On Mirror Symmetry for Calabi-Yau Fourfolds with Three-Form Cohomology

Sebastian Greiner, Thomas W. Grimm

We study the action of mirror symmetry on two-dimensional N=(2,2) effective theories obtained by compactifying Type IIA string theory on Calabi-Yau fourfolds. Our focus is on fourf…

Stellar winds near massive black holes: The case of the S-stars

Nora Lützgendorf, Edwin van der Helm, Inti Pelupessy +1

The Galactic center provides a unique laboratory to study the interaction of a supermassive black hole (SMBH) with its gaseous and stellar environment. Simulations to determine the…

Resonant plasmon-phonon coupling and its role in magneto-thermoelectricity in bismuth

P. Chudzinski

Using diagrammatic methods we derive an effective interaction between a low energy collective movement of fermionic liquid (acoustic plasmon) and acoustic phonon. We show that the…

Milnor Fibre Homology via Deformation

Dirk Siersma, Mihai Tibar

In case of one-dimensional singular locus, we use deformations in order to get refined information about the Betti numbers of the Milnor fibre.

The influence of dense gas rings on the dynamics of a stellar disk in the Galactic center

Alessandro Alberto Trani, Michela Mapelli, Alessandro Bressan +3

The Galactic center hosts several hundred early-type stars, about 20% of which lie in the so-called clockwise disk, while the remaining 80% do not belong to any disks. The circumnu…

Bose-Einstein Condensation of Magnons Pumped by the Bulk Spin Seebeck Effect

Yaroslav Tserkovnyak, Scott A. Bender, Rembert A. Duine +1

We propose inducing Bose-Einstein condensation of magnons in a magnetic insulator by a heat flow oriented toward its boundary. At a critical heat flux, the oversaturated thermal ga…

Multipion Bose-Einstein correlations in pp, p-Pb, and Pb-Pb collisions at the LHC

ALICE Collaboration

Three- and four-pion Bose-Einstein correlations are presented in pp, p-Pb, and Pb-Pb collisions at the LHC. We compare our measured four-pion correlations to the expectation derive…

Jahn-Teller distortion driven magnetic polarons in magnetite

H. Y. Huang, Z. Y. Chen, R. -P. Wang +11

The first known magnetic mineral, magnetite (FeO), has unusual properties which have fascinated mankind for centuries; it undergoes the Verwey transition at $\s…

Density-induced reentrant melting of colloidal Wigner crystals

Jeffrey Everts, Niels Boon, René van Roij

Electrostatic repulsions can drive crystallization in many-particle systems. For charged colloidal systems, the phase boundaries as well as crystal structure are highly tunable by…

Keeping it Short and Simple: Summarising Complex Event Sequences with Multivariate Patterns

Roel Bertens, Jilles Vreeken, Arno Siebes

We study how to obtain concise descriptions of discrete multivariate sequential data. In particular, how to do so in terms of rich multivariate sequential patterns that can capture…

Beauty and Brains: Detecting Anomalous Pattern Co-Occurrences

Roel Bertens, Jilles Vreeken, Arno Siebes

Our world is filled with both beautiful and brainy people, but how often does a Nobel Prize winner also wins a beauty pageant? Let us assume that someone who is both very beautiful…

N=3 four dimensional field theories

Iñaki García-Etxebarria, Diego Regalado

We introduce a class of four dimensional field theories constructed by quotienting ordinary SYM by particular combinations of R-symmetry and $SL(2,\mathbb{Z}…

Relaxion Monodromy and the Weak Gravity Conjecture

Luis E. Ibanez, Miguel Montero, Angel Uranga +1

The recently proposed relaxion models require extremely large trans-Planckian axion excursions as well as a potential explicitly violating the axion shift symmetry. The latter prop…
