Dynamical de Sitter conjecture and quintessence model
Muneto Nitta, Kunihito Uzawa
The de Sitter conjecture yields a severe bound on possible vacua for a consistent quantum gravity. We extend the de Sitter conjecture by taking into account dynamics of the scalar…
Emergent chirality and superfluidity of parity-doubled baryons in neutron stars
Shigehiro Yasui, Muneto Nitta, Chihiro Sasaki
We propose novel superfluids induced by the parity-doubled baryons. The parity-doubled baryons, i.e., a nucleon with spin-parity and an excited nucleon $N^…
Glueballonia as Hopfions
Yuki Amari, Muneto Nitta, Chihiro Sasaki +3
We work out the Hopfion description of glueballs by inclusively comparing the energy spectra obtained by quantizing Hopfions with experimental data and lattice QCD. Identifying a H…
Fermion Casimir effect and magnetic Larkin-Ovchinnikov phases
Antonino Flachi, Muneto Nitta, Satoshi Takada +1
This paper explores how magnetic fields affect the Casimir effect within the context of a simple quasi-1D interacting fermionic system. A novel phenomenon emerges, resulting from t…
Quantum Knots that Never Come Untied
Michikazu Kobayashi, Yuta Nozaki, Yuya Koda +1
Lord Kelvin proposed that atoms form hydrodynamic vortex knots. However, they typically untie through reconnections, i. e., local cut-and-slice events, unlike stable vortex unknots…
