Relativistic bound states within Basis Light-Front Quantization [PDF]

, 2020
We investigate the relativistic bound states in the non-perturbative regime with the light-front Hamiltonian formalism. Our studies focus on two systems, the relativistic Yukawa model and the light unflavored mesons.

A 3+1 Dimensional LF Model with Spontaneous χ SB [PDF]

, 1998
Light-front (LF) quantization provides an intuitive (physical basis!) description of hadron structure that stays close to the relevant degrees of freedom in high energy scattering: many high-energy scattering processes probe hadrons along a light-like ...

Gluon skewed generalized parton distributions of proton from a light-front Hamiltonian approach

Physics Letters B
We calculate all leading-twist gluon generalized parton distributions (GPDs) inside the proton at nonzero skewness using the basis light-front quantization framework.

Three-dimensional imaging of proton in basis light-front quantization [PDF]

Hadron Spectroscopy and Structure, 2020
We employ an effective Hamiltonian that includes the transverse and longitudinal confinement and the one-gluon exchange interaction with fixed coupling constant. By solving the eigenvalue equation in basis light-front quantization (BLFQ), we generate the light-front wavefunctions (LFWFs) for the nucleon in the valence quark Fock space.

Multimode Oxide‐Based Optoelectronic Memtransistor for In‐Sensor Vision Processing

Advanced Functional Materials, EarlyView.
A multimode optoelectronic memtransistor (OEMT) is demonstrated for vision explainable artificial intelligence (VXAI) hardware. By integrating optical sensing, electrical masking, and non‐volatile memory, the device enables key operations required for generating saliency information.

Applications of Basis Light-Front Quantization to QED [PDF]

Nuclear Physics B - Proceedings Supplements, 2014
Hamiltonian light-front quantum field theory provides a framework for calculating both static and dynamic properties of strongly interacting relativistic systems. Invariant masses, correlated parton amplitudes and time-dependent scattering amplitudes, possibly with strong external time-dependent fields, represent a few of the important applications. By

An Adaptive Inhibitory WSe2 Transistor for Retinomorphic In‐Sensor Image Processing

Advanced Functional Materials, EarlyView.
Conventional retinomorphic devices typically require deliberate gate‐bias tuning for each illumination condition. In this paper, we demonstrate an adaptive inhibitory WSe2 transistor that uses photo‐induced regime shift between the subthreshold and accumulation modes to achieve decision‐free, intensity‐adaptive image processing within a single pixel ...

Recognizing Voice Over IP: A Robust Front-End for Speech Recognition on the World Wide Web [PDF]

, 2001
The Internet Protocol (IP) environment poses two relevant sources of distortion to the speech recognition problem: lossy speech coding and packet loss. In this paper, we propose a new front-end for speech recognition over IP networks.

Comparison of two Minkowski-space approaches to heavy quarkonia

European Physical Journal C: Particles and Fields, 2017
In this work we compare mass spectra and decay constants obtained from two recent, independent, and fully relativistic approaches to the quarkonium bound-state problem: the Basis Light-Front Quantization approach, where light-front wave functions are ...
