Abstract: In this paper, we study the geometric phase (GP) of two-mode entangled squeezed-coherent states (ESCSs), undergoing a unitary cyclic evolution. It is revealed that by increasing the squeezing parameter of the first or the second mode of a balanced ESCS, the GP compresses in an elliptical manner along the axis of the coherence parameter of the corresponding mode. While in the case of unbalanced ESCS, the GP compresses in a hyperbolic manner by increasing the squeezing parameters of either mode. By generalizing to higher constituting-state dimensions, it is found that the GPs of both balanced and unbalanced ESCSs, increase for a specific value of the coherence parameter. Based on these findings, using the interferometry approach, we suggest a theoretical scheme for the physical generation of the balanced ESCS.

Entanglement and the density matrix renormalisation group in the generalised Landau paradigm [0.0]
We leverage the interplay between gapped phases and dualities of symmetric one-dimensional quantum lattice models. For every phase in the phase diagram, the dual representation of the ground state that breaks all symmetries minimises both the entanglement entropy and the required number of variational parameters. Our work testifies to the usefulness of generalised non-invertible symmetries and their formal category theoretic description for the nuts and bolts simulation of strongly correlated systems.

Stochastic parameter optimization analysis of dynamical quantum critical phenomena in long-range transverse-field Ising chain [0.0]
We explore the quantum phase transition of the one-dimensional long-range transverse-field Ising model. In our simulations, the simulator automatically determines the parameters to sample from, even without prior knowledge of the critical point and universality class. We successfully obtained numerical evidence supporting $sigma = 7/4$ as the universality boundary between the latter two.

Effects of detuning on $\mathcal{PT}$-symmetric, tridiagonal, tight-binding models [0.0]
Non-Hermitian, tight-binding $mathcalPT$-symmetric models are extensively studied in the literature. Here, we investigate two forms of non-Hermitian Hamiltonians to study the $mathcalPT$-symmetry breaking thresholds and features of corresponding surfaces of exceptional points (EPs) Taken together, our results provide a detailed understanding of detuned tight-binding models with a pair of gain-loss potentials.

Quantum chaos and thermalization in the two-mode Dicke model [77.34726150561087]
We discuss the onset of quantum chaos and thermalization in the two-mode Dicke model. The two-mode Dicke model exhibits normal to superradiant quantum phase transition. We show that the temporal fluctuations of the expectation value of the collective spin observable around its average are small and decrease with the effective system size.

We compute the geometric phases acquired in both unitary and dissipative Jaynes-Cummings models. In the dissipative model, the non-unitary effects arise from the outflow of photons through the cavity walls. We show the geometric phase is robust, exhibiting a vanishing correction under a non-unitary evolution.
