Shear effects in active models of normal and cancer cells
Souvik Sadhukhan, Rajsekhar Das, Lin Zhao +2
Mechanical properties of biological tissues, driven by passive and active forces, play a vital role in several processes ranging from development to cancer metastasis. However, the…
Controlling the morphologies and dynamics in three-dimensional tissues
Rajsekhar Das, Xin Li, Sumit Sinha +1
A number of factors, such as, cell-cell interactions and self-propulsion of cells driven by cytoskeletal forces determine tissue morphologies and dynamics. To explore the interplay…
Collective dynamic length increases monotonically in pinned and unpinned glass forming systems
Rajsekhar Das, T. R. Kirkpatrick, D. Thirumalai
The Random First Order Transition Theory (RFOT) predicts that transport proceeds by cooperative movement of particles in domains whose sizes increase as a liquid is compressed abov…
Free volume theory explains the unusual behavior of viscosity in a non-confluent tissue during morphogenesis
Rajsekhar Das, Sumit Sinha, Xin Li +2
A recent experiment on zebrafish blastoderm morphogenesis showed that the viscosity (η) of a non-confluent embryonic tissue grows sharply until a critical cell packing fraction (ϕS…
Mechanical feedback controls the emergence of dynamical memory in growing tissue monolayers
Sumit Sinha, Xin Li, Rajsekhar Das +1
The growth of a tissue, which depends on cell-cell interactions and biologically relevant process such as cell division and apoptosis, is regulated by a mechanical feedback mechani…
Soft-Pinning: Experimental Validation of Static Correlations in Supercooled Molecular Glass-forming Liquids
Rajsekhar Das, Bhanu Prasad Bhowmik, Anand B. Puthirath +2
Enormous enhancement in the viscosity of a liquid near its glass transition is generally connected to the growing many-body static correlations near the transition, often coined as…
Time Scales of Fickian Diffusion and the Lifetime of Dynamic Heterogeneity
Rajsekhar Das, Chandan Dasgupta, Smarajit Karmakar
Dynamic heterogeneity, believed to be one of the hallmarks of the dynamics of supercooled liquids, is expected to affect the diffusion of the particles comprising the liquid. We ha…
Possible Universal Relation Between Short time -relaxation and Long time -relaxation in Glass-forming Liquids
Rajsekhar Das, Indrajit Tah, Smarajit Karmakar
Relaxation processes in supercooled liquids are known to exhibit interesting as well as complex behavior. One of the hallmarks of this relaxation process observed in the measured a…
Pinning Susceptibility : A Novel Method to Study Growth of Amorphous Order in Glass-forming Liquids
Rajsekhar Das, Saurish Chakrabarty, Smarajit Karmakar
Existence and growth of amorphous order in supercooled liquids approaching glass transition is a subject of intense research. Even after decades of work, there is still no clear co…
Understanding the Dynamics of Glass-forming Liquids with Random Pinning within the Random First Order Transition Theory
Saurish Chakrabarty, Rajsekhar Das, Smarajit Karmakar +1
Extensive computer simulations are performed for a few model glass-forming liquids in both two and three dimensions to study their dynamics when a randomly chosen fraction of parti…
Understanding Stokes-Einstein Relation in Supercooled Liquids using Random Pinning
Bhanu Prasad Bhowmik, Rajsekhar Das, Smarajit Karmakar
Breakdown of Stokes-Einstein relation in supercooled liquids is believed to be one of the hallmarks of glass transition. The phenomena is studied in depth over many years to unders…
