Exact weak bosonic zero modes in a spin/fermion chain

We study an exactly solvable one-dimensional spin- 12 model which can support weak zero modes in its ground state manifold. The spin chain has staggered XXZ-type and ZZ-type spin interaction on

Electrical studies of Barkhausen switching noise in ferroelectric PZT: Critical exponents and temperature dependence

Pressure-driven collapse of the relativistic electronic ground state in a honeycomb iridate

Honeycomb-lattice quantum magnets with strong spin-orbit coupling are promising candidates for realizing a Kitaev quantum spin liquid. Although iridate materials such as Li2IrO3 and Na2IrO3 have been

Transport Experiments Towards the Quanum Spin Hall Effect in InAs/GaSb

A suitable layer combination of indium arsenide (InAs) and gallium antimonide (GaSb) has been proposed as a candidate for a two-dimensional (2D) topological insulator. This implies the existence of

Slow Dynamics and Kohlrausch Relaxation in Isolated Disordered Many-Body Systems

The Kohlrausch(-Williams-Watts) law of stretched exponential relaxation has been observed for more than a century and a half in diverse complex classical systems. Here we show that this law describes

Quantum Graph Learning: Frontiers and Outlook

This survey investigates the current advances in quantum graph learning (QGL) from three perspectives, i.e., underlying theories, methods, and prospects, to provide a brief but insightful introduction to this emerging field.

Ferromagnetic domains in the large-$U$ Hubbard model with a few holes: an FCIQMC study

Two-dimensional Hubbard lattices with two or three holes are investigated as a function of U in the large- U limit. In the so-called Nagaoka limit (one-hole system at infinite U ), it is known that

Weak-Coupling Theory of Pair Density-Wave Instabilities in Transition Metal Dichalcogenides

The possibility of realizing pair density wave (PDW) phases, in which Cooper pairs have a finite momentum, presents an interesting challenge that has been studied in a wide variety of systems. In

Effect of anisotropy on the formation of active particle films.

Active colloids belong to a class of nonequilibrium systems where energy uptake, conversion, and dissipation occur at the level of individual colloidal particles, which can lead to particles'

Commensurate-Incommensurate Transitions of the 1D Disordered Chiral Clock Model

We study the effects of quenched disorder on the commensurate-incommensurate transitions in the 1D Z N chiral clock model. The interplay of domain walls and rare regions rounds the sharp transitions
