Lifshitz transition and magnetic superconductivity in flat band systems
Sudeshna Pal, K. B. Yogendra, Madhuparna Karmakar +1
A Lifshitz transition is a class of non-symmetry-breaking transitions typically associated with metallic systems wherein the Fermi surface changes its connectivity as the chemical…
Critical Behavior and Collective Modes at the Superfluid Transition in Amorphous Systems
Vishnu Pulloor Kuttanikkad, Martin Puschmann, Rajesh Narayanan +1
We investigate the critical behavior and the dynamics of the amplitude (Higgs) mode close to the superfluid-insulator quantum phase transition in an amorphous system (i.e., a syste…
Novel Emergent Phases in a Two-Dimensional Superconductor
Simrandeep Kaur, Hemanta Kumar Kundu, Sumit Kumar +4
In this letter, we report our observation of an extraordinarily rich phase diagram of a LaScO/SrTiO heterostructure. Close to the superconducting transition temperature, th…
Stripe order, impurities, and symmetry breaking in a diluted frustrated magnet
Xuecheng Ye, Rajesh Narayanan, Thomas Vojta
We investigate the behavior of the frustrated - Ising model on a square lattice under the influence of random dilution and spatial anisotropies. Spinless impurities gener…
Signatures of many-body localization and metastability by weak perturbation
Yang Zhao, Rajesh Narayanan, Jaeyoon Cho
Nonequilibrium dynamics in isolated quantum many-body systems displays a number of intriguing features, such as many-body localization (MBL) and prethermalization. Here we investig…
Breathing chromium spinels: a showcase for a variety of pyrochlore Heisenberg Hamiltonians
Pratyay Ghosh, Yasir Iqbal, Tobias Müller +6
We address the long-standing problem of the microscopic origin of the richly diverse phenomena in the chromium breathing pyrochlore material family. Combining electronic structure…
