Hamiltonian Structures for the Generalized Dispersionless KdV Hierarchy
, 1996 We study from a Hamiltonian point of view the generalized dispersionless KdV hierarchy of equations. From the so called dispersionless Lax representation of these equations we obtain three compatible Hamiltonian structures.

Finite-element lattice Hamiltonian matrix elements: Anharmonic oscillators [PDF]
Letters in Mathematical Physics, 1996 The finite-element approach to lattice field theory is both highly accurate (relative errors $\sim 1/N^2$, where $N$ is the number of lattice points) and exactly unitary (in the sense that canonical commutation relations are exactly preserved at the lattice sites).

Advanced Functional Materials, EarlyView.Tin hexathiophosphate memristors leverage intrinsic nanopores together with a guided filament formation strategy to regulate titanium ion motion and switching behavior. The devices support reliable nonvolatile memory and reconfigurable logic‐in‐memory, demonstrating 14 Boolean logic functions in a single cell.

Compression of Hamiltonian matrix: Application to spin-1/2 Heisenberg square lattice
AIP Advances, 2016 We introduce a simple algorithm providing a compressed representation (∈ℝNorbits×Norbits×ℕNorbits) of an irreducible Hamiltonian matrix (number of magnons M constrained, dimension: Nspins!M!(Nspins−M)!>Norbits) of the spin-1/2 Heisenberg antiferromagnet ...

Entanglement spectrum and symmetries in non-Hermitian fermionic non-interacting models
SciPost Physics, 2019 We study the properties of the entanglement spectrum in gapped non-interacting non-Hermitian systems, and its relation to the topological properties of the system Hamiltonian.

The basis of the physical Hilbert space of lattice gauge theories [PDF]
, 1999 Non-linear Fourier analysis on compact groups is used to construct an orthonormal basis of the physical (gauge invariant) Hilbert space of Hamiltonian lattice gauge theories.

Probing Cellular Activity Via Charge‐Sensitive Quantum Nanoprobes
Advanced Materials, EarlyView.A new quantum sensing modality detects shifts in zero‐field splitting caused by charge rearrangement with diamond nanocrystals in response to cellular activity. These electric‐field‐driven effects provide an alternative to temperature‐based interpretations, enabling real‐time, single‐cell readout of inflammation.

A master equation for strongly interacting dipoles
New Journal of Physics, 2018 We consider a pair of dipoles such as Rydberg atoms for which direct electrostatic dipole–dipole interactions may be significantly larger than the coupling to transverse radiation.

A gauge-invariant Hamiltonian analysis for non-Abelian gauge theories in (2+1) dimensions
, 1996 The Hamiltonian formulation for a non-Abelian gauge theory in two spatial dimensions is carried out in terms of a gauge-invariant matrix parametrization of the fields. The Jacobian for the relevant transformation of variables is given in terms of the WZW-
