Microscopic Realization of Topologically Quantized Alignment in Fast-Rotating Nuclei
Ganlong Ding, Sibo Wang, Hiroyuki Tajima +3
We present the first quantitative microscopic realization of topologically quantized alignment in a finite nuclear system. The realization is obtained by exact diagonalization of a…
Relativistic dynamical effects in proton emission: the Wentzel-Kramers-Brillouin method for 1+1 dimensional Dirac equation
Guangping Chen, Wenmin Deng, Ganlong Ding +3
Starting from the dimensional (one spatial and one temporal dimension) Dirac equation, we employ the Wentzel-Kramers-Brillouin (WKB) approximation to derive the corresponding…
Functional methods for quantum thermodynamics
Sibo Wang, Samuel Degen, Haozhao Liang
The functional renormalization group provides a nonperturbative and systematically improvable route to constructing density functionals for quantum many-body systems from microscop…
Collective quantum tunneling with time-dependent generator coordinate method
Wenmin Deng, Guangping Chen, Ganlong Ding +3
Inspired by the work of McGlynn and Simenel [Phys. Rev. C {\bf 102}, 064614 (2020)], this study investigates the quantum tunneling of two interacting distinguishable particles in t…
Non-Hermitian Renormalization Group from a Few-Body Perspective
Hiroyuki Tajima, Masaya Nakagawa, Haozhao Liang +1
Non-Hermiticity plays a fundamental role in open quantum systems and describes a wide variety of effects of interactions with environments, including quantum measurement. However,…
Comparative study of quartet superfluid state: Quartet Bardeen-Cooper-Schrieffer theory and generalized Nambu-Gor'kov formalism
Yixin Guo, Hiroyuki Tajima, Haozhao Liang
We theoretically investigate a quartet superfluid state in fermionic matter by using the quartet Bardeen-Cooper-Schrieffer (BCS) variational theory and the Green's function method.…
Thermal liquid-gas phase transition in a quasi-one-dimensional dipolar Fermi gas
Lanxuan Gao, Koki Takayama, Hiroyuki Tajima +2
We theoretically investigate the thermodynamic properties of a quasi-one-dimensional single-component dipolar Fermi gas at finite temperatures. A self-bound fermionic droplet can b…
Tripling Fluctuations and Peaked Sound Speed in Fermionic Matter
Hiroyuki Tajima, Kei Iida, Toru Kojo +1
A crossover involving three-fermion clusters is relevant to the hadron-quark crossover, which, if occurring in a neutron star, could naturally reproduce the dense-matter equation o…
Time-dependent Relativistic Hartree-Fock model with spherical symmetry
Jing Geng, Zhi Heng Wang, Peng Wei Zhao +3
This work establishes the time-dependent relativistic Hartree-Fock (TD-RHF) model with spherical symmetry for the first time. The time-dependent integro-differential Dirac equation…
Probing Goldstino excitation through the tunneling transport in a Bose-Fermi mixture with explicitly broken supersymmetry
Tingyu Zhang, Yixin Guo, Hiroyuki Tajima +1
We theoretically investigate the tunneling transport in a repulsively interacting ultracold Bose-Fermi mixture. A two-terminal model is applied to such a mixture and the supersymme…
Non-relativistic trace anomaly and equation of state in dense fermionic matter
Hiroyuki Tajima, Kei Iida, Haozhao Liang
We theoretically investigate a non-relativistic trace anomaly and its impact on the low-temperature equation of state in spatially one-dimensional three-component fermionic systems…
Magnonic spin current shot noise in an itinerant Fermi gas
Tingyu Zhang, Hiroyuki Tajima, Haozhao Liang
Spin transport phenomena at strongly-correlated interfaces play central roles in fundamental physics as well as spintronic applications. To anatomize spin-transport carriers, we pr…
A Data-Driven Density Functional Model for Nuclear Systems
Zu-Xing Yang, Xiao-Hua Fan, Zhi-Pan Li +1
Through ensemble learning with multitasking and complex connection neural networks, we aggregated nuclear properties, including ground state charge radii, binding energies, and sin…
