Carbon Chain Chemistry in Hot-Core Regions around Three Massive Young Stellar Objects Associated with 6.7 GHz Methanol Masers
Kotomi Taniguchi, Eric Herbst, Liton Majumdar +7
We have carried out observations of CCH (), CHCN (), and three C isotopologues of HCN () toward three massive young stellar objects (MYSOs)…
Power-Law Decay Exponents of Nambu-Goldstone Transverse Correlations
Tohru Koma
We study a quantum antiferromagnetic Heisenberg model on a hypercubic lattice in three or higher dimensions . When a phase transition occurs with the continuous symmetry br…
Quantum search of matching on signed graphs
Etsuo Segawa, Yusuke Yoshie
We construct a quantum searching model of a signed edge driven by a quantum walk. The time evolution operator of this quantum walk provides a weighted adjacency matrix induced by t…
Chemical composition in the IRAS 16562--3959 high-mass star-forming region
Kotomi Taniguchi, Andrés E. Guzmán, Liton Majumdar +2
We have analyzed the Atacama Large Millimeter/submillimeter Array (ALMA) cycle 2 data of band 6 toward the G345.4938+01.4677 massive young protostellar object (G345.5+1.47 MYSO) in…
Stability of the Spectral Gap for Lattice Fermions
Tohru Koma
It is widely believed that the spectral gap above the Fermi sea ground state of lattice free fermions is stable against generic weak interactions. Quite recently, Hastings presente…
Field-selective classical spin liquid and magnetization plateaus on kagome lattice
Kunio Tokushuku, Tomonari Mizoguchi, Masafumi Udagawa
We obtain a classical spin liquid (CSL) phase by applying a magnetic field in -- Ising model on a kagome lattice. As we proved in the previous study [Phys. Rev. Lett…
