Scaling of entanglement entropy at quantum critical points in random spin chains
Prashant Kumar, R. N. Bhatt
We study the scaling properties of the entanglement entropy (EE) near quantum critical points in interacting random antiferromagnetic (AF) spin chains. Using density-matrix renorma…
Nagaoka ferromagnetism in doped Hubbard models in optical lattices
Rhine Samajdar, R. N. Bhatt
The search for ferromagnetism in the Hubbard model has been a problem of outstanding interest since Nagaoka's original proposal in 1966. Recent advances in quantum simulation have…
Entanglement Entropy Growth in Disordered Spin Chains with Tunable Range Interactions
Youcef Mohdeb, Javad Vahedi, Ravindra N. Bhatt +2
The non-equilibrium dynamics of disordered many-body quantum systems after a global quantum quench unveils important insights about the competition between interactions and disorde…
Possible continuous transition from fractional quantum Hall to stripe phase at
Prashant Kumar, R. N. Bhatt
We study the phase diagram of state in the Landau level in the presence of band mass anisotropy. Using density matrix renormalization group on an infinite cylinder…
Beyond the universal Dyson singularity for 1-D chains with hopping disorder
Akshay Krishna, R. N. Bhatt
We study a simple non-interacting nearest neighbor tight-binding model in one dimension with disorder, where the hopping terms are chosen randomly. This model exhibits a well-known…
Topology and many-body localization
R. N. Bhatt, Akshay Krishna
We discuss the problem of localization in two dimensional electron systems in the quantum Hall (single Landau level) regime. After briefly summarizing the well-studied problem of A…
