The One‐Dimensional Coulomb Hamiltonian: Properties of Its Birman–Schwinger Operator

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The objective of the present paper is to study in detail the properties of the Birman–Schwinger operator for a self‐adjoint realization of the one‐dimensional Hamiltonian with the Coulomb potential, both when the Hamiltonian is defined only on ℝ+$$ {\mathbb{R}}_{+} $$ and when it is defined on the whole real line.

Fundamental Properties of Heavily Ge‐Doped AlGaN Prepared via Pulsed Sputtering

physica status solidi (b), EarlyView.
This study explores the properties of heavily Ge‐doped AlGaN films prepared via pulsed sputtering deposition. Films with Al content below 34% exhibit higher electron concentrations than Si‐doped counterparts. The maximum carrier concentration reaches 1.8 × 1020 cm−3. Optical bandgaps are enhanced by the Burstein–Moss shift.

Isotropic Lifshitz critical behavior from the functional renormalization group

Nuclear Physics B, 2015
The Lifshitz critical behavior for a single component field theory is studied for the specific isotropic case in the framework of the Functional Renormalization Group.

Two-particle irreducible functional renormalization group schemes---a comparative study

, 2015
We derive functional renormalization group schemes for Fermi systems which are based on the two-particle irreducible approach to the quantum many-body problem.

Nuclear Physics in the Era of Quantum Computing and Quantum Machine Learning

Advanced Quantum Technologies, EarlyView.
The use of QML in the realm of nuclear physics at low energy is almost nonexistent. Three examples of the use of quantum computing and quantum machine in nuclear physics are presented: the determination of the phase/shape in nuclear models, the calculation of the ground state energy, and the identification of particles in nuclear physics experiments ...

Stochastic formulation of the renormalization group: supersymmetric structure and topology of the space of couplings

, 2004
The exact or Wilson renormalization group equations can be formulated as a functional Fokker-Planck equation in the infinite-dimensional configuration space of a field theory, suggesting a stochastic process in the space of couplings.

Cuprate Twistronics for Quantum Hardware

Advanced Quantum Technologies, EarlyView.
This review bridges decades of foundational research with emerging fabrication techniques such as molecular beam epitaxy and cryogenic stacking. By enabling control over electronic correlations and symmetry in twisted cuprate heterostructures, it highlights how cuprate twistronics could open new paths to overcome decoherence and scalability challenges ...

Nanotubes from Transition Metal Dichalcogenides: Recent Progress in the Synthesis, Characterization and Electrooptical Properties

Small, EarlyView.
This review describes recent (mostly last five years) progress in the synthesis, structural characterization, and properties of nanotubes from layered transition metal dichalcogenides, including in‐silico investigations. In the picture, ultra long multiwall nanotubes (up to 0.5 mm) nanotubes reported in Ref.
