Mesoscale and Nanoscale Physics
As CMOS technologies face challenges in dimensional and voltage scaling, the
demand for novel logic devices has never been greater, with spin-based devices
offering scaling potential, at the cost of significantly high switching
energies. Al...

Mesoscale and Nanoscale Physics
Quantum Floquet engineering (QFE) seeks to generalize the control of quantum
systems with classical external fields, widely known as Semi-Classical Floquet
engineering (SCFE), to quantum fields. However, to faithfully capture the
physics at...

Neural and Evolutionary Computing
In a seminal paper in 2013, Witt showed that the (1+1) Evolutionary Algorithm
with standard bit mutation needs time (1+o(1))nlnn/p1 to find the optimum
of any linear function, as long as the probability p1 to flip exactly one
bit i...

The evolution of many astrophysical systems is dominated by the interaction
between matter and radiation such as photons or neutrinos. The dynamics can be
described by the evolution equations of radiation hydrodynamics in which

We introduce a formalism for the evaluation of counterfactual queries in the
framework of quantum causal models, generalising Pearl's semantics for
counterfactuals in classical causal models, thus completing the last rung in
the quantum ana...

We study the uniqueness of enhancements of tensor-triangulated categories. To
do so, we provide conditions under which these enhancements interact well with
categorical decompositions. As an application we obtain new results about the

Broadcast and consensus are most fundamental tasks in distributed computing.
These tasks are particularly challenging in dynamic networks where
communication across the network links may be unreliable, e.g., due to mobility
or failures. Ind...
