A scattering matrix formulation of the topological index of interacting fermions in one-dimensional superconductors
Dganit Meidan, Alessandro Romito, Piet W. Brouwer
We construct a scattering matrix formulation for the topological classification of one-dimensional superconductors with effective time reversal symmetry in the presence of interact…
Current amplification and relaxation in Dirac systems
Alexandra Junck, Gil Refael, Felix von Oppen
We study how electron-electron (e-e) interactions affect the current carried by excited electrons and holes in Dirac systems such as graphene or topological insulators. We find tha…
Ultrafast modulation of the chemical potential in BaFeAs by coherent phonons
L. X. Yang, G. Rohde, T. Rohwer +18
Time- and angle-resolved extreme ultraviolet photoemission spectroscopy is used to study the electronic structure dynamics in BaFeAs around the high-symmetry points and…
Topology of surfaces for molecular Stark energy, alignment and orientation generated by combined permanent and induced electric dipole interactions
Burkhard Schmidt, Bretislav Friedrich
We show that combined permanent and induced electric dipole interactions of polar and polarizable molecules with collinear electric fields lead to a sui generis topology of the cor…
Thoughts on Barnette's Conjecture
Helmut Alt, Michael S. Payne, Jens M. Schmidt +1
We prove a new sufficient condition for a cubic 3-connected planar graph to be Hamiltonian. This condition is most easily described as a property of the dual graph. Let be a pl…
Peculiarities of clusters formation in true ternary fission of Cf and U
A. K. Nasirov, W. von Oertzen, A. I. Muminov +1
The existence of a new type of cluster decay called "collinear cluster tri-partition" (CCT) is discussed by an analysis of the landscape of the potential energy surface (PES). The…
What is Ramsey-equivalent to a clique?
Jacob Fox, Andrey Grinshpun, Anita Liebenau +2
A graph G is Ramsey for H if every two-colouring of the edges of G contains a monochromatic copy of H. Two graphs H and H' are Ramsey-equivalent if every graph G is Ramsey for H if…
Thermal Transport and Wiedemann-Franz Law in the Disordered Fermi Liquid
G. Schwiete, A. M. Finkel'stein
We study thermal transport in the disordered Fermi liquid at low temperatures. Gravitational potentials are used as sources for finding the heat density and its correlation functio…
Unconventional topological phase transitions in helical Shiba chains
Falko Pientka, Leonid I. Glazman, Felix von Oppen
Chains of magnetic impurities placed on a superconducting substrate and forming helical spin order provide a promising venue for realizing a topological superconducting phase. An e…
On the precanonical structure of the Schrödinger wave functional
I. V. Kanatchikov
We show that the Schrödinger wave functional may be obtained as the product integral of precanonical wave functions on the space of field and space-time variables. The functional d…
Surface and bulk entanglement in free-fermion chains
Viktor Eisler, Ingo Peschel
We consider free-fermion chains where full and empty parts are connected by a transition region with narrow surfaces. This can be caused by a linear potential or by time evolution…
Fourier expansions of Kac-Moody Eisenstein series and degenerate Whittaker vectors
Philipp Fleig, Axel Kleinschmidt, Daniel Persson
Motivated by string theory scattering amplitudes that are invariant under a discrete U-duality, we study Fourier coefficients of Eisenstein series on Kac-Moody groups. In particula…
The Lipschitz metric on deformation spaces of -trees
Sebastian Meinert
For a finitely generated group , we introduce an asymmetric pseudometric on projectivized deformation spaces of -trees, using stretching factors of -equivariant Lipschitz…
Distributed-Pair Programming can work well and is not just Distributed Pair-Programming
Julia Schenk, Lutz Prechelt, Stephan Salinger
Background: Distributed Pair Programming can be performed via screensharing or via a distributed IDE. The latter offers the freedom of concurrent editing (which may be helpful or d…
On the multicolor Ramsey number of a graph with m edges
Kathleen Johst, Yury Person
The multicolor Ramsey number of a graph is the least integer such that in every coloring of the edges of by colors there is a monochromatic copy of .…
Global analysis of the ground-state wrapping conformation of a charged polymer on an oppositely charged nano-sphere
Hoda Boroudjerdi, Ali Naji, Roland R. Netz
We investigate the wrapping conformations of a strongly adsorbed polymer chain on an oppositely charged nano-sphere by employing a reduced (dimensionless) representation of a primi…
Levy-Lieb Principle meets Quantum Monte Carlo
Luigi Delle Site
We review an approach where the energy functional of Density-Functional Theory (DFT) can be determined without empiricism via a Quantum Monte Carlo (QMC) procedure. The idea consis…
Efficient Decoders for Qudit Topological Codes
Hussain Anwar, Benjamin J. Brown, Earl T. Campbell +1
Qudit toric codes are a natural higher-dimensional generalization of the well-studied qubit toric code. However standard methods for error correction of the qubit toric code are no…
On the Number of Edges of Fan-Crossing Free Graphs
Otfried Cheong, Sariel Har-Peled, Heuna Kim +1
A graph drawn in the plane with n vertices is k-fan-crossing free for k > 1 if there are no k+1 edges , such that have a common endpoint and cros…
Spin Orbit Interaction and Isotropic Electronic Transport in Graphene
Mahmoud M. Asmar, Sergio E. Ulloa
Broken symmetries in graphene affect the massless nature of its charge carriers. We present an analysis of scattering by defects in graphene in the presence of spin-orbit interacti…
Non-Abelian Fractional Chern Insulators from Long-Range Interactions
Zhao Liu, Emil J. Bergholtz, Eliot Kapit
The recent theoretical discovery of fractional Chern insulators (FCIs) has provided an important new way to realize topologically ordered states in lattice models. In earlier works…
Chemical potential of liquids and mixtures via Adaptive Resolution Simulation
Animesh Agarwal, Han Wang, Christof Schütte +1
We employ the adaptive resolution approach AdResS, in its recently developed Grand Canonical-like version (GC-AdResS) [Wang et al. Phys.Rev.X 3, 011018 (2013)], to calculate the ex…
Detecting nonlocality of noisy multipartite states with the CHSH inequality
Rafael Chaves, Antonio Acín, Leandro Aolita +1
The Clauser-Horne-Shimony-Holt inequality was originally proposed as a Bell inequality to detect nonlocality in bipartite systems. However, it can also be used to certify the nonlo…
Topological insulators with arbitrarily tunable entanglement
J. C. Budich, J. Eisert, E. J. Bergholtz
We elucidate how Chern and topological insulators fulfill an area law for the entanglement entropy. By explicit construction of a family of lattice Hamiltonians, we are able to dem…
