Ordering According to Size of Disks in a Narrow Channel

Dan Liu, Michael Karbach, Gerhard Müller

A long and narrow channel confines disks of two sizes. The disks are randomly agitated in a widened channel under moderate pressure, then jammed according to a tunable protocol. We…

Thermodynamic Formalism on the Skorokhod space: the continuous time Ruelle operator, entropy, pressure, entropy production and expansiveness

J. Knorst, A. O. Lopes, G. Muller +1

Consider the semi-flow given by the continuous time shift , , acting on the of \textit{càdlàg} paths $w: [0,\infty) \to S…

Jammed disks of two sizes in a narrow channel

Dan Liu, Gerhard Müller

A granular-matter model is exactly solved, where disks of two sizes and weights in alternating sequence are confined to a narrow channel. The axis of the channel is horizontal and…

Quasiparticles in the XXZ model

Ping Lu, Gerhard Muller, Michael Karbach

The coordinate Bethe ansatz solutions of the XXZ model for a one-dimensional spin-1/2 chain are analyzed with focus on the statistical properties of the constituent quasiparticles.…

Spinon excitations in the XX chain: spectra, transition rates, observability

Mitsuhiro Arikawa, Michael Karbach, Gerhard Muller +1

The exact one-to-one mapping between (spinless) Jordan-Wigner lattice fermions and (spin-1/2) spinons is established for all eigenstates of the one-dimensional s = 1=2 XX model on…

Spectrum and transition rates of the XX chain analyzed via Bethe ansatz

Daniel Biegel, Michael Karbach, Gerhard Muller +1

As part of a study that investigates the dynamics of the s=1/2 XXZ model in the planar regime |Delta|<1, we discuss the singular nature of the Bethe ansatz equations for the case D…
