Melting of the critical behavior of a Tomonaga-Luttinger liquid under dephasing

Author(s): Jean-Sébastien Bernier, Ryan Tan, Chu Guo, Corinna Kollath, and Dario PolettiStrongly correlated quantum systems often display universal behavior as, in certain regimes, their properties are found to be independent of the microscopic details of the underlying system. An example of such a situation is the Tomonaga-Luttinger liquid description...

Higher-order ferromagnetic resonances in out-of-plane saturated Co/Au magnetic multilayers

Author(s): L. Fallarino, S. Stienen, R. A. Gallardo, J. A. Arregi, V. Uhlíř, K. Lenz, R. Hübner, A. Oelschlägel, O. Hellwig, and J. LindnerArtificial ferromagnetic (FM)/nonmagnetic multilayers, with large enough FM thickness to prevent the dominance of interface anisotropies, offer a straightforward insight into the understanding and control of perpendicular...

Superconducting islands with topological Josephson junctions based on semiconductor nanowires

Author(s): J. Ávila, E. Prada, P. San-Jose, and R. AguadoWe theoretically study superconducting islands based on semiconductor-nanowire Josephson junctions and take into account the presence of subgap quasiparticle excitations in the spectrum of the junction. Our method extends the standard model Hamiltonian for a superconducting charge qubit and replaces...[Phys....

Unconventional topological insulators from extended topological band degeneracies

Author(s): Zhongbo YanA general and beautiful picture for the realization of topological insulators is that the mass term of the Dirac model has a nodal surface wrapping one Dirac point. We show that this geometric picture based on Dirac points can be generalized to extended band degeneracies with nontrivial topological ...[Phys. Rev. B 102, 115151]...

Accessing long timescales in the relaxation dynamics of spins coupled to a conduction-electron system using absorbing boundary conditions

Author(s): Michael Elbracht and Michael PotthoffThe relaxation time of a classical spin interacting with a large conduction-electron system is computed for a weak magnetic field, which initially drives the spin out of equilibrium. We trace the spin and the conduction-electron dynamics on a timescale which exceeds the characteristic electronic sca...[Phys....

Pressure-induced suppression of ferromagnetism in ${\mathrm{CePd}}_{2}{\mathrm{P}}_{2}$

Author(s): T. A. Elmslie, D. VanGennep, W. Bi, Y. Lai, S. T. Weir, Y. K. Vohra, R. E. Baumbach, and J. J. HamlinThe correlated electron material CePd2P2 crystallizes in the ThCr2Si2 structure and orders ferromagnetically at 29 K. Prior work by Lai et al. [Phys. Rev. B 97, 224406 (2018)] found evidence for a ferromagnetic quantum critical point induced...

Isotope effects in x-ray absorption spectra of liquid water

Author(s): Chunyi Zhang, Linfeng Zhang, Jianhang Xu, Fujie Tang, Biswajit Santra, and Xifan WuThe isotope effects in x-ray absorption spectra of liquid water are studied by a many-body approach within electron-hole excitation theory. The molecular structures of both light and heavy water are modeled by path-integral molecular dynamics based on the advanced...

Critical role of the sign structure in the doped Mott insulator: Luther-Emery versus Fermi-liquid-like state in quasi-one-dimensional ladders

Author(s): Hong-Chen Jiang, Shuai Chen, and Zheng-Yu WengThe mechanism of superconductivity in a purely interacting electron system has been one of the most challenging issues in condensed matter physics. In the BCS theory, the Landau's Fermi liquid is the ground state of weakly interacting fermions dictated by the fermion sign structure, and the supercon...[Phys....

Twofold quadruple Weyl nodes in chiral cubic crystals

Author(s): Tiantian Zhang, Ryo Takahashi, Chen Fang, and Shuichi MurakamiUnlike conventional Weyl nodes, unconventional ones carry a quantized monopole charge C>1, and their existence needs the protection of crystalline symmetries in addition to translation symmetry. There have been many studies on unconventional Weyl nodes, yet we have so far missed...
