Topological flowscape reveals state transitions in nonreciprocal living matter
Hyunseok Lee, EliseAnne Koskelo, Shreyas Gokhale +7
Nonreciprocal interactions -- where forces between entities are asymmetric -- govern a wide range of nonequilibrium phenomena, yet their role in structural transitions in living an…
MonoCon: A general framework for learning ultra-compact high-fidelity representations using monotonicity constraints
Shreyas Gokhale
Learning high-quality, robust, efficient, and disentangled representations is a central challenge in artificial intelligence (AI). Deep metric learning frameworks tackle this chall…
Selective excitation of work-generating cycles in nonreciprocal living solids
Yu-Chen Chao, Shreyas Gokhale, Lisa Lin +8
Emergent nonreciprocity in active matter drives the formation of self-organized states that transcend the behaviors of equilibrium systems. Integrating experiments, theory and simu…
The semantic landscape paradigm for neural networks
Shreyas Gokhale
Deep neural networks exhibit a fascinating spectrum of phenomena ranging from predictable scaling laws to the unpredictable emergence of new capabilities as a function of training…
Coupled instabilities drive quasiperiodic order-disorder transitions in Faraday waves
Valeri Frumkin, Shreyas Gokhale
We present an experimental study of quasiperiodic transitions between a highly ordered square-lattice pattern and a disordered, defect-riddled state, in a circular Faraday system.…
Dynamic clustering of passive colloids in dense suspensions of motile bacteria
Shreyas Gokhale, Junang Li, Alexandre Solon +2
Mixtures of active and passive particles are predicted to exhibit a variety of nonequilibrium phases. Here we report a dynamic clustering phase in mixtures of colloids and motile b…
Odd dynamics of living chiral crystals
Tzer Han Tan, Alexander Mietke, Junang Li +6
Active crystals are highly ordered structures that emerge from the self-organization of motile objects, and have been widely studied in synthetic and bacterial active matter. Wheth…
Fast and Scalable Group Mutual Exclusion
Shreyas Gokhale, Neeraj Mittal
The group mutual exclusion (GME) problem is a generalization of the classical mutual exclusion problem in which every critical section is associated with a type or session. Critica…
Deconstructing the glass transition through critical experiments on colloids
Shreyas Gokhale, A. K. Sood, Rajesh Ganapathy
The glass transition is the most enduring grand-challenge problem in contemporary condensed matter physics. Here, we review the contribution of colloid experiments to our understan…
Influence of an amorphous wall on the distribution of localized excitations in a colloidal glass-forming liquid
Shreyas Gokhale, K. Hima Nagamanasa, A. K. Sood +1
Elucidating the nature of the glass transition has been the holy grail of condensed matter physics and statistical mechanics for several decades. A phenomenological aspect that mak…
Robust Neighbor Discovery in Multi-Hop Multi-Channel Heterogeneous Wireless Networks
Yanyan Zeng, K. Alex Mills, Shreyas Gokhale +3
An important first step when deploying a wireless ad hoc network is neighbor discovery in which every node attempts to determine the set of nodes it can communicate with in one wir…
Direct measurements of growing amorphous order and non-monotonic dynamic correlations in a colloidal glass-former
K. Hima Nagamanasa, Shreyas Gokhale, A. K. Sood +1
While the transformation of flowing liquids into rigid glasses is omnipresent, a complete understanding of vitrification remains elusive. Of the numerous approaches aimed at solvin…
Dynamical facilitation governs glassy dynamics in suspensions of colloidal ellipsoids
Chandan K. Mishra, K. Hima Nagamanasa, Rajesh Ganapathy +2
One of the greatest challenges in contemporary condensed matter physics is to ascertain whether the formation of glasses from liquids is fundamentally thermodynamic or dynamic in o…
Growing Dynamical Facilitation on Approaching the Random Pinning Colloidal Glass Transition
Shreyas Gokhale, K. Hima Nagamanasa, Rajesh Ganapathy +1
Despite decades of research, it remains to be established whether the transformation of a liquid into a glass is fundamentally thermodynamic or dynamic in origin. While observation…
Direct Evidence for an Absorbing Phase Transition Governing Yielding of a Soft Glass
K. Hima Nagamanasa, Shreyas Gokhale, A. K. Sood +1
We present the first direct experimental evidence showing that yielding of a prototypical soft solid - a colloidal glass - is a non-equilibrium 'absorbing' phase transition. By sim…
