DOI: 10.1007/jhep07(2018)004
Abstract: A bstractThe DC resistivity of charge density waves weakly-pinned by disorder is controlled by diffusive, incoherent processes rather than slow momentum relaxation. The corresponding incoherent conductivity can be computed in the limit of zero disorder.… read more here.

DOI: 10.1016/j.jallcom.2022.164477
Abstract: We carried out a comprehensive study of the electronic, magnetic, and thermodynamic properties of Ni-doped ZrTe2. High quality Ni0.04ZrTe1.89 single crystals show a possible coexistence of charge density waves (CDW, TCDW ≈ 287 K) with… read more here.

DOI: 10.1021/acs.nanolett.2c04306
Abstract: Layered transition-metal dichalcogenides down to the monolayer (ML) limit provide a fertile platform for exploring charge-density waves (CDWs). Here, we experimentally unveil the richness of the CDW phases in ML-NbTe2 for the first time. Not… read more here.

DOI: 10.1038/s41535-020-0225-5
Abstract: The relationship between charge-density waves (CDWs) and superconductivity is a long-standing debate. Often observed as neighbors in phase diagrams, it is still unclear whether they cooperate, compete, or simply coexist. Using angle-resolved photoemission spectroscopy, we… read more here.

DOI: 10.1063/1.5052722
Abstract: While bulk 1T-TaSe2 is characterized by a commensurate charge density wave (CCDW) state below 473 K, the stability of the CCDW state in a 1T-TaSe2 monolayer, although theoretically predicted, has not been experimentally confirmed so far.… read more here.

Abstract: We study here the spontaneous clustering of a submonolayer of grains under horizontal circular shaking. The clustering of grains occurs when increasing the oscillation amplitude beyond a threshold. The dense area travels in a circular… read more here.

DOI: 10.1093/mnras/stab2652
Abstract: Gravitational coupling between protoplanetary discs and planets embedded in them leads to the emergence of spiral density waves, which evolve into shocks as they propagate through the disc. We explore the performance of a semi-analytical… read more here.
