Simulating Quantum Field Theories with Boundaries in Curved Spacetimes Using Open Spin Systems
Shunichiro Kinoshita, Keiju Murata, Daisuke Yamamoto +1
We develop a framework to simulate quantum field theories (QFTs) with boundaries in -dimenmsional curved spacetimes by employing open spin systems. Building upon our previou…
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…
Twisted kink crystal in holographic superconductor
Masataka Matsumoto, Ryosuke Yoshii
Holographic superconductor model represents various inhomogeneous solutions with homogeneous sources. In this paper, we study inhomogeneous structures in the presence of the homoge…
Kink Crystalline Condensate and Multi-kink Solution in Holographic Superconductor
Masataka Matsumoto, Shin Nakamura, Ryosuke Yoshii
The theory of superconductivity can be divided into two groups depending on whether it has multi-kink solutions. For example, the BCS theory and the Gross-Neveu model have metastab…
Ground state modulations in the model
Antonino Flachi, Guglielmo Fucci, Muneto Nitta +2
In this work we examine a system consisting of a confined one-dimensional arrangement of atoms that we describe by using the 2-dimensional model, restricted to…
Confining solitons in the Higgs phase of model: Self-consistent exact solutions in large- limit
Muneto Nitta, Ryosuke Yoshii
The quantum model is in the confining (or unbroken) phase with a full mass gap in an infinite space, while it is in the Higgs (broken or deconfinement) phase a…
Self-consistent Analytic Solutions in Twisted Model in the Large- Limit
Muneto Nitta, Ryosuke Yoshii
We construct self-consistent analytic solutions in the model in the large- limit, in which more than one Higgs scalar component take values inside a single…
Casimir Force for the Model
Antonino Flachi, Muneto Nitta, Satoshi Takada +1
In this work, we derive exact self-consistent solutions to the gap equations of the model on a finite interval with Dirichlet boundary conditions in the large-$…
Self-Consistent Large- Analytical Solutions of Inhomogneous Condensates in Quantum Model
Muneto Nitta, Ryosuke Yoshii
We give, for the first time, self-consistent large- analytical solutions of inhomogeneous condensates in the quantum model in the large- limit. We find a…
Sign Flip in the Casimir Force for Interacting Fermion Systems
Antonino Flachi, Muneto Nitta, Satoshi Takada +1
In this work we consider a fermionic chain of finite length . Fermions are allowed to interact and are forced to obey boundary conditions, thus altering the process of conden…
Out-of-time-order correlators in quantum mechanics
Koji Hashimoto, Keiju Murata, Ryosuke Yoshii
The out-of-time-order correlator (OTOC) is considered as a measure of quantum chaos. We formulate how to calculate the OTOC for quantum mechanics with a general Hamiltonian. We dem…
