Anomalous-magnetic-moment-enhanced Casimir effect
Daisuke Fujii, Katsumasa Nakayama, Kei Suzuki
We theoretically investigate the impact of the anomalous magnetic moment (AMM) of Dirac fermions on the fermionic Casimir effect under magnetic fields. We formulate it as an extens…
Jordan-Wigner mapping between quantum-spin and fermionic Casimir effects
Katsumasa Nakayama, Kei Suzuki
The Jordan-Wigner transformation connects spin operators in one-dimensional spin systems and fermionic operators. In this work, we elucidate the relationship between the finite-siz…
Lifshitz formulas for finite-density Casimir effect
Daisuke Fujii, Katsumasa Nakayama, Kei Suzuki
The Lifshitz formula is well known as a theoretical approach to investigate the Casimir effect at finite temperature. In this Letter, we generalize the Lifshitz formula to the Casi…
Casimir effect in magnetic dual chiral density waves
Daisuke Fujii, Katsumasa Nakayama, Kei Suzuki
We theoretically investigate the Casimir effect originating from Dirac fields in finite-density matter under a magnetic field. In particular, we focus on quark fields in the magnet…
Initial tensor construction and dependence of the tensor renormalization group on initial tensors
Katsumasa Nakayama, Manuel Schneider
We propose a method to construct a tensor network representation of partition functions without singular value decompositions nor series expansions. The approach is demonstrated fo…
