Reduced basis surrogates for quantum spin systems based on tensor networks

Within the reduced basis methods approach, an effective low-dimensional subspace of a quantum many-body Hilbert space is constructed in order to investigate, e.g., the ground-state phase diagram. The basis of this subspace is built from solutions of snapsh ...

Unraveling the origin of the peculiar transition in the magnetically ordered phase of theWeyl semimetal Co3Sn2S2

Henrik Moodysson Rønnow, Oleg Yazyev, Ivica Zivkovic, Jian Rui Soh, Ravi Yadav

The recent discovery of topologically nontrivial behavior in Co3Sn2S2 stimulated a notable interest in this itinerant ferromagnet (T-C = 174 K). The exact magnetic state remains ambiguous, with several reports indicating the existence of a second transitio ...

Thermodynamics and dielectric response of BaTiO3 by data-driven modeling

Nicola Marzari, Michele Ceriotti, Giovanni Pizzi, Michele Kotiuga, Max David Veit, Lorenzo Gigli

Modeling ferroelectric materials from first principles is one of the successes of density-functional theory and the driver of much development effort, requiring an accurate description of the electronic processes and the thermodynamic equilibrium that driv ...

Local control theory for superconducting qubits

Ivano Tavernelli, Sara Bonella

In this work, we develop a method to design control pulses for fixed-frequency superconducting qubits coupled via tunable couplers based on local control theory, an approach commonly employed to steer chemical reactions. Local control theory provides an al ...

Magneto-optical properties of single site-controlled InGaAsN quantum wires grown on prepatterned GaAs substrates

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Marco Felici, Romain Carron

The properties of single site-controlled InGaAsN quantum wires (QWRs)-both untreated and irradiated with atomic hydrogen-are probed by micro-magnetophotoluminescence spectroscopy. The strong anisotropy of the diamagnetic shift measured for different orient ...
