The Euler Number of Bloch States Manifold and the Quantum Phases in Gapped Fermionic Systems

open access: yes, 2013
We propose a topological Euler number to characterize nontrivial topological phases of gapped fermionic systems, which originates from the Gauss-Bonnet theorem on the Riemannian structure of Bloch states established by the real part of the quantum ...

Berry's phase and the anomalous velocity of Bloch wavepackets

open access: yes, 2010
The semiclassical equations of motion for a Bloch electron include an anomalous velocity term analogous to a $k$-space "Lorentz force", with the Berry connection playing the role of a vector potential. By examining the adiabatic evolution of Bloch states

Off Resonant Pumping for Transition from Continuous to Discrete Spectrum and Quantum Revivals in Systems in Coherent States [PDF]

open access: yes, 2000
We show that in parametrically driven systems and, more generally, in systems in coherent states, off-resonant pumping can cause a transition from a continuum energy spectrum of the system to a discrete one, and result in quantum revivals of the initial ...

Weighted Differentiation Composition Operators to Bloch-Type Spaces

open access: yesAbstract and Applied Analysis, 2013
We characterized the boundedness and compactness of weighted differentiation composition operators from BMOA and the Bloch space to Bloch-type spaces. Moreover, we obtain new characterizations of boundedness and compactness of weighted differentiation ...

On ℳ-harmonic Bloch space [PDF]

open access: yesProceedings of the American Mathematical Society, 1995
We show that many of the characterizations of analytic Bloch functions also characterize M \mathcal {M} -harmonic Bloch functions.

The closure of derivative average radial integrable spaces in the Bloch space

open access: yesJournal of Inequalities and Applications
A description of the closure in the Bloch space of the Bloch functions that are in the derivative average radial integrable space is given. As a byproduct, we get some new characterizations for the Bloch space B $\mathcal{B}$ , the little Bloch space B 0

Probing non-Hermitian skin effect and non-Bloch phase transitions

open access: yesPhysical Review Research, 2019
In non-Hermitian crystals showing the non-Hermitian skin effect, ordinary Bloch band theory and Bloch topological invariants fail to correctly predict energy spectra, topological boundary states, and symmetry-breaking phase transitions in systems with ...

Quantifying the Impact of Ocrelizumab on Paramagnetic Rim Lesions in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Paramagnetic rim lesions (PRLs) are a subset of chronic active multiple sclerosis (MS) lesions marked by iron‐laden microglia and macrophages. Ocrelizumab, a monoclonal antibody targeting CD20+ B cells, suppresses acute MS activity, but its effect on PRLs remains unclear. In a longitudinal study of 29 ocrelizumab‐treated patients with at least
