Dark sector effective field theory
Journal of High Energy Physics, 2023 We introduce the effective field theory of two different light dark particles interacting with the standard model (SM) light states in a single vertex, termed dark sector effective field theory (DSEFT). We focus on the new light particles with spin up to

Strain Tuning the Occupation of Candidate Topological Weyl States in W‐Doped MoTe2
Advanced Science, EarlyView.The present study investigates strain‐induced modifications of the electronic structure in the Weyl semimetal Td${\rm T}_d$‐Mo0.91W0.09Te2${\mathrm{Mo}}_{0.91}{\mathrm{W}}_{0.09}{\mathrm{Te}}_{2}$ using hard X‐ray angle‐resolved photoemission spectroscopy.

Radiation of light fermions in heavy fermion production [PDF]
Nuclear Physics B, 1995 Recent analytic calculations on the rate for the production of a pair of massive fermions in $e^+ e^-$ annihilation plus real or virtual radiation of a pair of massless fermions are discussed. The contributions for real and virtual radiation are displayed separately.

Size dependence of heavy-fermion behavior in CeAl2
, 2013 Heavy-fermion compound CeAl2 has a Kondo temperature TK of 5 K and a /Neel temperature TN of 3.8 K. As the dimensions of specimen decrease, the size effect was shown as the suppression of TK and the magnitude of anti-ferromagnetic anomaly in specific ...

Fermi-bounce cosmology and the fermion curvaton mechanism
Physics Letters B, 2015 A nonsingular bouncing cosmology can be achieved by introducing a fermion field with BCS condensation occurring at high energy scales. In this paper we are able to dilute the anisotropic stress near the bounce by means of releasing the gap energy density

Advanced Science, EarlyView.External pressure directly tunes the breathing distortion of the kagome lattice in Fe3Sn2, suppressing it near 15 GPa and reversing it at higher pressures. This structural modulation drives a cascade of Lifshitz transitions, reconstructs the Fermi surface, strengthens electronic correlations and carrier localization, and modifies ultrafast electron ...

Triplet fermions and Dirac fermions in borophene
Physical Review B, 2017 Borophene is a monolayer materials made of boron. A perfect planar boropehene called $β_{12}$ borophene has Dirac cones and they are well reproduced by a tight-binding model according to recent experimental and first-principles calculation results. We explicitly derive a Dirac theory for them. Dirac cones are gapless when the inversion symmetry exists,

Physics Letters B, 1974 Abstract Spontaneous violation of super-gauge symmetries is considered. One consequence must be the emergence of a particle with spin 1 2 and mass zero.

Fermion bag approach to fermion sign problems
, 2013 The fermion bag approach is a new method to tackle fermion sign problems in lattice field theories. Using this approach it is possible to solve a class of sign problems that seem unsolvable by traditional methods.
