Raman Response of Monolayer Graphene Upon Varying TCNE Adsorption

open access: yesAdvanced Physics Research, EarlyView.
Low TCNE loading induces p‐type doping in monolayer graphene without significantly disturbing local lattice symmetry, due to a structurally favorable molecular arrangement. At higher TCNE concentrations, the D‐band emergence indicates increasing symmetry breaking. TCNE thus enables concentration‐dependent tuning of graphene's electronic properties with

Carroll Fermions

open access: yesProceedings of Corfu Summer Institute 2023 "School and Workshops on Elementary Particle Physics and Gravity" — PoS(CORFU2023)
Using carefully chosen projections, we consider different Carroll limits of relativistic Dirac fermions in any spacetime dimensions. These limits define Carroll fermions of two types: electric and magnetic. The latter type transforms as a reducible but indecomposable representation of the Carroll group.

Boson Fermion Symmetries and Dynamical Supersymmetries for Odd-Odd Nuclei [PDF]

open access: yes, 1985
Odd-odd nuclei are modeled by the application of symmetries and supersymmetries in IBM/IBFM. Odd-odd nuclei are described as a mixed system if bosons and fermions by a Hamiltonian consisting of three contributions: the IBM Hamiltonian, a one-fermion and ...

Boson-fermion mapping of collective fermion-pair algebras

open access: yes, 1995
We construct finite Dyson boson-fermion mappings of general collective algebras extended by single-fermion operators. A key element in the construction is the implementation of a similarity transformation which transforms boson-fermion images obtained ...

Neutrino Oscillation in a Minimal Length Spacetime

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We investigate how neutrino oscillations are modified in a non‐commutative spacetime characterized by a minimal length scale, described by the Quesne–Tkachuk algebra. By incorporating the algebra's deformation parameter β$$ \beta $$ into the effective neutrino mass, we derive the two‐flavor oscillation probability in this non‐commutative ...

Pseudomagnetic fields for classical waves in two‐dimensional artificial lattices: Mechanisms and applications

open access: yesInfoScience, EarlyView.
Pseudomagnetic fields make light and sound emulate charged particles in magnetic fields, enabling magnetic‐free signal processing. This Review summarizes their origins, three implementations in two‐dimensional artificial lattices, and applications in energy localization and robust transport, guiding the design of topological integrated devices ...

Correlation effects in boson-fermion plasmas [PDF]

open access: yes, 2000
A system of charged bosons and electrons interacting with each other via the Coulomb potential comprises an interesting two-component plasma. Boson-fermion mixtures are recently of particular attention because of their relevance in some high-Tc ...

Atomic‐Scale Control of Substrate‐Spin Coupling Via Vertical Manipulation of a 2D Metal‐Organic Framework

open access: yesSmall, EarlyView.
A slightly buckled 2D kagome metal‐organic framework (MOF) adsorbed on Ag(111) hosts localized spins which are Kondo‐screened by the underlying metal substrate. Using the tip of a scanning tunneling microscope, the MOF can be vertically manipulated to controllably change its adsorption height and with it, the Kondo coupling strength.

Is the Composite Fermion a Dirac Particle?

open access: yesPhysical Review X, 2015
We propose a particle-hole symmetric theory of the Fermi-liquid ground state of a half-filled Landau level. This theory should be applicable for a Dirac fermion in the magnetic field at charge neutrality, as well as for the ν=1/2 quantum Hall ground ...
