The search for dark matter candidate, ALP, together with CP-odd Higgs boson and tau leptons at TeV

Tetiana Obikhod, Ievgenii Petrenko

The cosmological observations of gravitational lenses, cosmic microwave background, rotation speed of stars in galaxies confirm the existence of about 27% dark matter in the Univer…

Mapping of valley-splitting by conveyor-mode spin-coherent electron shuttling

Mats Volmer, Tom Struck, Arnau Sala +10

In Si/SiGe heterostructures, the low-lying excited valley state seriously limit operability and scalability of electron spin qubits. For characterizing and understanding the local…

Limitations on the maximal level of entanglement of two singlet-triplet qubits in GaAs quantum dots

Igor Bragar, Łukasz Cywiński

We analyze in detail a procedure of entangling of two singlet-triplet (-) qubits operated in a regime when energy associated with the magnetic field gradient, , i…

Observation of a 1/3 Magnetisation Plateau Phase as Evidence for the Kitaev Interaction in a Honeycomb-Lattice Antiferromagnet

Yanyan Shangguan, Song Bao, Zhao-Yang Dong +24

Fractional magnetisation plateaus, in which the magnetisation is pinned at a fraction of its saturated value within a range of external magnetic field, are spectacular macroscopic…

Non-Hermitian gravitational effects on Bose-Einstein condensate

Tie-Fu Zhang, Chengxi Li, Yitong Pei +2

We investigated the impact of Non-Hermitian gravitational potentials on the spatial distribution of Bose-Einstein condensate (BEC) wave functions. Through numerical solutions of th…
