Near-ultrastrong nonlinear light-matter coupling in superconducting circuits

open access: yesNature Communications
Light-matter interaction between an atom and an electromagnetic resonator is ubiquitous in quantum technologies. Although linear light-matter coupling $$g{\hat{\sigma }}_{x}(\hat{a}+{\hat{a}}^{{{\dagger}} })$$ g σ ̂ x ( a ̂ + a ̂ † ) can reach the ...

Chemical Kinetics of 2‐, 4‐, and 2,4‐Seleno‐Uracils at Low Temperatures: Tautomerizations and Rotamerizations on Inert Matrices

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT In the interstellar medium, chemical reactions proceed under conditions vastly different to those on Earth; these include extremely low temperatures and densities and take place in the gas phase and on water–ice grains. Understanding the energetics and more importantly the kinetics of such reactions is of relevance to the consequences on how ...

On the Role of the Normalization Factors $kappa_n$ and of the Pseudo-Metric ${cal P} neq {cal P}^dag$ in Crypto-Hermitian Quantum Models

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2008
Among ${cal P}$-pseudo-Hermitian Hamiltonians $H ={cal P}^{-1} H^dagger {cal P}$ with real spectra, the ''weaklypseudo-Hermitian" ones (i.e., those employing non-self-adjoint ${cal P} neq {cal P}^dagger$) form a remarkable subfamily. Welist some reasons

Education, Autonomy, and Civic Virtue

open access: yes, 1990
The major cause of our crisis in education is lack of agreement on the purpose of education. We can agree on what that purpose is, Richard Dagger argues. if we define it as the promotion of autonomy and civic virtue.

Some new characterizations of bi-dagger matrices

open access: yes
The concept of the bi-dagger matrix was introduced by Hartwig and Spindelböck [8]. In this paper, we provide some new characterizations of bi-dagger matrices.

Size Matters: Barrier Heights and Widths in the Kinetics Of Tautomerisation and Rotamerisation of Thiotropolone and Its Five‐ and Three‐Membered Cyclic Analogues

open access: yesInternational Journal of Chemical Kinetics, EarlyView.
ABSTRACT Recent experiments by Nunes et al. have demonstrated that unprecedented control of chemical reactions is possible by narrowband infrared vibrational photo‐excitation at low temperatures in inert matrices. The generated higher energy level conformers may then undergo rotamerisation and tautomerisation reactions which provide extremely useful ...

Collagen‐membrane‐covered matrix‐associated chondrocyte implantation improves safety over periosteum‐covered MACI for large knee cartilage defects: A real‐world data analysis in the registry study

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This registry study aimed to evaluate the safety and effectiveness of collagen membrane‐covered matrix‐associated autologous chondrocyte implantation (cMACI) versus periosteum‐covered MACI (pMACI) for large knee cartilage defects (Outerbridge III–IV, ≥4 cm²) in the femorotibial and/or patellofemoral joints with a minimum 2‐year follow ...

Generalized cluster structures on $\mathrm{SL}_n^\dagger$

open access: yes, 2023
We study Poisson varieties $(\mathrm{SL}_n^{\dagger},\pi_{\mathbf{\Gamma}}^{\dagger})$ parameterized by Belavin-Drinfeld triples $\mathbf{\Gamma}$ of type $A_{n-1}$ along with generalized cluster structures $\mathcal{GC}^{\dagger}(\mathbf{\Gamma})$ on ...
