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…
