Time-reversal symmetry breaking Abelian chiral spin liquid in Mott phases of three-component fermions on the triangular lattice

Frédéric Mila, Karlo Penc, Pierre Marcel Nataf, Miklos Lajko, Carolin Boos

We provide numerical evidence in favor of spontaneous chiral symmetry breaking and the concomitant appearance of an Abelian chiral spin liquid for three-component fermions on the triangular lattice described by an SU(3) symmetric Hubbard model with hopping ...

Unveiling the electronic transformations in the semi-metallic correlated-electron transitional oxide Mo8O23

Marco Grioni, Gianmarco Gatti

Mo8O23 is a low-dimensional chemically robust transition metal oxide coming from a prospective family of functional materials, MoO3-x, ranging from a wide gap insulator (x = 0) to a metal (x = 1). The large number of stoichometric compounds with intermedia ...

Calculated Drude weight and optical gap across the metal-insulator transition in the RVO3 series (R = Sr, Ca, La, Y)

We studied the changes in the optical properties of the RVO3 series (R = Sr, Ca, La, Y) using band structure calculations. These oxides present a transition from a non-magnetic metallic phase in SrVO3-CaVO3, to an antiferromagnetic insulator state in LaVO3 ...

Topological phonons and thermoelectricity in triple-point metals

Quansheng Wu

Recently published discoveries of acoustic- and optical-mode inversion in the phonon spectrum of certain metals became the first realistic example of noninteracting topological bosonic excitations in existing materials. However, the observable physical and ...

A Steep-Slope Transistor Combining Phase-Change and Band-to-Band-Tunneling to Achieve a sub-Unity Body Factor

Mihai Adrian Ionescu, Anna Krammer, Teodor Rosca, Josef Andreas Schuler, Wolfgang Amadeus Vitale, Cem Alper, Arnab Biswas, Emanuele Andrea Casu, Qun Zhao

Steep-slope transistors allow to scale down the supply voltage and the energy per computed bit of information as compared to conventional field-effect transistors (FETs), due to their sub-60 mV/decade subthreshold swing at room temperature. Currently pursu ...

Van der Waals MoS2/VO2 heterostructure junction with tunable rectifier behavior and efficient photoresponse

Olivier Martin, Mihai Adrian Ionescu, Arnaud Magrez, Andreas Schueler, Igor Stolichnov, Anna Krammer, Teodor Rosca, Emanuele Andrea Casu, Chen Yan, Nicolò Oliva

Junctions between n-type semiconductors of different electron affinity show rectification if the junction is abrupt enough. With the advent of 2D materials, we are able to realize thin van der Waals (vdW) heterostructures based on a large diversity of mate ...
