulator relaxation of the metastable hidden quantum state in 1T-TaS2

The metastable state relaxation rate may be externally stabilized by substrate strain, thus opening the way to the design of nonvolatile ultrafast high-temperature memory devices based on switching between CDW states with large intrinsic differences in electrical resistance.
