Breakdown and Restoration of Hydrodynamics in Dipole-conserving Active Fluids
Anish Chaudhuri, Lokrshi Prawar Dadhichi, Arijit Haldar
We present a general hydrodynamic theory for active fluids, capable of describing living matter, that conserve center of mass or dipole moment. Imposition of dipole or center-of-ma…
Universal non-equilibrium dynamics of pure states and density-dependent thermalization in Sachdev-Ye-Kitaev model
Rishik Perugu, Arijit Haldar, Sumilan Banerjee
Non-equilibrium dynamics of unentangled and entangled pure states in interacting quantum systems is crucial for harnessing quantum information and to understand quantum thermalizat…
Hidden Critical Points in the Two-Dimensional model: Exact Numerical Study of a Complex Conformal Field Theory
Arijit Haldar, Omid Tavakol, Han Ma +1
The presence of nearby conformal field theories (CFTs) hidden in the complex plane of the tuning parameter was recently proposed as an elegant explanation for the ubiquity of "weak…
Dynamical mean-field theory for Rényi entanglement entropy and mutual Information in Hubbard Model
Surajit Bera, Arijit Haldar, Sumilan Banerjee
Quantum entanglement, lacking any classical counterpart, provides a fundamental new route to characterize the quantum nature of many-body states. In this work, we discuss an implem…
Chiral Broken Symmetry Descendants of the Kagomé Lattice Chiral Spin Liquid
Anjishnu Bose, Arijit Haldar, Erik S. Sørensen +1
The breaking of chiral and time-reversal symmetries provides a pathway to exotic quantum phenomena and topological phases. In particular, the breaking of chiral (mirror) symmetry i…
Probing magnetic anisotropy and spin-reorientation transition in 3D antiferromagnet, HoDyFeOPt using spin Hall magnetoresistance
Aditya A. Wagh, Priyanka Garg, Arijit Haldar +4
Orthoferrites (FeO) containing rare-earth () elements are 3D antiferromagnets (AFM) that exhibit characteristic weak ferromagnetism originating due to slight canting…
Nematic phases and elastoresistivity from a multiorbital non-Fermi liquid
Andrew Hardy, Arijit Haldar, Arun Paramekanti
We propose and study a two-orbital lattice extension of the Sachdev-Ye-Kitaev model in the large- limit. The phase diagram of this model features a high temperature isotropic st…
Octupolar order and Ising quantum criticality tuned by strain and dimensionality: Application to -orbital Mott insulators
Sreekar Voleti, Arijit Haldar, Arun Paramekanti
Recent experiments have discovered multipolar orders in a variety of -orbital Mott insulators. Motivated by uncovering the exchange interactions which underlie octupolar order p…
Higher-order topology and corner triplon excitations in two-dimensional quantum spin-dimer models
Arijit Haldar, Geremia Massarelli, Arun Paramekanti
The concept of free fermion topology has been generalized to -dimensional phases that exhibit -dimensional boundary modes, such as zero-dimensional (0D) corner excitation…
Variational wavefunctions for Sachdev-Ye-Kitaev models
Arijit Haldar, Omid Tavakol, Thomas Scaffidi
Given a class of -local Hamiltonians, is it possible to find a simple variational state whose energy is a finite fraction of the ground state energy in the thermodynamic limit?…
