Safety for Whom? Boundary-Aware Self-Distillation for Controlled LLM Safety Refusal

Alejo López-Ávila, Iker García-Ferrero, Jezabel Garcia +2

Safety alignment is usually posed as a topic-level question: is this subject harmful? Deployments ask a narrower one. A civics tutor and a public-sector assistant may share a base…

Quantization-Aware Healing: A Practical Recipe for Recovering Compressed, 4-Bit LLMs

Bakbergen Ryskulov, Iker García-Ferrero, David Montero +5

Serving large language models cheaply increasingly means shipping models that are both structurally compressed to a fraction of their parameters and quantized to 4 bits. Together t…

Efficient Knowledge Distillation for LLMs: Offline Top-K Logits and a Fused Chunked KL Loss

Bakbergen Ryskulov, Iker García-Ferrero, David Montero +5

Small language models are often the only option for deployment under tight latency, cost, and on-premises constraints, but they are rarely trained from scratch: a compressed model…

Room-temperature tuning and probing of Fermi polarons in atomically thin semiconductors on a plasmonic metasurface

Tingting Wu, Francesca Maria Marchetti, Antonio Tiene +9

The Fermi polaron, arising from interactions between a mobile impurity and a degenerate Fermi sea, is a many-body quasiparticle that provides a sensitive probe of strongly correlat…

Scaling Laws for Energy Efficiency of Local LLMs

Ander Alvarez, Alessandro Genuardi, Nilotpal Sinha +6

Deploying local large language models and vision-language models on edge devices requires balancing accuracy with constrained computational and energy budgets. Although graphics pr…

Efficient calculation of trion energies in monolayer transition metal dichalcogenides

Sangeet S. Kumar, Brendan C. Mulkerin, Antonio Tiene +3

The reduced dielectric screening in atomically thin semiconductors leads to remarkably strong electron interactions. As a result, bound electron-hole pairs (excitons) and charged e…

Multiple polaron quasiparticles with dipolar fermions in a bilayer geometry

A. Tiene, A. Tamargo Bracho, M. M. Parish +2

We study the Fermi polaron problem with dipolar fermions in a bilayer geometry, where a single dipolar particle in one layer interacts with a Fermi sea of dipolar fermions in the o…

Crossover from exciton polarons to trions in doped two-dimensional semiconductors at finite temperature

A. Tiene, B. C. Mulkerin, J. Levinsen +2

We study systematically the role of temperature in the optical response of doped two-dimensional semiconductors. By making use of a finite-temperature Fermi-polaron theory, we reve…

Exact Quantum Virial Expansion for the Optical Response of Doped Two-Dimensional Semiconductors

B. C. Mulkerin, A. Tiene, F. M. Marchetti +2

We present a quantum virial expansion for the optical response of a doped two-dimensional semiconductor. As we show, this constitutes a perturbatively exact theory in the high-temp…

Effect of fermion indistinguishability on optical absorption of doped two-dimensional semiconductors

A. Tiene, J. Levinsen, J. Keeling +2

We study the optical absorption spectrum of a doped two-dimensional semiconductor in the spin-valley polarized limit. In this configuration, the carriers in the Fermi sea are indis…

Extremely imbalanced two-dimensional electron-hole-photon systems

A. Tiene, J. Levinsen, M. M. Parish +3

We investigate the phases of two-dimensional electron-hole systems strongly coupled to a microcavity photon field in the limit of extreme charge imbalance. Using variational wave f…
