Valley Isospin Controlled Fractional Quantum Hall States in Bilayer Graphene

Physical Review X, 2021
A two-dimensional electron system placed in a magnetic field develops Landau levels, where strong Coulomb interactions lead to the appearance of many-body correlated ground states. Quantum numbers similar to the electron spin enable the understanding and

Isospin order in superconducting magic-angle twisted trilayer graphene

Nature Physics, 2021
The discovery of magic-angle twisted trilayer graphene unlocks various properties of the superconducting phase, such as violation of the Pauli limit and re-entrant superconductivity at large in-plane magnetic fields1–3.

Isospin Pomeranchuk effect in twisted bilayer graphene

Nature, 2020
In condensed-matter systems, higher temperatures typically disfavour ordered phases, leading to an upper critical temperature for magnetism, superconductivity and other phenomena.

Isospin balls

Physical Review Letters, 1987
We show that nontopological solitons are predicted by a class of chiral models which incorporate the QCD scale anomaly. These solitons exist for all values of isospin which exceed a critical value Ic.

Isospin and spin-isospin dipole oscillations in12C

Lettere al Nuovo Cimento, 1972
Recent measurements of the cross-sections for excitation of 12C by electron scattering provide us with values of the longitudinal form factor tZZ(q, Ex) and transverse form factor i~r(q, Ex) for values of the excitation energy Ex in the giant resonance region and large values of momentum transfer q(> 0.5 fm-1).

QCD Constraints on Isospin-Dense Matter and the Nuclear Equation of State.

Physical Review Letters
Understanding the behavior of dense hadronic matter is a central goal in nuclear physics as it governs the nature and dynamics of astrophysical objects such as supernovae and neutron stars. Because of the nonperturbative nature of quantum chromodynamics (

Isospin and spin-isospin modes in charge-exchange reactions

AIP Conference Proceedings, 1999
The microscopic structure of the Gamow-Teller resonance (GTR) and spin-dipole resonance (SDR) in Bi-208 has been investigated in the Pb-208(He-3,tp)Pb-207 reaction at E(He-3) = 450 MeV and very forward scattering angles. The partial and total branching ratios and the escape widths for GTR and SDR decay to the residual neutron-hole states in Pb-207 were
