## One-dimensional noninteracting topological insulators with chiral symmetry

Polina Matveeva, Tyler Hewitt, Donghao Liu, Kethan Reddy, Dmitri B Gutman, Sam T Carr
Abstract

We construct microscopical models of one-dimensional noninteracting topological insulators in all of the chiral universality classes. Specifically, we start with a deformation of the Su-Schrieffer-Heeger (SSH) model that breaks time-reversal symmetry, which is in the AIII class. We then couple this model to its time-reversal counterpart in order to build models in the

## Tracking nanoscale perturbation in active disordered media

Renu Yadav, Patrick Sebbah, Maruthi M Brundavanam, BN Shivakiran Bhaktha
Abstract

Disorder-induced feedback makes random lasers very susceptible to any changes in the scattering medium. The sensitivity of the lasing modes to perturbations in the disordered systems has been utilized to map the regions of perturbation. A tracking parameter that takes into account the cumulative effect of changes in the spatial distribution of the lasing modes of the

## Brownian particles in periodic potentials: Coarse-graining versus fine structure

Abstract

We study the motion of an overdamped particle connected to a thermal heat bath in the presence of an external periodic potential in one dimension. When we coarse-grain, i.e., bin the particle positions using bin sizes that are larger than the periodicity of the potential, the packet of spreading particles, all starting from a common origin, converges to a normal

## Peptide Bond Formation in Protonated Serine Dimer Following VUV Photon-Induced Excitation

Ori Licht, Dario Barreiro-Lage, Patrick Rousseau, Alexandre Giuliani, Aleksandar R Milosavljević, Avinoam Isaak, Yitzhak Mastai, Amnon Albeck, Raj Singh, Vy Nguyen, Laurent Nahon, Lara Martinez,
Abstract

Possible routes for intra-cluster bond formation (ICBF) in protonated serine dimers have been studied. We found no evidence of ICBF following low energy collision induced dissociation (in correspondence with previous works), however, we do observe clear evidence for ICBF following photon absorption in the $4.6-14$ eV range. Moreover, the comparison of photon induced

## Simulating the Interplay of Particle Conservation and Long-Range Coherence

Emanuele G Dalla Torre, Matthew J Reagor
Abstract

Lasers and Bose-Einstein condensates (BECs) exhibit macroscopic quantum coherence in seemingly unrelated ways. Lasers possess a well-defined global phase while the number of photons fluctuates. In BECs of atoms, instead, the number of particles is conserved and the global phase is undefined. Here, we use gate-based quantum circuits to create a unified framework

## Towards precise optical measurements of steady state of and small changes in resting membrane potentials

Debjit Roy, Xavier Michalet, Kiran Bharadwaj, Evan W Miller, Yijie Wang, Arjun Deb, Michael A Wayne, Claudio Bruschini, Edoardo Charbon, Mahbanoo Vakili, Robert P Gunsalus, Robert T Clubb,
Abstract

While great progress has been achieved in developing optical methods for measuring fast changes in membrane potential (like action potentials) in excitable cells, less progress has been made in precise (and calibrated) measurements of steady state resting membrane potentials (RMPs) and small changes in RMPs (in excitable or non-excitable cells). In excitable cells, small

## Increased earthquake rate prior to mainshocks

Abstract

According to the Omori-Utsu law, the rate of aftershocks after a mainshock decays as a power law with an exponent close to 1. This well-established law was intensively used in the past to study and model the statistical properties of earthquakes. Moreover, according to the so-called inverse Omori law, the rate of earthquakes should also increase prior to a mainshock --

## External field and critical exponents in controlling dynamics on complex networks

Abstract

Dynamical processes on complex networks, ranging from biological, technological and social systems, show phase transitions (PTs) between distinct global states of the system. Often, such transitions rely upon the interplay between the structure and dynamics that takes place on it, such that weak connectivity, either sparse network or frail interactions, might lead to

## Ray Engineering from Chaos to Order in 2D Optical Cavities

Chenni Xu, Li-Gang Wang, Patrick Sebbah
Abstract

Chaos, namely exponential sensitivity to initial conditions, is generally considered a nuisance, inasmuch as it prevents long-term predictions in physical systems. Here, an easily accessible approach to undo deterministic chaos and tailor ray trajectories in arbitrary 2D optical billiards by introducing spatially varying refractive index therein is presented. A new
