The Physics of Quantum 2.0: Challenges in understanding Quantum Matter
Siddhartha Lal, Mayank Shreshtha
Almost a century on from the culmination of the first revolution in quantum physics, we are poised for another. Even as we engage in the creation of impactful quantum technologies,…
Tomonaga-Luttinger liquid and quantum criticality in spin-1/2 antiferromagnetic Heisenberg chain C14H18CuN4O10 via Wilson ratio
Sharath Kumar Channarayappa, Sankalp Kumar, N. S. Vidhyadhiraja +9
The ground state of a one-dimensional spin-1/2 uniform antiferromagnetic Heisenberg chain (AfHc) is a Tomonaga-Luttinger liquid which is quantum-critical with respect to applied ma…
Kondo frustration via charge fluctuations: a route to Mott localisation
Abhirup Mukherjee, N. S. Vidhyadhiraja, A. Taraphder +1
We propose a minimal effective impurity model that captures the phenomenology of the Mott-Hubbard metal-insulator transition (MIT) of the half-filled Hubbard model on the Bethe lat…
Holographic entanglement renormalisation for fermionic quantum matter
Abhirup Mukherjee, Siddhartha Patra, Siddhartha Lal
We demonstrate the emergence of a holographic dimension in a system of 2D non-interacting Dirac fermions placed on a torus, by studying the scaling of multipartite entanglement mea…
Universal entanglement signatures of quantum liquids as a guide to fermionic criticality
Siddhartha Patra, Anirban Mukherjee, Siddhartha Lal
An outstanding challenge involves understanding the many-particle entanglement of liquid states of quantum matter that arise in systems of interacting electrons. The Fermi liquid (…
Frustration shapes multi-channel Kondo physics: a star graph perspective
Siddhartha Patra, Abhirup Mukherjee, Anirban Mukherjee +3
We study the overscreened multi-channel Kondo (MCK) model using the recently developed unitary renormalization group (URG) technique. Our results display the importance of ground s…
