Precision bounds for multiple currents in open quantum systems

Autor: Moreira, Saulo V., Radaelli, Marco, Candeloro, Alessandro, Binder, Felix C., Mitchison, Mark T.

Thermodynamic (TUR) and kinetic (KUR) uncertainty relations are fundamental bounds constraining the fluctuations of current observables in classical, non-equilibrium systems. Several works have verified, however, violations of these classical bounds

Symmetry controlled single spin cycloid switching in multiferroic BiFeO3

Autor: Pal, Pratap, Schad, Jonathon L., Vibhakar, Anuradha M., Ojha, Shashank Kumar, Kim, Gi-Yeop, Shenoy, Saurav, Xue, Fei, Rzchowski, Mark S., Bombardi, A., Johnson, Roger D., Choi, Si-Young, Chen, Long-Qing, Ramesh, Ramamoorthy, Radaelli, Paolo G., Eom, Chang-Beom

The single variant spin cycloid and associated antiferromagnetic order in multiferroic BiFeO3 can provide a direct and predictable magnetoelectric coupling to ferroelectric order for deterministic switching, and also a key to fundamental understandin

A tensorial approach to 'altermagnetism'

Autor: Radaelli, Paolo G.

I present a tensorial approach to the description of $\vec{k}/-\vec{k}$-symmetric, time-reversal-odd splitting of electronic bands in magnetic materials, which can be of non-relativistic origin and was recently given the name of `altermagnetism'. I d

Breaking symmetry with light: photo-induced chirality in a non-chiral crystal

Autor: Zeng, Z., Först, M., Fechner, M., Buzzi, M., Amuah, E., Putzke, C., Moll, P. J. W., Prabhakaran, D., Radaelli, P., Cavalleri, A.

Chirality is a pervasive form of symmetry that is intimately connected to the physical properties of solids, as well as the chemical and biological activity of molecular systems. However, its control with light is challenging, because inducing chiral

We present here the preliminary design of the RIZ module, one of the visible spectrographs of the ANDES instrument 1. It is a fiber-fed high-resolution, high-stability spectrograph. Its design follows the guidelines of successful predecessors such as
