From atomic to global connectivity in the structure of the SARS-CoV2-Human ACE2 receptor complex
Varsha Subramanyan, Arinnia Anto, Moitrayee Bhattacharyya +2
We investigate connectivity properties of the SARS-CoV2 spike protein-human ACE2-receptor complex employing a protein side chain-based network method that allows us to span a range…
Quantum critical dynamics and emergent universality in decoherent digital quantum processors
Brendan Rhyno, Swarnadeep Majumder, Smitha Vishveshwara +1
Understanding how noise influences nonequilibrium quantum critical dynamics is essential for both fundamental physics and the development of practical quantum technologies. While t…
Shell-shaped Bose-Einstein condensates: Dynamics, excitations, and thermodynamics
Brendan Rhyno, Kuei Sun, Jude Bedessem +3
Shell-shaped Bose-Einstein condensates (BECs) represent a paradigmatic instance of quantum fluids in hollow geometries exhibiting phenomena that bridge from ultracold atomic to ast…
Quantum statistics and self-interference in extended colliders
Sai Satyam Samal, Smitha Vishveshwara, Yuval Gefen +1
Collision of quantum particles remains an effective way of probing their mutual statistics. Colliders based on quantum point contacts in quantum Hall edge states have been successf…
Observing quantum many-body dynamics in emergent curved spacetime using programmable quantum processors
Brendan Rhyno, Bastien Lapierre, Smitha Vishveshwara +2
We digitally simulate quantum many-body dynamics in emergent curved backgrounds using 80 superconducting qubits on IBM Heron processors. By engineering spatially varying couplings…
Dynamics of "Classical" Bosons, Fermions, and beyond
Varsha Subramanyan, T. H. Hansson, Smitha Vishveshwara
We study the classical mechanics and dynamics of particles that retains some memory of quantum statistics. Our work builds on earlier work on the statistical mechanics and thermody…
