The Smearing of Quasi‐Particles: Signatures in the Entanglement Entropy of Excited Many‐Particle Systems

Advanced Quantum Technologies, EarlyView.
Entanglement reveals hidden structure in quantum matter. We explore how quasi‐particles shape the crossover from area‐law to volume‐law entanglement, using models from spinless fermions to SYK. Our results show a striking linear growth of entanglement with energy, explained as a hallmark of quasi‐particles, offering new insight into the entanglement ...

Effective operators in top physics [PDF]

, 2010
Top interactions beyond the Standard Model can be conveniently described in the framework of gauge-invariant effective operators. We briefly review the general form of the fermion-fermion-gauge boson and fermion-fermion-Higgs interactions arising from ...

Uncovering Exotic Topological Quantum States in Pure and Magnetically‐Doped Pyrite OsS2

Advanced Quantum Technologies, EarlyView.
Pyrite‐structured OsS2 is identified as a fragile topological insulator with an unprecedented 602 meV bandgap, featuring helical surface states and van Hove singularities amenable to ARPES verification. Magnetic doping with Pd, Fe, Ni, or Co induces phase transitions to strong topological insulators, semimetals, 3D quantum anomalous Hall insulators ...

Phases and dynamics of few fermionic impurities immersed in two-dimensional boson droplets

Physical Review Research
We unravel the ground state properties and emergent nonequilibrium dynamics of a mixture consisting of a few spin-polarized fermions embedded in a two-dimensional bosonic quantum droplet. For an increasingly attractive droplet-fermion interaction we find

Fermi Surface Structure Revealed by Quantum Oscillations in Half‐Heusler Semimetal LuAuSn

Rare Metals, EarlyView.
ABSTRACT The Fermi surface structure in the half‐Heusler semimetallic compound LuAuSn was systematically investigated using quantum oscillation studies of high‐quality single crystals and first‐principles calculations. Clear bulk quantum oscillation signals were observed for multiple complementary physical properties, including magnetization, Hall ...

Supersymmetry breaking as the origin of flavor

, 2004
We present an effective flavor model for the radiative generation of fermion masses and mixings based on a SU(5)xU(2) symmetry. We assume that the original source of flavor breaking resides in the supersymmetry breaking sector.

Charge Transport Across Single Molecules at the Metal–Superconductor Interface

Small, EarlyView.
The evolution of Andreev reflection in single‐molecule junctions is probed with the decreasing distance between a normal‐metal tip and a conventional superconductor. Andreev reflection becomes most effective when a molecular orbital straddles the Fermi level.
