Extracting the physical content of Liouvillian eigenmodes: Semiclassical quantization
Ashlin V Thomas, Felix Fritzsch, Masudul Haque +1
Unlike in closed quantum systems where individual energy eigenstates are understood as physical excitations, open quantum systems have distinct right and left eigenstates of the Li…
Emergence of a molecular quantum liquid in one dimension
Rajashri Parida, Biswajit Paul, Harish S. Adsule +4
We investigate the fate of a one-dimensional lattice superfluid formed by hard-core bosons, aka `atoms' (alternatively, a free spinless Fermi sea) subjected to nearest-neighbor att…
Shaping Magnetic Order by Local Frustration for Itinerant Fermions on a Graph
Revathy B S, Shovan Dutta
Kinetic magnetism is an iconic and rare example of collective quantum order that emerges from the interference of paths taken by a hole in a sea of strongly interacting fermions. H…
Symmetry-controlled thermal activation in pyramidal Coulomb clusters: Testing Kramers-Langer theory
Akhil Ayyadevara, Anand Prakash, Shovan Dutta +2
Laser-cooled ions confined in electromagnetic traps provide a unique, tunable mesoscopic system where the interplay of the trapping potential, nonlinear Coulomb interactions, and l…
Frustrated Quantum Magnetism on Complex Networks: What Sets the Total Spin
Preethi Gopalakrishnan, Shovan Dutta
Consider equal antiferromagnetic Heisenberg interactions between qubits forming a complex, nonbipartite network. We ask the question: How does the network topology determine the ne…
Observing the dynamics of octupolar structural transitions in trapped-ion clusters
Akhil Ayyadevara, Anand Prakash, Shovan Dutta +2
Interacting many-particle systems can self-organize into a rich variety of crystalline structures. While symmetry provides a powerful framework for predicting whether transitions b…
