COMMUTANTS AND DOUBLE COMMUTANTS OF REFLEXIVE ALGEBRAS

Kyushu Journal of Mathematics, 1996
The author studies the commutant and the double commutant of the algebra \(\text{alg }{\mathcal L}\) of all bounded operators on a Banach space \(X\) leaving invariant each member of a lattice \({\mathcal L}\) of subspaces of \(X\). For example, he proves that when \({\mathcal L}\) is the pentagon subspace lattice, then the only operators commuting ...

Socio‐demographic and geographical patterns in forest and park use: Insights from 33 European countries

People and Nature, EarlyView.
Abstract Access to (urban) nature is vital for people's wellbeing, but this accessibility is not evenly spread across socio‐demographic groups, nor across the European continent. This paper fills a research gap by exploring the use patterns and accessibility of forests and parks across European cities, based on a standardised online survey of 10,462 ...

Fully Quantum Perturbative Description of Correlated Stokes–Anti‐Stokes Scattering

physica status solidi (b), EarlyView.
The generation of Stokes‐anti‐Stokes (SaS) photon pairs with quantum correlations, like entanglement, has been developing recently, but a proper theoretical ground was missing. A fully quantum perturbative theory is provided to describe the four‐wave mixing contribution to the correlated SaS scattering, in which both matter and electromagnetic field ...

Electronic Correlation Effects in the Response of Graphene and MoS2 Monolayers to the Impact of Highly‐Charged Ions

physica status solidi (b), EarlyView.
The response of graphene and MoS2 monolayers to highly‐charged impinging ions is investigated using nonequilibrium Green functions theory. Electronic correlations are found to have a significantly stronger influence on the ultrafast ion‐induced electron dynamics in MoS2 than in graphene.

Unveiling Hidden Features of Strongly Correlated Quantum Systems Through a Complex‐Network Analysis

Advanced Quantum Technologies, EarlyView.
By applying complex network theory, we report a fundamental and previously unobserved phenomenon in the finite‐size Kitaev model: a singular point at which uniform, nonzero entanglement emerges among all fermion pairs, forming a complete entanglement network.

Space‐Efficient Logical Qubit Architecture with a Bus for Magic State Consumption

Advanced Quantum Technologies, EarlyView.
This paper proposes a logical qubit architecture, considering the consumption of magic states. By constructing the patch to the magic state using the repetition code and data qubits using the surface code, the proposed architecture minimizes the number of qubits, referred to as the space cost.
