Multi-particle gates on driven one-dimensional paths: probing deep traps
Harsh Jain, Shankar Ghosh, Archishman Raju
We study single-file transport of driven overdamped colloidal particles on a periodic path with deep potential wells. In the small trap limit (i.e., trap size smaller than particle…
Evolution of phenocopying in a dynamical model of developmental trajectories
Yuuki Matsushita, Archishman Raju
Developmental trajectories are known to be canalized, or robust to both environmental and genetic perturbations. However, even when these trajectories are decanalized by an environ…
A geometrical perspective on development
Archishman Raju, Eric D. Siggia
Cell fate decisions emerge as a consequence of a complex set of gene regulatory networks. Models of these networks are known to have more parameters than data can determine. Recent…
Normal forms, universal scaling functions, and extending the validity of the RG
James P. Sethna, David Hathcock, Jaron Kent-Dobias +1
Our community has a deep and sophisticated understanding of phase transitions and their universal scaling functions. We outline and advocate an ambitious program to use this unders…
Geometry of Gene Regulatory Dynamics
David A. Rand, Archishman Raju, Meritxell Saez +2
Embryonic development leads to the reproducible and ordered appearance of complexity from egg to adult. The successive differentiation of different cell types, that elaborates this…
Weird scaling for 2-D avalanches: Curing the faceting, and scaling in the lower critical dimension
L. X. Hayden, Archishman Raju, James P. Sethna
The non-equilibrium random-field Ising model is well studied, yet there are outstanding questions. In two dimensions, power law scaling approaches fail and the critical disorder is…
Morphology of renormalization-group flow for the de Almeida-Thouless-Gardner universality class
Patrick Charbonneau, Yi Hu, Archishman Raju +2
A replica-symmetry-breaking phase transition is predicted in a host of disordered media. The criticality of the transition has, however, long been questioned below its upper critic…
Reexamining the renormalization group: Period doubling onset of chaos
Archishman Raju, James P Sethna
We explore fundamental questions about the renormalization group through a detailed re-examination of Feigenbaum's period doubling route to chaos. In the space of one-humped maps,…
Information loss under coarse-graining: a geometric approach
Archishman Raju, Benjamin B. Machta, James P. Sethna
We use information geometry, in which the local distance between models measures their distinguishability from data, to quantify the flow of information under the renormalization g…
Finding stability domains and escape rates in kicked Hamiltonians
Archishman Raju, Sayan Choudhury, David L. Rubin +2
We use an effective Hamiltonian to characterize particle dynamics and find escape rates in a periodically kicked Hamiltonian. We study a model of particles in storage rings that is…
Normal form for renormalization groups
Archishman Raju, Colin B. Clement, Lorien X. Hayden +4
The results of the renormalization group are commonly advertised as the existence of power law singularities near critical points. The classic predictions are often violated and lo…
Deformation of crystals: Connections with statistical physics
James P. Sethna, Matthew K. Bierbaum, Karin A. Dahmen +12
We give a bird's-eye view of the plastic deformation of crystals aimed at the statistical physics community, and a broad introduction into the statistical theories of forced rigid…
Pumping single-file colloids: Absence of current reversal
Debasish Chaudhuri, Archishman Raju, Abhishek Dhar
We consider the single-file motion of colloidal particles interacting via short-ranged repulsion and placed in a traveling wave potential, that varies periodically in time and spac…
