Floquet prethermalization of Z2 lattice gauge theory on superconducting qubits

Physical Review D
Simulating nonequilibirum dynamics of a quantum many-body system is one of the promising applications of quantum computing. We simulate the time evolution of one-dimensional Z2 lattice gauge theory on IBM’s superconducting 156-qubit device, ibm_fez.

High Radiation Resistance in the Binary W‐Ta System Through Small V Additions: A New Paradigm for Nuclear Fusion Materials

Advanced Science, EarlyView.
Refractory high‐entropy alloys exhibit superior radiation tolerance, but face fabrication challenges due to complex compositions. It is demonstrated that reducing the number of alloying elements does not compromise radiation resistance in a novel W‐Ta‐V highly‐concentrated refractory alloy.

The Metric of Yang-Mills Orbit Space on the Lattice

, 2014
We find coordinates, the metric tensor, the inverse metric tensor and the Laplace-Beltrami operator for the orbit space of Hamiltonian SU(2) gauge theory on a finite, rectangular lattice. This is done using a complete axial gauge fixing.

Inhomogeneous coupling perturbations in hamiltonian lattice gauge theory

Nuclear Physics B, 1983
Abstract An inhomogeneous-coupling expansion of hamiltonian lattice gauge theory without fermion fields is presented. It is based upon a decomposition of the (color-)magnetic term of the Kogut-Susskind hamiltonian into two complementary plaquette sets { p 0 } and { p 1 }.

Giant Modulation of Interlayer Coupling in Twisted Bilayer ReS2

Advanced Science, EarlyView.
Twist angle in stacked bilayer ReS2 can modulate 30% of interlayer coupling and the whole range of exciton energy between 1L and 2L ReS2. Abstract Stacking monolayers of two‐dimensional (2D) transition metal dichalcogenides with different twist angles can provide a way to tune their quantum optical and electronic characteristics.

Measure of the path integral in lattice gauge theory

, 2005
We show how to construct the measure of the path integral in lattice gauge theory. This measure contains a factor beyond the standard Haar measure. Such factor becomes relevant for the calculation of a single transition amplitude (in contrast to the ...

Reversal of Spin‐Torque Polarity with Inverting Current Vorticity in Composition‐Graded Layer at the Ti/W Interface

Advanced Electronic Materials, EarlyView.
In compositional gradient materials, variations in electrical conductivity through the film thickness create a gradient in the electric current, resulting in vorticity. This vorticity acts like a magnetic field, whose gradient drives the generation of spin current.

Improving approximate vacuum prepared by the adiabatic quantum computation

IET Quantum Communication, Volume 3, Issue 4, Page 214-217, December 2022., 2022
Abstract According to the quantum adiabatic theorem, we can in principle obtain a true vacuum of a quantum system starting from a trivial vacuum of a simple Hamiltonian. In actual adiabatic digital quantum simulation with finite time length and non‐infinitesimal time steps, we can only obtain an approximate vacuum that is supposed to be a superposition

A Physics‐Based Compact Model for Ferroelectric Capacitors Operating Down to Deep Cryogenic Temperatures for Applications in Analog Memory and Neuromorphic Architectures

Advanced Electronic Materials, EarlyView.
A compact model for ferroelectric thin‐film capacitors operating under different electric fields and temperatures is reported. The model can reproduce polarization switching down to 4 K, making them suitable for quantum computing and space technologies.

Magnetic neutron scattering from spherical nanoparticles with Néel surface anisotropy: atomistic simulations

Journal of Applied Crystallography, Volume 55, Issue 6, Page 1488-1499, December 2022., 2022
Based on the Landau–Lifshitz equation, atomistic simulations of the magnetic neutron scattering from inhomogeneously magnetized spherical nanoparticles with a strong surface anisotropy are carried out.A dilute ensemble of randomly oriented non‐interacting spherical nanomagnets is considered, and its magnetization structure and ensuing neutron ...
