Dynamical invariant based shortcut to equilibration in open quantum systems
Mohamed Boubakour; Shimpei Endo; Thomás Fogarty; Thomas Busch
Quantum Science and Technology, IOP Publishing, 10, 025036, 13 Mar. 2025, Peer-reviwed, Abstract

We propose using the dynamical invariants, also known as the Lewis–Riesenfeld invariants, to
speed-up the equilibration of a driven open quantum system. This allows us to reverse engineer the
time-dependent master equation that describes the dynamics of the open quantum system and sys-
tematically derive a protocol that realizes a shortcut to equilibration. The method does not require
additional constraints on the timescale of the dynamics beside the Born-Markov approximation and
can be generically applied to boost single particle quantum engines significantly. We demonstrate it
with the damped harmonic oscillator, and show that our protocol can achieve a high-fidelity control
in shorter timescales than simple non-optimized protocols. We find that the system is heated during
the dynamics to speed-up the equilibration, which can be considered as an analogue of the Mpemba
effect in quantum control.

Universality of Efimov states in highly mass-imbalanced cold-atom mixtures with van der Waals and dipole interactions
Kazuki Oi; Pascal Naidon; Shimpei Endo
Last, Physical Review A, American Physical Society (APS), 110, 3, 033305, 03 Sep. 2024, Peer-reviwed, We study three-body systems in a mass-imbalanced, two-component, cold-atom mixture, and we investigate the three-body parameter of their Efimov states for both bosonic and fermionic systems, with a major focus on the Er-Er-Li Efimov states. For a system interacting solely via van der Waals interactions, the van der Waals universality of the three-body parameter is analytically derived using the quantum defect theory. With the addition of a perturbative dipole interaction between the heavy atoms, the three-body parameters of the bosonic and fermionic Efimov states are found to behave differently. When the dipole interaction is as strong as the van der Waals interaction, corresponding to realistic Er-Er-Li Efimov states, we show that the van der Waals universality persists once the effects of the nonperturbative dipole interaction are into the s-wave and p-wave scattering parameters between the heavy atoms. For a dipole interaction much stronger than the van der Waals interaction, we find that the universality of the Efimov states can be alternatively characterized by a quasi-one-dimensional scattering parameter due to a strong anisotropic deformation of the Efimov wave functions. Our work thus clarifies the interplay of isotropic and anisotropic forces in the universality of the Efimov states. Based on the renormalized van der Waals universality, the three-body parameter is estimated for specific isotopes of Er-Li cold-atom mixtures.

Topological phases and edge modes of an uneven ladder
Wen-Chuang Shang; Yi-Ning Han; Shimpei Endo; Chao Gao
Chinese Physics B, IOP Publishing, 33, 8, 080202-080202, 01 Jul. 2024, Abstract

We investigate the topological properties of a two-chain quantum ladder with uneven legs, i.e., the two chains differ in their periods by a factor of 2. Such an uneven ladder presents rich band structures classified by the closure of either direct or indirect bandgaps. It also provides opportunities to explore fundamental concepts concerning band topology and edge modes, including the difference of intracellular and intercellular Zak phases, and the role of the inversion symmetry (IS). We calculate the Zak phases of the two kinds and find excellent agreement with the dipole moment and extra charge accumulation. We also find that configurations with IS feature a pair of degenerate two-side edge modes emerging as the closure of the direct bandgap, while configurations without IS feature one-side edge modes emerging as not only the closure of both direct and indirect bandgaps but also within the band continuum. Furthermore, by projecting to the two sublattices, we find that the effective Bloch Hamiltonian corresponds to that of a generalized Su–Schrieffer–Heeger model or the Rice–Mele model whose hopping amplitudes depend on the quasimomentum. In this way, the topological phases can be efficiently extracted through winding numbers. We propose that uneven ladders can be realized by spin-dependent optical lattices and their rich topological characteristics can be examined by near future experiments.

Eigenvalues of Two-State Quantum Walks Induced by the Hadamard Walk

Lead, Entropy, MDPI AG, 22, 1, 127-127, 20 Jan. 2020, Peer-reviwed, Existence of the eigenvalues of the discrete-time quantum walks is deeply related to localization of the walks. We revealed, for the first time, the distributions of the eigenvalues given by the splitted generating function method (the SGF method) of the space-inhomogeneous quantum walks in one dimension we had treated in our previous studies. Especially, we clarified the characteristic parameter dependence for the distributions of the eigenvalues with the aid of numerical simulation.

Weak limit theorem of a two-phase quantum walk with one defect
Shimpei Endo; Takako Endo; Norio Konno; Etsuo Segawa; Masato Takei
Lead, Interdisciplinary Information Sciences, Vol.22, 17-29 (2016), Graduate School of Information Sciences, Tohoku University, 22, 1, 17-29, Mar. 2016, Peer-reviwed, We attempt to analyze a one-dimensional space-inhomogeneous quantum walk (QW)

with one defect at the origin, which has two different quantum coins in

positive and negative parts. We call the QW "the two-phase QW", which we

treated concerning localization theorems [10]. The two-phase QW has been

expected to be a mathematical model of the topological insulator [16] which is

an intense issue both theoretically and experimentally [3,5,11]. In this paper,

we derive the weak limit theorem describing the ballistic spreading, and as a

result, we obtain the mathematical expression of the whole picture of the

asymptotic behavior. Our approach is based mainly on the generating function of

the weight of the passages. We emphasize that the time-averaged limit measure

is symmetric for the origin [10], however, the weak limit measure is

asymmetric, which implies that the weak limit theorem represents the asymmetry

of the probability distribution.

冷却原子気体のBEC-BCSクロスオーバーにおける多体効果の理論的研究
遠藤 晋平
Japan Society for the Promotion of Science, Grants-in-Aid for Scientific Research Grant-in-Aid for JSPS Fellows, The University of Tokyo, Grant-in-Aid for JSPS Fellows, Principal investigator, 散乱長が大きな3粒子系では、離散スケーリング則を示す3粒子束縛状態が普遍的に現れ、Efimov状態とよばれる。Efimov状態のエネルギースケールを決定する重要なパラメータとして3体パラメータがある。近年、3体パラメータが普遍的に振舞うことが冷却原子気体の実験で発見された。昨年までの研究で、私は冷却原子系特有のvan der Waals型相互作用をする系について、3体パラメータが普遍的に振舞うことの物理的起源を解明した。本年度の研究では、vall der Waals型以外の様々な相互作用をする3粒子問題を解き、3体パラメータが普遍性がvan der Waals型以外の様々な相互作用をする系について普遍的に成立することを発見した。また、相互作用の遠方での減衰の速さに依存して、3体パラメータのUniversality classの分類が可能なことを発見し、これらの成果をPhysical Review Letters誌に発表した。 Efimov状態は冷却原子気体以外にも、^4Heクラスター、中性子過剰原子核、マグノン等で現れる可能性が示唆されており、本研究はこれら様々な系での少数系の理解に本研究が大きく貢献するものと期待される。また、本研究は相互作用が散乱長が大きな領域でのボソン系の振舞いを研究したものであるが、Fermion系においてもEfimv状態が現れうることが知られており、Boson系、Fermion系双方の少数・多体系の振舞いの理解にも有用となることが期待される。 また質量インバランスのある系における3体パラメータの振舞いに関する研究も行った。その結果、同種粒子系の場合と類似の形をしたHyper-radial repulsionが現れることを発見し、3体パラメータが普遍的に振舞う可能性があることを見出した。, 11J07049
