Ultrafast coherent THz lattice dynamics coupled to spins in a van der Waals antiferromagnetic flake
Fabian Mertens, David Mönkebüscher, Eugenio Coronado +8
A coherent THz optical lattice mode is triggered by femtosecond laser pulses in the antiferromagnetic van der Waals semiconductor FePS. The 380 nm thick exfoliated flake was pl…
Study of charge density waves in suspended 2H-TaS2 and 2H-TaSe2 by nanomechanical resonance
Martin Lee, Makars Šiškins, Samuel Mañas-Valero +3
The charge density wave (CDW) state in van der Waals systems shows interesting scaling phenomena as the number of layers can significantly affect the CDW transition temperature, $T…
Coherent coupling between vortex bound states and magnetic impurities in 2D layered superconductors
Sunghun Park, Vıctor Barrena, Samuel Mañas-Valero +9
Bound states in superconductors are expected to exhibit a spatially resolved electron-hole asymmetry which is the hallmark of their quantum nature. This asymmetry manifests as osci…
van der Waals heterostructures based on atomically-thin superconductors
Carla Boix-Constant, Samuel Mañas-Valero, Rosa Córdoba +1
Van der Waals heterostructures (vdWHs) allow the assembly of high-crystalline two-dimensional (2D) materials in order to explore dimensionality effects in strongly correlated syste…
Controlling the anisotropy of a van der Waals antiferromagnet with light
D. Afanasiev, J. R. Hortensius, M. Matthiesen +9
Magnetic van der Waals materials provide an ideal playground for exploring the fundamentals of low-dimensional magnetism and open new opportunities for ultrathin spin processing de…
Magnetic and electronic phase transitions probed by nanomechanical resonance
Makars Šiškins, Martin Lee, Samuel Mañas-Valero +4
Two-dimensional (2D) materials enable new types of magnetic and electronic phases mediated by their reduced dimensionality like magic-angle induced phase transitions, 2D Ising anti…
