Quantum Mpemba effect from Stark localization
Nico Albert, Masudul Haque, Shovan Dutta
In classical systems, rugged potential energy landscapes provide a transparent mechanism for the celebrated Mpemba effect, in which hotter initial states cool down faster. This pic…
Interpreting Liouvillian Eigenmodes: Quantized Orbits in Dissipative Systems
Ashlin V Thomas, Felix Fritzsch, Masudul Haque +1
In closed quantum dynamics, energy eigenstates represent physical excitations which, for systems with a classical limit, localize on quantized orbits in phase space. Such a picture…
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…
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…
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…
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…
Anti-thermalization: Heating by cooling and vice versa
Jaswanth Uppalapati, Paul A McClarty, Masudul Haque +1
Common intuition tells us that if one part of a connected system is cooled continuously, the other parts should also cool down. This intuition can be given a microscopic foundation…
Hierarchy of degenerate stationary states in a boundary-driven dipole-conserving spin chain
Apoorv Srivastava, Shovan Dutta
Kinetically constrained spin chains serve as a prototype for structured ergodicity breaking in isolated quantum systems. We show that such a system exhibits a hierarchy of degenera…
Quantum Origin of Limit Cycles, Fixed Points, and Critical Slowing Down
Shovan Dutta, Shu Zhang, Masudul Haque
Among the most iconic features of classical dissipative dynamics are persistent limit-cycle oscillations and critical slowing down at the onset of such oscillations, where the syst…
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…
