Fermion Bags and A New Origin for a Fermion Mass [PDF]
arXiv, 2014 The fermion bag is a powerful idea that helps to solve fermion lattice field theories using Monte Carlo methods. Some sign problems that had remained unsolved earlier can be solved within this framework. In this work we argue that the fermion bag also gives insight into a new mechanism of fermion mass generation, especially at strong couplings where ...

Fermion masses through four-fermion condensates [PDF]
, 2016 A bstractFermion masses can be generated through four-fermion condensates when symmetries prevent fermion bilinear condensates from forming. This less explored mechanism of fermion mass generation is responsible for making four reduced staggered lattice ...

2D Nonlayered Materials for Transistor Application
Advanced Physics Research, EarlyView.2D nonlayered materials possess a vast material library and have comprehensive applications in transistors. However, at this stage, they hold great potential, but this potential has seen limited exploration compared to 2D layered materials. This review provides statistics on the nonlayered material library, CVD synthesis and characterization, advances ...

An Algebraic Roadmap of Particle Theories
Annalen der Physik, Volume 537, Issue 4, April 2025.The SO(10) grand unified theory, the Georgi–Glashow SU(5) grand unified theory, the Pati–Salam model, the Left–Right Symmetric model, and the Standard model have been studied extensively since the 1970s. Recasting these models in a division algebraic language elucidates how they are each in fact connected.

Nonperturbative definition of the standard models
Physical Review Research, 2020 The standard models contain chiral fermions coupled to gauge theories. It has been a longstanding problem to give such gauged chiral fermion theories a quantum nonperturbative definition.

A note on ultraviolet suppressed quasi-optimal domain wall fermions [PDF]
arXiv, 2002 In a recent work Chiu proposed to modify domain wall fermions that allow in an optimal way fewer number of flavors than in the standard case. This is done using a variant of doamin wall fermions, the so-called truncated overlap fermions. In this note I discuss the possibility to implement his proposal for the original variant of domain wall fermions. I

Orientation‐Dependent Upper Critical Magnetic Field and Density of State for Uranium Ditelluride
Advanced Physics Research, EarlyView.This study investigates the orientation‐dependent upper critical magnetic field (HC2) and the density of states (DOS) in the unconventional superconductor UTe2. These results reveal an anisotropic HC2, with distinct critical fields along different crystallographic axes, highlighting the role of electronic correlations and spin‐triplet pairing.

Short Wavelength Limit of the Dynamic Matsubara Local Field Correction
Contributions to Plasma Physics, EarlyView.ABSTRACT We investigate the short wavelength limit of the dynamic Matsubara local field correction G˜q,zl$$ \tilde{G}\left(\mathbf{q},{z}_l\right) $$ of the uniform electron gas based on direct ab initio path integral Monte Carlo (PIMC) results over an unprecedented range of wavenumbers, q≲20qF$$ q\lesssim 20{q}_{\mathrm{F}} $$, where qF$$ {q}_{\mathrm{

Ionization Potential Depression and Fermi Barrier in Warm Dense Matter: A First‐Principles Approach
Contributions to Plasma Physics, EarlyView.ABSTRACT Ionization potential depression (IPD) is of crucial importance to understand and accurately predict the properties of dense, partially ionized plasmas. Many models of IPD have been developed that, however, exhibit largely varying results. Recently, a novel approach was proposed that is based on first‐principles quantum Monte Carlo simulations ...

Nuclear Physics B, 2020 We derive the conditions for matching high-energy renormalizable Quantum Field Theories onto low-energy nonrenormalizable ones by means of the FDR approach described in [1]. Our procedure works order-by-order in the loop expansion and avoids the addition
