Advanced Functional Materials, EarlyView.This work investigates the Nernst effect in the Kagome magnet ErMn6Sn6 which exhibits both topological and anomalous Nernst effects with the anomalous Nernst coefficient reaching 1.71 µV K⁻¹ at 300 K. This value surpasses that of most canted antiferromagnetic materials, making ErMn6Sn6 a promising candidate for advancing thermoelectric devices based on

Thermodynamic resource theories, non-commutativity and maximum entropy principles
New Journal of Physics, 2017 We discuss some features of thermodynamics in the presence of multiple conserved quantities. We prove a generalisation of Landauer principle illustrating tradeoffs between the erasure costs paid in different ‘currencies’.

Dynamical systems where time is a quantum group and quantum ergodicity [PDF]
arXiv, 2003 We define dynamical systems where time is a quantum group. We give the definition of quantum ergodicity for the introduced dynamical system with noncommutative (or quantum) time, and discuss the examples.

Bayesian quantum noise spectroscopy
New Journal of Physics, 2018 As commonly understood, the noise spectroscopy problem—characterizing the statistical properties of a noise process affecting a quantum system by measuring its response—is mathematically ill-posed, in the sense that no unique noise process leads to a set

Wetting of Surface Grafted Hydrophilic‐b‐Hydrophobic Block Copolymer Brushes
Advanced Functional Materials, EarlyView.The wetting properties of surface grafted diblock copolymer brushes are influenced by the thickness of the hydrophilic bottom block and the hydrophobic top block. The surface adapts in presence of water and the contact angles of the bottom block shine through. Abstract The wetting of diblock copolymer brushes by water is studied.

Experimental graybox quantum system identification and control
npj Quantum InformationUnderstanding and controlling engineered quantum systems is key to developing practical quantum technology. However, given the current technological limitations, such as fabrication imperfections and environmental noise, this is not always possible.

On factorized overlaps: Algebraic Bethe Ansatz, twists, and separation of variables
Nuclear Physics B, 2021 We investigate the exact overlaps between eigenstates of integrable spin chains and a special class of states called “integrable initial/final states”.
