Besov-Schatten Spaces

Journal of Function Spaces and Applications, 2012
We introduce the Besov-Schatten spaces 𝐵𝑝(ℓ2), a matrix version af analytic Besov space, and we compute the dual of this space showing that it coincides with the matricial Bloch space introduced previously in Popa (2007).

High‐Pressure Modulation of Breathing Kagome Lattice: Cascade of Lifshitz Transitions and Evolution of the Electronic Structure

Advanced Science, EarlyView.
External pressure directly tunes the breathing distortion of the kagome lattice in Fe3Sn2, suppressing it near 15 GPa and reversing it at higher pressures. This structural modulation drives a cascade of Lifshitz transitions, reconstructs the Fermi surface, strengthens electronic correlations and carrier localization, and modifies ultrafast electron ...

Exploring Imaginary Coordinates: Disparity in the Shape of Quantum State Space in Even and Odd Dimensions [PDF]

Quantum
The state of a finite-dimensional quantum system is described by a density matrix that can be decomposed into a real diagonal, a real off-diagonal and and an imaginary off-diagonal part. The latter plays a peculiar role.

Bounded functions in the little Bloch space [PDF]

Pacific Journal of Mathematics, 1990
The author characterizes the bounded functions in the little Bloch space in terms of the measures arising from the canonical factorization theorem. In particular, this answers a question of D. Sarason by characterizing the Blaschke products in the little Bloch space in terms of the distribution of their zeros.

Disorder Driven Anisotropic Nonlinear Hall Effect in the Kagome Metal YbCo6Ge6 at Room Temperature

Advanced Science, EarlyView.
The intrinsic structural disorder and short‐range correlated motifs in the kagome metal YbCo6Ge6 constitute the primary mechanism for a robust and anisotropic nonlinear Hall effect (NLHE). This effect is sustained across a wide temperature range, achieving a nonlinear responsivity of up to ∼4.5 × 10−3 m/V at 70 K, higher than known disordered and ...

Ag Nanowire‐Integrated MoS2/ZnO Heterojunctions for Highly Efficient Photogenerated Charge Transfer

Advanced Electronic Materials, Volume 11, Issue 6, May 2025.
A versatile strategy is reported for fabricating multi‐dimensional heterojunctions with significantly improved charge transfer capability. By integrating Ag nanowires with a MoS2/ZnO heterojunction, a fourfold increase in surface photovoltage is achieved, reaching 200 mV under visible light illumination.

Stabilization of Ultrafast Domain Wall Motion by Edge‐Anisotropy Engineering in Ferrimagnetic Nanowires

Advanced Electronic Materials, EarlyView.
Localized laser annealing transforms distorted, edge‐pinned domain‐wall motion in ferrimagnetic Pt/GdFe nanowires into straight, stable, and ultrafast propagation. Experiments and micromagnetic simulations reveal an optimum anisotropy‐engineering window in which moderate edge softening suppresses pinning, whereas excessive anisotropy reduction or ...

View Order With Arbitrary Center Echoes. [PDF]

Magn Reson Med
ABSTRACT Purpose To provide explicit, vendor‐independent view‐order constructions that enable selection of an arbitrary center echo in multi‐shot imaging, with a focus on RARE and MPRAGE. Methods Vendor‐independent view‐order methods were developed to assign echo and shot indices to a prescribed set of phase encodes, enabling explicit selection of the ...
