Bulk angular momentum and Hall viscosity in chiral superconductors [PDF]
, 2014 We establish the Berry-phase formulas for the angular momentum (AM) and the Hall viscosity (HV) to investigate chiral superconductors (SCs) in two and three dimensions.

Stationary scalar and vector clouds around Kerr-Newman black holes
, 2020 Massive bosons in the vicinity of Kerr-Newman black holes can form pure bound states when their phase angular velocity fulills the synchronisation condition, i.e. at the threshold of superradiance.

, 2018 We find vacuum solutions such that massive gravitons are confined in a local spacetime region by their gravitational energy in asymptotically flat spacetimes in the context of the bigravity theory.

Schwinger's oscillator method, supersymmetric quantum mechanics and massless particles
Revista Brasileira de Ensino de FísicaWe consider Schwinger's method of angular momentum addition using the SU(2) algebra with both a fermionic and a bosonic oscillator. We show that the total spin states obtained are: one boson singlet state and an arbitrary number of spin-1/2 states, the ...

Levinson theorem for Dirac particles in two dimensions
, 1998 The Levinson theorem for nonrelativistic quantum mechanics in two spatial dimensions is generalized to Dirac particles moving in a central field. The theorem relates the total number of bound states with angular momentum $j$ ($j=\pm 1/2, \pm 3/2, ... $),

Physical Review CA general method is proposed to obtain the distribution of the total quantum number M for a set of N identical fermions with momentum j, which is a cornerstone of the nuclear shell model. This can be performed using a recursive procedure on N, yielding closed-form expressions, which are found to be linear combinations of piecewise polynomials.

Distortion of Wigner molecules : pair function approach
, 2008 We considered a two dimensional three electron quantum dot in a magnetic field in the Wigner limit. A unitary coordinate transformation decouples the Hamiltonian (with Coulomb interaction between the electrons included) into a sum of three independent ...

Levinson theorem in two dimensions
, 1998 A two-dimensional analogue of Levinson's theorem for nonrelativistic quantum mechanics is established, which relates the phase shift at threshold(zero momentum) for the $m$th partial wave to the total number of bound states with angular momentum $m\hbar ...

Advanced Functional Materials, EarlyView.This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.
