A Simple Model Relating Gauge Factor to Filler Loading in Nanocomposite Strain Sensors
(2021)Conductive nanocomposites are often piezoresistive, displaying significant changes in resistance upon deformation, making them ideal for use as strain and pressure sensors. Such composites typically consist of ductile ... -
Printable G-putty for Frequency and Rate Independent, High Performance Strain Sensors
(2021)While nanocomposite electromechanical sensors are expected to display reasonable conductivity and high sensitivity, little consideration is given to eliminating hysteresis and strain rate/frequency dependence from their ... -
Quantifying the dependence of battery rate performance on electrode thickness
(2020)Simultaneous optimization of capacity and rate performance in battery electrodes would be much simplified by access to a simple equation relating rate performance to electrode thickness. Although a number of equations have ... -
Spontaneous emission from semiconductor nanocrystals in coupled spherical microcavities
(2005)We report on the coherent coupling of whispering gallery modes (WGM) in a photonic molecule formed from two melamine-formaldehyde spherical microcavities coated with a thin shell of light-emitting CdTe nanocrystals (NCs). ... -
Hybrid organic-inorganic spin-on-glass CuCl films for optoelectronic applications
(2009)Cuprous halides are among the most studied inorganic materials for excitonic related linear/non-linear optical processes due to their large excitonic binding energies (~190 and 108 meV for CuCl and CuBr, respectively). In ... -
Temperature dependent photoluminescence of nanocrystalline γ-CuCl hybrid films
(2014)Organic–inorganic hybrid films combine the basic properties of organic and inorganic materials and offer special advantages that enhance optical, thermal and mechanical properties. We have studied the temperature dependent ... -
Surfing Multiple Conformation-Property Landscapes via Machine Learning: Designing Single-Ion Magnetic Anisotropy
(2020)Computational statistical disciplines, such as machine learning, are leading to a paradigm shift in the way we conceive the design of new compounds, offering a way to directly design the best compound for specific applications. ... -
Energy Current Rectification and Mobility Edges
(2019)We investigate how the presence of a single-particle mobility edge in a system can generate strong energy current rectification. Specifically, we study a quadratic bosonic chain subject to a quasiperiodic potential and ... -
Thermodynamic Uncertainty Relations from Exchange Fluctuation Theorems
(2019)Thermodynamic uncertainty relations (TURs) place strict bounds on the fluctuations of thermodynamic quantities in terms of the associated entropy production. In this Letter, we identify the tightest (and saturable) ... -
Multipartite entanglement in the Eigenstate Thermalisation Hypothesis
(2020)We study the quantum Fisher information (QFI) and, thus, the multipartite entanglement structure of thermal pure states in the context of the eigenstate thermalization hypothesis (ETH). In both the canonical ensemble and ... -
Logarithmic growth of local entropy and total correlations in many-body localized dynamics
(2020)The characterizing feature of a many-body localized phase is the existence of an extensive set of quasi-local conserved quantities with an exponentially localized support. This structure endows the system with the signature ... -
Analysis of the conditional mutual information in ballistic and diffusive non-equilibrium steady-states
(2020)The conditional mutual information (CMI) ℐ(A:C|B) quantifies the amount of correlations shared between A and C given B. It therefore functions as a more general quantifier of bipartite correlations in multipartite scenarios, ... -
Eigenstate Thermalisation in a Locally Perturbed Integrable System
(2020)Eigenstate thermalization is widely accepted as the mechanism behind thermalization in generic isolated quantum systems. Using the example of a single magnetic defect embedded in the integrable spin-1/2 XXZ chain, we show ... -
Low-frequency behavior of off-diagonal matrix elements in the integrable XXZ chain and in a locally perturbed quantum-chaotic XXZ chain
(2020)We study the matrix elements of local operators in the eigenstates of the integrable XXZ chain and of the quantum-chaotic model obtained by locally perturbing the XXZ chain with a magnetic impurity. We show that, at ... -
Nonreciprocal quantum transport at junctions of structured leads
(2019)We propose and analyze a mechanism for rectification of spin transport through a small junction between two spin baths or leads. For interacting baths, we show that transport is conditioned on the spacial asymmetry of the ... -
Role of coherence in the nonequilibrium thermodynamics of quantum systems
(2019)Exploiting the relative entropy of coherence, we isolate the coherent contribution in the energetics of a driven nonequilibrium quantum system. We prove that a division of the irreversible work can be made into a coherent ... -
Spin Heat Engine Coupled to a Harmonic-Oscillator Flywheel
(2019)We realize a heat engine using a single-electron spin as a working medium. The spin pertains to the valence electron of a trapped ^{40}Ca^{+} ion, and heat reservoirs are emulated by controlling the spin polarization via ... -
Quantum coherence and ergotropy
(2020)Constraints on work extraction are fundamental to our operational understanding of the thermodynamics of both classical and quantum systems. In the quantum setting, finite-time control operations typically generate coherence ... -
The Role of Quantum Work Statistics in Many-Body Physics
(2018)In this contribution, we aim to illustrate how quantum work statistics can be used as a tool in order to gain insight on the universal features of non-equilibrium many-body systems. Focusing on the two-point measurement ... -
Asymmetry in energy versus spin transport in certain interacting disordered systems
(2019)We study energy transport in disordered XXZ spin-1/2 chains driven to nonequilibrium configurations by thermal reservoirs of different temperatures at the boundaries, using large-scale matrix product simulations. In ...
