Quantum free energy differences from non-equilibrium path integrals: I. Methods and numerical application

open access: yes, 2008
The imaginary-time path integral representation of the canonical partition function of a quantum system and non-equilibrium work fluctuation relations are combined to yield methods for computing free energy differences in quantum systems using non ...

Eigenvector continuation with subspace learning

open access: yes, 2018
A common challenge faced in quantum physics is finding the extremal eigenvalues and eigenvectors of a Hamiltonian matrix in a vector space so large that linear algebra operations on general vectors are not possible.

A Graph Theory Approach for Regional Controllability of Boolean Cellular Automata

open access: yes, 2019
Controllability is one of the central concepts of modern control theory that allows a good understanding of a system's behaviour. It consists in constraining a system to reach the desired state from an initial state within a given time interval. When the

Subharmonic solutions for non-autonomous second-order sublinear Hamiltonian systems with p-Laplacian

open access: yesElectronic Journal of Differential Equations, 2011
In this article, we study the existence of subharmonic solutions to the non-autonomous second-order sublinear Hamiltonian systems with p-Laplacian.

High-Resolution Nanoscale Solid-State Nuclear Magnetic Resonance Spectroscopy

open access: yesPhysical Review X, 2018
We present a new method for high-resolution nanoscale magnetic resonance imaging (nano-MRI) that combines the high spin sensitivity of nanowire-based magnetic resonance detection with high-spectral-resolution nuclear magnetic resonance (NMR) spectroscopy.

The singular Hartree equation in fractional perturbed Sobolev spaces

open access: yes, 2018
We establish the local and global theory for the Cauchy problem of the singular Hartree equation in three dimensions, that is, the modification of the non-linear Schr\"odinger equation with Hartree non-linearity, where the linear part is now given by the

Distributed Coordinated Control of Offshore Doubly Fed Wind Turbine Groups Based on the Hamiltonian Energy Method

open access: yes, 2017
To support doubly fed wind turbine (DFWT) groups in offshore wind farms, this paper proposes a distributed coordinated control based on the Hamiltonian energy theory.
