Non-degeneracy of closed orbits for generic potentials [PDF]
arXiv, 2023 We prove that Ma{\~n}{\'e} generic convex Hamiltonians have only non-degenerate periodic orbits on a given energy level. This result was stated, but not proved, in the literature.

Minimal Length Uncertainty Relation and Hydrogen Atom [PDF]
, 1999 We propose a new approach to calculate perturbatively the effects of a particular deformed Heisenberg algebra on energy spectrum. We use this method to calculate the harmonic oscillator spectrum and find that corrections are in agreement with a previous ...

Electronic properties and optical absorption of rectangular β12-borophene quantum dot
AIP AdvancesUsing the tight-binding model, we studied the electronic and optical properties of rectangular β12-borophene quantum dot (RBQD). We considered the effects of different lengths and widths on the energy levels and optical spectra of RBQD.

Relativistic harmonic oscillator model for quark stars
, 2008 The relativistic harmonic oscillator (RHO) model of hadrons is used to study quark stars. The mass-radius relationship is obtained and compared with bag model of quark star, using Tolman-Oppenheimer-Volkoff equation. In this model, the outward degenerate

History and Some Aspects of the Lamb Shift
Physics, 2020 Radiation is a process common to classical and quantum systems with very different effects in each regime. In a quantum system, the interaction of a bound electron with its own radiation field leads to complex shifts in the energy levels of the electron,

Dynamics and uncertainty for maximally entangled bipartite system constrained on a helicoid
European Physical Journal C: Particles and Fields, 2022 The classical and quantum dynamics of particles constrained on a right helicoid is discussed via Dirac approach. We show how the uncertainty in measurement for observables of maximally entangled system is affected by the total number of constrained ...

Valley Degenerate 2D Electrons in the Lowest Landau Level [PDF]
Phys. Rev. B 89, 041107 (2014), 2012 We report low temperature magnetotransport measurements on a high mobility (\mu=325,000 cm^2/V sec) 2D electron system on a H-terminated Si(111) surface. While low magnetic field data indicate a six-fold valley degenerate system, we observe the integral quantum Hall effect at all filling factors \nu<=6 and find that \nu=2 develops in an unusually ...

Physical Review ResearchOpen quantum systems with nearly degenerate energy levels have been shown to exhibit long-lived metastable states in the approach to equilibrium, even when modelled with certain Lindblad-form quantum master equations.

Ultrafast carrier dynamics in Landau-quantized graphene
Nanophotonics, 2015 In an external magnetic field, the energy of massless charge carriers in graphene is quantized into non-equidistant degenerate Landau levels including a zero-energy level.

Trigonal warping and Berry’s phase Npi in ABC-stacked multilayer graphene. [PDF]
, 2009 The electronic band structure of ABC-stacked multilayer graphene is studied within an effective mass approximation. The electron and hole bands touching at zero energy support chiral quasiparticles characterized by Berry’s phase Nπ for N-layers ...
