We explore how the quantum geometric properties of the Bloch wave function, characterized by the Hilbert-Schmidt quantum distance, impact magnetic phases in solid-state systems. To this end, we investigate the spin susce...

HoNiSi3 is an intermetallic compound characterized by two successive antiferromagnetic transitions at TN1 = 6.3 K and TN2 = 10.4 K. Here, its zero-field microscopic magnetic structure is inferred from resonant x-ray magn...

The search strategy or the discovery of new effects for heavy neutrinos often rely on their different decay channels to detectable particles. In particular, in this work we study the decay of a Majorana neutrino with int...

Theoretical matrix elements, for the ground-state to ground-statetwo-neutrino double-beta-decay mode(2 nu }beta -beta of Te128,130isotopes, are calculated within a formalism that describes interactionsbetween neutrons in...

We show how a theory for electrocatalysis developed in our group can be combined with density-functional theory in order to obtain free-energy surfaces for electrochemical reactions. The combined theory is applied to the...

A quantum-mechanical many-particle system may exhibit nonlocal behavior in that measurements performed on one of the particles can affect a second one that is far apart. These so-called entangled states are crucial for t...

Combined electric- and magnetic-field control of magnetization orientation and reversal is studied using anomalous Hall effect in an ultrathin ferromagnetic (Ga,Mn)As/(Ga,Mn)(As,P) bilayer. Its anisotropy results from th...

We have studied the field-dependent ac magnetic susceptibility of single crystals of Dy2Ti2O7 spin ice along the [111] direction in the temperature range 1.8-7 K. Our data reflect the onset of local spin-ice order in the...

The doping of semiconductors with magnetic impurities gives rise not only to a spin-spin interaction between quasifree carriers and magnetic impurities but also to a local spin-independent disorder potential for the carr...

Cell extrusion is an essential mechanism for controlling cell density in epithelial tissues. Another essential element of epithelia is curvature, which is required to achieve complex shapes, like in the lung or intestine...

Effective-medium approaches, such as the coherent potential approximation, are commonly used to describe the rigidity transition of disordered elastic networks. While successful in capturing the universal critical behavi...

We study the Schrödinger equation with 1/r^{3} and attractive 1/r^{2} potentials. Using the quantum defect theory, we obtain analytical solutions for both repulsive and attractive 1/r^{3} interactions. The obtained dis...

In this article we compute the Casimir force between two finite-width mirrors at finite temperature, working in a simplified model in 1+1 dimensions. The mirrors, considered as dissipative media, are modeled by a continu...

We systematically study several classical-quantum correspondence properties of the dissipative modifiedkicked rotator, a paradigmatic ratchet model. We explore the behavior of the asymptotic currents for finite effvalues...

Knowledge of the detailed evolution of the whole charge-state distribution of projectile ions colliding with targets is required in several fields of research such as material science and atomic and nuclear physics but a...

In this work we extend the approach used in [Emanuel Gallo and Osvaldo M. Moreschi, Phys. Rev. D 83, 083007 (2011)PRVDAQ1550-799810.1103/PhysRevD.83.083007] to the study of weak gravitational lensing in a plasma medium. ...

Optimization of computational efficiency and improving predictive stability remain key challenges in reservoir computing (RC) research. Building on the principle of Poincaré recurrence theorem, we propose a dynamic stru...

The influence of the collimating conditions of the incident beam on diffraction patterns produced by grazing scattering of fast atoms off crystal surfaces is studied within a semiquantum approach, called the surface init...

We study the effect of suddenly turning on a long-range interaction in a spinless Fermi gas in two dimensions. The short- to intermediate-time dynamics is described using the method of bosonization of the Fermi surface. ...

Quantum systems with strong long-range interactions are thought to robustly resist thermalization because their energy spectra organize into a discrete number of multiplets. We show that this nonthermal behavior is surpr...

We study the irreversible growth of magnetic thin films under the influence of spatially periodic fields by means of extensive Monte Carlo simulations. We find first-order pseudo-phase transitions that separate a dynamic...

We study time-optimal protocols for controlling quantum systems which show several avoided level crossings in their energy spectrum. The structure of the spectrum allows us to generate a robust guess which is time-optima...

The method of topological renormalization in anti–de Sitter (AdS) gravity consists in adding to the action a topological term which renders it finite, defining at the same time a well-posed variational problem. Here, w...

Synthesizing intense terahertz (THz) waveforms with user-defined electric field profiles represents a pivotal challenge for controlling matter at ultrafast timescales. While relativistic electron beams can serve as a ver...
