Magnetic anisotropy from linear defect structures in correlated electron systems
Mainak Pal, Laetitia Bettmann, Andreas Kreisel +1
Correlated electron systems, particularly iron-based superconductors, are extremely sensitive to strain, which inevitably occurs in the crystal growth process. Built-in strain of t…
Non-genetic heterogeneity criticality and cell differentiation
Mainak Pal, Sayantari Ghosh, Indrani Bose
The different cell types in a living organism acquire their identity through the process of cell differentiation in which the multipotent progenitor cells differentiate into distin…
Scar-induced imbalance in staggered Rydberg ladders
Mainak Pal, Madhumita Sarkar, K. Sengupta +1
We demonstrate that the kinematically-constrained model of Rydberg atoms on a two-leg ladder with staggered detuning, , has quantum many-body scars (QMBS) in its spect…
Early signatures of regime shifts in gene expression dynamics
Mainak Pal, Amit Kumar Pal, Sayantari Ghosh +1
Recently, a large number of studies have been carried out on the early signatures of sudden regime shifts in systems as diverse as ecosystems, financial markets, population biology…
Allee dynamics: Growth, extinction and range expansion
Indrani Bose, Mainak Pal, Chiranjit Karmakar
In population biology, the Allee dynamics refer to negative growth rates below a critical population density. In this Letter, we study a reaction-diffusion (RD) model of population…
Inhomogeneity, Fluctuations, and Gap Filling in Overdoped Cuprates
Miguel Antonio Sulangi, Willem Farmilo, Andreas Kreisel +3
Several recent experiments have challenged the premise that cuprate high-temperature superconductors approach conventional Landau-BCS behavior in the high-doping limit. We argue, b…
Criticality in Cell Differentiation
Indrani Bose, Mainak Pal
Cell differentiation is an important process in living organisms. Differentiation is mostly based on binary decisions with the progenitor cells choosing between two specific lineag…
Functional Characteristics of Gene Expression Motifs with Single and Dual Strategies of Regulation
Mainak Pal, Sayantari Ghosh, Indrani Bose
Transcriptional regulation by transcription factors and post-transcriptional regulation by microRNAs constitute two major modes of regulation of gene expression. While gene express…
Rydberg Atoms in a Ladder Geometry: Quench Dynamics and Floquet Engineering
Mainak Pal, Tista Banerjee
Rydberg atom quantum simulator platforms are novel quantum simulators for physical systems ranging from condensed matter to particle physics. In this paper, we study out-of-equilib…
Topological superconductivity driven by correlations and linear defects in multiband superconductors
Mainak Pal, Andreas Kreisel, P. J. Hirschfeld
There have been several proposals for platforms sustaining topological superconductivity in high temperature superconductors, in order to make use of the larger superconducting gap…
Minimally driven Kapitza oscillator: A pedagogical perspective from Newtonian mechanics and geometry
Mainak Pal
The unstable top-equilibrium point of a simple pendulum turns stable when its pivot point is given a fast and strong enough vertical vibration. Known as the Kapitza oscillator, it…
Dynamical phase transitions in model: a Monte Carlo and mean-field theory study
Mainak Pal, William D. Baez, Pushan Majumdar +2
We investigate the dynamical phases and phase transitions arising in a classical two-dimensional anisotropic model under the influence of a periodically driven temporal extern…
Generative Model-driven Structure Aligning Discriminative Embeddings for Transductive Zero-shot Learning
Omkar Gune, Mainak Pal, Preeti Mukherjee +2
Zero-shot Learning (ZSL) is a transfer learning technique which aims at transferring knowledge from seen classes to unseen classes. This knowledge transfer is possible because of u…
Simulating Superconducting Properties of Overdoped Cuprates: the Role of Inhomogeneity
Mainak Pal, Andreas Kreisel, W. A. Atkinson +1
Theoretical studies of disordered -wave superconductors have focused, with a few exceptions, on optimally doped models with strong scatterers. Addressing recent controversies ab…
Quantum order-by-disorder induced phase transition in Rydberg ladders with staggered detuning
Madhumita Sarkar, Mainak Pal, Arnab Sen +1
atoms are known to have long-lived Rydberg excited states with controllable excitation amplitude (detuning) and strong repulsive van der Waals interaction $V_{{\bf…
